Hi,
Regarding your initial problem, you can refer to the below link :-
http://www.bba-reman.com/content.aspx?content=NEXT_DTC_P0122
I believe it has been fixed.
Now, for error 1121,
Hi there! The code is for the electronic throttle control actuator. In other words, there is a problem with the electronic throttle body on the car. I would start by checking the wiring to the car,make sure it is plugged in tight. If you had it off to change the valve covers it is possible it is not plugged in properly. If you cleaned it with carb cleaner then you may have done damage to the electric motors inside and it may need to be replaced.

Any further help, let me know.
Thanks for using "Fixya".

Ride height specification for 2002 Bravada and procedure on replacing sensors.Or where can I look on line for this information.


Air Suspension ??????

Air Suspension Description and Operation
Air Suspension
The primary mission of the Air Suspension System is the following for the rear suspension under loaded and unloaded conditions:
• Keep the vehicle visually level
• Provide optimal headlight aiming
• Maintain optimal ride height
The Air Suspension System consists of the following items:
• Air suspension compressor assembly
• Air suspension sensors
• Rear air springs
Important: The Air Suspension System must have a voltage supply of at least 12.6V to operate properly.
The Air Suspension System will maintain the rear D height within 4 mm (0.15 in) in all loading conditions and the leveling function will deactivate if the vehicle is overloaded. The side to side D height variation is maintained within 8 mm (0.31 in). After ignition is turned off, the air suspension control module (ASCM) will remain active for between 30 minutes and 2 1/2 hours. The system will exhaust pressure within 30 minutes after the ignition is turned off to lower the vehicle after unloading. In a temperature-controlled environment, the leakage of the complete load leveling system will not result in more than 1.4 mm (0.05 in) drop of rear suspension height at GVWR during a 24 hour period. If the outdoor temperature drops from +20°C (+68°F) to -5°C (+23°F), the rear D height may drop as much as 25 mm (1 in). However, the Air Suspension System should return to the specified D height when the ignition is again cycled to ON.

What is the problem ?

Diagnostic Trouble Code (DTC) Displaying
The Air Suspension system has an internal clock to prevent overheating if the compressor assembly is running for a prolonged period of time. If the system overheats, all leveling function stops until the system cools down. During this time, the indicator LED on the air inflator switch will be quickly flashing at a constant rate.
The other three diagnostic trouble codes are displayed with a blink code on the inflator switch LED. The Air Suspension Compressor Assembly shall begin to indicate the code when the condition to cause the code becomes current.
The number of the fault code shall be represented by the number of flashing pulses on the inflator switch LED. The flashing pulses shall have a repetition rate of 0.5 seconds and each code shall be separated by a 3.0 second delay. All codes shall be flashed in the order of occurrence of the fault. The blink code shall take priority over other processes that have access to the inflator switch LED. Refer to the following:
• DTC 001
• DTC 002
• DTC 003

05 gmc canyon traction control power fault


First you'll need to take it to have DTC's - diagnostic trouble codes check to find out what part of the system is at fault ! Could have a sensor , control module ,or wiring problem !
Traction Off Indicator The traction off indicator, which is a LED located on the traction control switch, illuminates only when the traction control switch has been pressed and released, disabling traction control. It is important to note that a traction fault does not illuminate this indicator and that there is no relationship between this indicator and the traction fault message.
Traction Fault Message The IPC displays the traction fault message when either of the following instances occur.
?€¢
The EBCM detects a malfunction that requires traction control to be disabled. The EBCM sends a serial data message to the IPC requesting that the message be displayed.


?€¢
The IPC detects a loss of serial data communication with the EBCM


Traction Control System (TCS)
When drive wheel slip is noted while the brake is not applied, the EBCM will enter traction control mode.
The EBCM uses a 5-volt pulse-width modulated (PWM) signal to request the PCM to reduce the amount of torque to the drive wheels. The PCM reduces torque to the drive wheels by retarding spark timing and by commanding the throttle actuator control. The PCM uses a 5-volt PWM signal in order to report to the EBCM the amount of torque delivered to the drive wheels.
You would need a factory grade scan tool to check data PID's - parameter identification , all the sensors work within a specific voltage range 1- 5 volts an you can see this on a good scan tool !
The Traction control is part of the ABS system an there a several DTC possible
DTC B0827 DTC B0828 DTC B2745 DTC C0035 DTC C0035 or C0040 DTC C0040 DTC C0055 DTC C0110 DTC C0191 DTC C0201 DTC C0220-C0229 DTC C0240 or P0856 DTC C0244 or P1689 DTC C0245 DTC C0267 or C0268 and C067 or C068 DTC C0550 DTC C0899 DTC C0900
You best bet is to take it to a qualified repair shop !

