First check for power and grounds at the sensor. Check for voltage at the signal wire, and continuity on the signal wire bt the sensor and the ecu. if all your circuits are OK then replace the sensor.

05 mustang gt codes po 2104 and 2112 replace tcm and tps


P2104 - Throttle Actuator Control (TAC) System - Forced Idle Description: The TAC system is in the failure mode effects management (FMEM) mode of forced idle. Possible Causes:
  • Open or short in multiple accelerator pedal position (APP) sensor circuits.
  • Damaged APP sensor.
  • Damaged powertrain control module (PCM).
Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first. Application Key On Engine Off Key On Engine Running Continuous Memory All

P2112 - Throttle Actuator Control (TAC) System - Stuck Closed. Description: This powertrain control module (PCM) fault status indicates the throttle plate is at a lower angle than commanded. Possible Causes:
  • Binding throttle body, stuck closed.
  • Damaged PCM.
Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV1 Are you familiar with electronic throttle control ? You have a dc electric motor on the throttle body an at the gas pedal there are APP pedal position sensors that send voltage signals to the PCM which in turn controls the electric motor opening an closing the throttle ! By what this P02112 states the throttle plate is binding , which means it could be bad or just needs to be cleaned ! You will need to disconnect the electrical connector an see if it is binding by pushing it with finger or thumb . which is ever easiest !

How do I solve for My Hyundai sonata model 2009 code P2110 , P2118 in scaning. I changed throttle body and TP sensor. after change of these even I am getting problem in accelerator not increases above


P2110...Faulty Throttle Actuator Control Module
- Throttle Actuator Control Module harness is open or shorted
- Throttle Actuator Control Module circuit poor electrical connection

P2118 - Electronic Throttle Control(ETC) system is made of the components throttle body, Throttle Position Sensor(TPS)1&2 and Accelerator Position Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle properly in response to the driving condition.

Getting trouble code 106. What is solution for correcting this problem. Thank you. 2005 crossfire.


Chrysler codes,. only.

p0106,

on newer Chysler, cars they have many codes with 106, leaving out the prefix is bad idea.

Like U0102

or C0106?

P0106 is MAP performance failure. (that dont mean replace it)

the puter has no IDEA what is wrong, only that tests failed.

here are the conditions.

When Monitored and Set Condition



  • When Monitored: Engine running for at least 30 seconds and no fault in the throttle valve actuator.


  • Set Condition: Low limit: The Manifold Absolute Pressure (MAP) Sensor reading is below a calculated value when the throttle valve angle is greater than 80F for approximately 5 seconds. High limit: The MAP Sensor reading is greater than a calculated value that is determined by engine speed and throttle valve angle for approximately 5 seconds.




now in gringo or bar stool.

1: the puter brain saw you go near wide open throttle and the

map sensor (vacuum sensor) do not show new zero vacuum.

even a clogged air filter could do this, causing a false high vacuum







POSSIBLE CAUSES




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT OPEN




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO GROUND




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE




5-VOLT SUPPLY CIRCUIT OPEN




5-VOLT SUPPLY CIRCUIT SHORT TO GROUND




5-VOLT SUPPLY CIRCUIT SHORT TO VOLTAGE




5-VOLT SUPPLY CIRCUIT SHORT TO SENSOR GROUND CIRCUIT




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO SENSOR GROUND CIRCUIT




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO 5-VOLT SUPPLY CIRCUIT




SENSOR GROUND CIRCUIT OPEN




ENGINE OIL SENSOR




MANIFOLD ABSOLUTE PRESSURE SENSOR




POWERTRAIN CONTROL MODULE






then the FSM goes to step by step tests. to find above reasons.

omitted. (too long )



the word low is ambiguous in all FSM.

it can mean, low plenum pressure,

or low vacuum (opposite)

and low voltage, its a pain in the xxx to find this fact out.

the map outputs high voltage for low vacuum (same as high absolute pressure)



the fsm tests are inane.

we check the voltage out of the map

at keyon

running

and wide open throttle for 1 second. just gun it and watch.

here is what it does.

left side is wide open throttle, idle is 20 inchs. key on is, WOT.

so, what is that

4.5v is keyon

start engine, get about 1.5v

the gun engine, then drop throttel to zero throttle fast

the causes,. huge vacuum about 24 inches, or 1v or less

this is a working MAP. if those tests pass.

the test (OBD2 monitor) fails for about not getting near 4vdc from MAP output pin, DOES THIS HELP?

Engine light came out and give me the code P2135


P2135 FORD Description

Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement.


The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM). In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition

My 1993 dodge dakota cranks and runs smoothly to any destination, but if i cut off the engine,it will crank but will bot restart until the engine cools(about one hour) any ideas?


Have you run a fualt code test on the systems control mofule? You may have a defective crank sensor or cam sensor, the test will give a code.
For vehicles made after 1996, retrieving the codes of the check engine light in your dash panel is simple. All you need to do is find your diagnostic connector located under the dash by the driver side. You can then hook up a scanner and the codes will be displayed for you. If you don't have any scanner like most drivers, you can bring your vehicle to any local automotive store and they will usually scan the codes FREE for you.

However, for vehicles made on or before 1995, there is only one cheap way to get it: You do it yourself!

On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check the engine light. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports.

Dodge trucks have a diagnostic trouble code retrieval method, Unlike Gm and Ford trucks the Dodge line of trucks has no data port connector to gather codes from.

Instead Dodge has a ignition cycle activation sequence that anyone can active by turning the ignition key on off in rapid succession five times with the cycle ending in the "on" position.

Once this activation has started the check engine light will start to flash. The first set of check engine light flashes will be the first digit of the two number code. After the check engine light pauses for a short time it will start to blink again starting the second digit identification and completing the code's second number. If additional trouble codes are stored in the computer the first digit will begin to flash, and then the second digit. For example: the check engine light flashes four times, pauses and then flashes three more times the code is 43.

The check engine light will flash one and then two meaning the code gathering is over. The system will only flash 12 if there are no codes stored in the computer's memory. To clear codes disconnect the negative battery terminal for 30 seconds and reconnect.

Below are the OBD DTC's for 1995-previous model year EFI-equipped Dodge vehicles.

My 2003 chevy truck goes into limp mode and pulls code PO220.Where is the tps sensor located?


Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- No throttle response Possible Causes - Harness or connector (The TP sensor circuit is open or shorted.)
- Electric Throttle Control Actuator (or Throttle Body Motor)
- Accelerator Pedal Position Sensor (APP) P0220 Description Electric Throttle Control Actuator consists of throttle control motor, throttle position (TP)sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
When is the code detected? An unexpected voltage from the TP sensor is sent to ECM.