DTC P0506

Circuit Description

The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

I keep getting all these cods p0102 p1120 p1220 p1221 p1514 p1516 p0102 p1120


Hi Robert, It would help us to know which vehicle as the codes very well may be vehicle specific.Ford seem to have codes of that numerical range, so I'm assuming your vehicle is made by Ford.
P1120 refers to the Air flow sensor. P1120 the throttle position sensor. 1220 Series Throttle Control Fault (probably related to the TPS) 1221 Refers to the high speed fuel pump relay having been activated. 1516 Intake manifold runner input error. Cannot find P1514 Hope this is helpful. I suggest sorting out the air flow sensor and the throttle position sensor to begin with and that may sort out the other defects. Very often one sensor giving an error reading will trigger others. Regards John

Have 2006 gmc canyon having trouble with it staying on.3.5 engine starts up,stays on a few seconds then shuts off shows reduced power on panel.won't crank over .have to wait a few minutes then it


REDUCED POWER
Refer to:
• Powertrain Control Module Description for the 2.8L engine
• Powertrain Control Module Description for the 3.5L engine

Throttle Actuator Control (TAC) System
Throttle Actuator Control (TAC) Overview
The throttle actuator control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. This eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body. This system also performs the cruise control functions as well.
The TAC system components include, but are not limited to the following:
• The accelerator pedal position (APP) sensors
• The throttle body
• The powertrain control module (PCM)
Each of these components interface together to ensure accurate calculations and control of the throttle position.

Accelerator Pedal Position (APP) Sensor
The accelerator pedal position (APP) sensor is mounted on the accelerator pedal assembly. The APP is 2 individual APP sensors within one housing. There are 2 separate signal, low reference, and 5-volt reference circuits. APP sensor 1 voltage increases as the accelerator pedal is depressed. APP sensor 2 voltage decreases as the accelerator pedal is depressed.
Throttle Body Assembly
The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signals, low reference, and 5-volt reference circuits are used to connect the TP sensors and the powertrain control module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.

Reduced Engine Power Mode
When the PCM detects a problem with the throttle actuator control (TAC) system the PCM enters one of the following Reduced Engine Power Modes:
• Acceleration Limiting--The control module will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited.
• Limited Throttle Mode--The control module will continue to use the accelerator pedal for throttle control, however the maximum throttle opening is limited.
• Throttle Default Mode--The control module will turn OFF the throttle actuator.
• Forced Idle Mode--The control module will perform the following actions:
- Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned OFF.
- Ignore accelerator pedal input.
• Engine Shutdown Mode--The control module will disable fuel and de-energize the throttle actuator.

Have you had it checked for DTC'S - diagnostic trouble codes ?

DTC P2176
The commanded throttle position (TP) is compared to the actual TP. Both values should be within a calibrated range of each other. The powertrain control module (PCM) continuously monitors the commanded and actual TPs. If the values are greater than the calibrated range, DTC P2176 sets.
--------------------------------------------------------------------------------
DTC P2138
The accelerator pedal position (APP) sensors 1 and 2 are located within the accelerator pedal assembly. Each sensor has the following circuits:
• A 5-volt reference circuit
• A low reference circuit
• A signal circuit
This provides the powertrain control module (PCM) with a signal voltage proportional to accelerator pedal movement. The APP sensor 1 signal voltage at rest position is near the low reference and increases as the pedal is actuated. The APP sensor 2 signal voltage at rest position is near the 5-volt reference and decreases as the pedal is actuated.
DTC P2135
The throttle actuator control (TAC) assembly has 2 throttle position (TP) sensors mounted within the assembly. The powertrain control module (PCM) provides individual signal, ground, and 5-volt reference circuits to each sensor. Both sensors operate within a voltage range between 0.35-4.65 volts. When the throttle is opened from 0-100 percent, one sensor signal voltage increases while the other decreases. The signal circuit for TP sensor 1 is referenced to ground, and the signal circuit for TP sensor 2 is pulled up to 5 volts within the PCM.

Nissan pathfinder 2004 turbo diesel trouble code p1275


This answer is coutesy of expert ZL Limited

DTC P1275 - Acceleration Position Sensor 1 Circuit Malfunction
The acceleration position (AP) sensor circuit provides a voltage signal relative to acceleration pedal angle. The acceleration pedal angle (AP1) will vary about 13% at idle position to about 87% at wide open throttle (WOT). This code detects a continuous short to ground or high in either the circuit or the sensor.

9_4_2012_8_23_06_pm.gif
Conditions for setting the DTC:
* The Ignition is "ON".
* The acceleration pedal angle is less than 2.5% or more than 97% for 12 counts within 500 test samples (15.6 m sec ).

Action Taken When the DTC Sets:
* The PCM will store condition which were present when the DTC was set as Freeze Frame and in the Failure Records data.

Conditions for Clearing the MIL/DTC:
* The PCM will turn the MIL "OFF" on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
* A history DTC P1275 will clear after 40 consecutive trip cycle during which the warm up cycles have occurred without a fault.
* DTC P1275 can be cleared using the Tech 2 "Clear Info" function or by disconnecting the PCM battery feed.

9_4_2012_8_23_55_pm.gif

Diagnostic Aids
An intermittent may be caused by the following:
* Poor connections.
* Mis routed harness.
* Rubbed through wire insulation.
* Broken wire inside the insulation.

Check for the following conditions:
* Poor connection at PCM-Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
* Damaged harness-Inspect the wiring harness for damage. If the harness appears to be OK, observe the APP sensor 1 display on the Tech 2 while moving connectors and wiring harnesses related to the sensor.

A change in the display will indicate the location of the fault. If DTC P1275 cannot be duplicated, the information included in the Failure Records data can be useful in determined vehicle mileage since the DTC was last set.

If it is determined that the DTC occurs intermittently, performing the DTC P1275 Diagnostic Chart may isolate the cause of the fault.

Error code 1159 told by the dealer it needs a part that cost over $500


The 3.0L and 3.5L engines in the XG300, XG350 and Santa Fe incorporate a Variable Induction System (VIS). The VIS is a secondary set of throttle plates in the upper intake plenum used to increase low end torque while maintaining high rpm performance. The Powertrain Control Module (PCM) uses a Variable Intake Motor (VIM) to control the opening and closing of the additional throttle plates called the Intake Control Valve (ICV).
At low rpm the (ICV) is closed and, as rpm increases, it is opened a specified amount for optimum airflow.
A VIS system condition is not likely to affect drivability, however, a diagnostic trouble code (DTC) may set. The DTC for the VIS system is P1159 (Variable Intake Target Position). The PCM controls the desired valve position and when the feedback of the
valve position does not correlate with the requested position this code is set. This DTC will not turn the check engine lamp on, however the code will remain in memory.
NOTE: P1159 has been changed to P2015 for the 2005MY.
Please refer to DTC P2015 in the 2005 Shop Manual for further diagnostic information on P1159. (XG350: page FL-555) (Santa Fe: page FL-633)
DTC DETECTING CONDITION:
ITEM DETECTING CONDITION POSSIBLE CAUSE
DTC Strategy Target position monitoring • Poor connection
• Open or short to battery
in harness
• VIS Motor or VIS Motor
Rotation Sensor
• PCM
Enable Condition Engine speed > 3750 rpm
Threshold Value Unable to obtain target value
Diagnosis Time Unable to obtain target position 4 times
MIL On Condition N/A

The VIM is not available as a separate unit from the upper plenum if replacement is needed, therefore the entire plenum assembly must be replaced.
NOTE: With the intake plenum removed, inspect the gear on the VIM to see if it has stripped. Carefully inspect the throttle plate retaining screws that attach the plates to the VIS shaft. If any of the screws are missing (2 screws per throttle plate) inspect for engine damage.
Once the intake replacement is completed (see appropriate Shop Manual for the vehicle you are working on) the Electronic Throttle Position System (ETS) should be re-initialized by turing the ignition key On and Off within 1 second. Then, wait 30 seconds before starting the vehicle. Refer to TSB 05-36-002 for the complete ETS
initialization procedure.

Air Conditioner for Benz 1998 E320


Check system for codes;

Displaying & Reading Trouble Codes (DTC Memory)
Air Conditioning (A/C) 

Models 208 as of MY 1998

Diagnostic trouble Code Memory [15] 

Note: 
  • The A/C pushbutton control module (N22) has DTC memory and data output. The diagnostic trouble codes and data are displayed via the temperature display window. The stored DTC's will remain in memory even with the vehicle battery disconnected.
  • The DTC memory differentiates between current and intermittent faults.
  • Numerous DTC's can also be read with the Hand-Held Tester (HHT).

Preparations for DTC Readout 

  1. Review 11, 12, 13, 14, 15, 21, 22, 31, 31, 41
  2. Ignition: ON
  3. Temperature selector: left: "HI"; right: "LO"
  4. Ignition: OFF
  5. Ignition: ON
  6. Within 20 seconds press REST and EC simultaneously for more than 5 seconds.
  7. The LED in Recirculated Air flashes and the display shows "d1A".
  8. Press AUTO repeatedly until all DTC's are displayed. Record each DTC as it is displayed.
  9. Each fault (short circuit, open circuit) is assigned a DTC. Thus in the left display: "E1" appears, and the right display indicates the DTC. The current faults (refer to table) are displayed first, next, the intermittant failures (e.g. 45 °5) are displayed in the display window next to the FAN symbol. By pressing the right AUTO the next DTC is displayed.
  10. To erase: Can only be performed after all faults have been readout. Press left AUTO and right AUTO buttons simultaneously for more than 2 seconds and the display shows: left: "d" and right: "FF". To cancel erase: By pressing the left AUTO button, the current faults will appear again.
  11. Select a base temperature setting.
  12. Turn ignition OFF, to end test.
Note: Due to instrument cluster (IC) series interface, DTC's may be stored in IC memory, therefore readout and erase DTC's from IC memory.
