SOURCE: accelerator pedal sensor

there is no pedal sensor... there is a throttle position sensor located on the throttle body (near the MAF). Replacing it is simple and self explanatory once you locate it.

Testimonial: "I did that and when the symptoms reoccurred the repair shop said it needed the accelerator pedal sensor, which we found at a Kia dealership. So I'm confused."

2009 Chevy Silverado P2138 Accelerator Pedal Position


Circuit/System Description
The throttle actuator control (TAC) system uses two accelerator pedal position (APP) sensors to monitor the accelerator pedal position. The APP sensors 1 and 2 are located within the pedal assembly. Each sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit.
Two processors are also used to monitor the TAC system data. Both processors are located within the engine control module (ECM). Each signal circuit provides both processors with a signal voltage proportional to pedal movement. The processors share and monitor data to verify that the indicated APP calculation is correct.

DTC P0455: Evaporative Emission (EVAP) System Large Leak

The control module tests the evaporative emission (EVAP) system for a large leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the control module commands the EVAP canister purge solenoid valve OPEN and the EVAP vent solenoid valve CLOSED. This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge solenoid valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. The following table illustrates the relationship between the ON and OFF states, and the OPEN or CLOSED states of the EVAP canister purge and vent solenoid valves.

DTC P2138: Accelerator Pedal Position (APP) Sensor 1-2 Correlation
Electronic throttle control problem .
The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions:
• Accelerator pedal position sensing
• Throttle positioning to meet driver and engine demands
• Throttle position sensing
• Internal diagnostics
• Cruise control functions
• Manage TAC electrical power consumption
The TAC system includes the following components:
• The accelerator pedal position (APP) sensors
• The throttle body assembly
• The engine control module (ECM)

Accelerator Pedal Position (APP) Sensor
The accelerator pedal contains 2 individual accelerator pedal position (APP) sensors within the assembly. The APP sensors 1 and 2 are potentiometer type sensors each with 3 circuits:
• A 5-volt reference circuit
• A low reference circuit
• A signal circuit
The APP sensors are used to determine the pedal angle. The engine control module (ECM) provides each APP sensor a 5-volt reference circuit and a low reference circuit. The APP sensors provide the ECM with signal voltage proportional to the pedal movement. The APP sensor 1 signal voltage at rest position is less than 1 volt and increases to more than 4 volts as the pedal is actuated. The APP sensor 2 signal voltage at rest position is less than 0.6 volt and increases to more than 2 volts as the pedal is actuated.

Check engine light sensor


DTC P2138: Accelerator Pedal Position (APP) Sensor A/B (Throttle Position Sensor D/E) Incorrect Voltage Correlation.

Accelerator pedal position (APP) sensor A and accelerator pedal position (APP) sensor B are potentiometers, and they are installed in the engine compartment.

The APP sensors A and B are operated via the throttle cable to determine the accelerator opening value when the driver presses the accelerator pedal. The accelerator pedal opening value is converted to a signal in APP sensors A and B and transmitted to the engine control module (ECM)/powertrain control module (PCM) to compute the target position. The target position signal is then transmitted to the throttle actuator control module.

APP sensor A is for the primary control, and APP sensor B is a back-up of APP sensor A in case it malfunctions. Both sensors compare their output voltage to each other for malfunction detection.

When the voltage difference of APP sensor B is out of a fixed range for a set period of time, the ECM/PCM detects a malfunction, and a DTC is stored.

No messaage of reduced engine power ? Your vehicle has electronic throttle control . Has four position sensors , two are located in the gas pedal ,an two in the throttle body . The PCM uses these sensor to know how much to open the throttle plate ,allowing more air into the engine . How did you read this code an where did you read it's definition at ? This is not a code for your vehicle . Some time cheap code readers get them wrong .

Reduced Engine Power Mode
When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The ECM will perform the following actions:
- Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.

First of all a scan tool is need for this not a code reader, you need to view scan data after you find what code is stored in the PCM. It could have a problem with the powertrain control module, wiring, or the Accelerator Pedal Position (APP) Sensors. Here are a few codes that could set .

Error code p1271 on trailblazer


That trouble code is faulting the accelerator pedal sensor. The APP sensors are located in a TAC module mounted to the accelerator pedal bracket. There are three individual APP sensors within the TAC module. Three separate signal circuits, low reference circuits, and 5v reference circuits are used to determine the accelerator pedal position. The APP sensor signal voltages increase when the accelerator pedal is depressed.

I have a 2007 Chevy Tahoe. The engine light came on and stayed on. When checked, here is the code that appeared: TPS/PEDAL POSITION SENSOR ACKT RANGE/PERF. I am assuming the code deals with the...


If it is a code P0226 I would not consider it a safety issue.


Throttle position (TP) sensor C/accelerator pedal

position (APP) sensor ? - range/performance problem


Possible Causes: Accelerator cable adjustment, TP/APP sensor

Throttle position (TP) switch C/accelerator pedal position

(APP) switch ? - range/performance problem
Accelerator cable adjustment, TP/APP switch

This might only be an adjustment issue--make sure the throttle cable isn't so tight that the throttle cannot fully close.
If the cable is OK, it is probably the accelerator position sensor under the pedal.
There are procedures for testing the unit that I will paste below if you care to try them.

If you just want a shop to fix it, the part is about $50 and labor should only be 30 minutes.


Operation The sensor is made up of the two individual sensors within a single housing. Each sensor has a unique functionality to determine pedal position. The APP system along with the Powertrain Control Module (PCM) is used to calculate and control the amount of acceleration and deceleration through fuel injector control.


Removal & Installation

  1. Remove the driver-s side knee bolster.
  2. Push down on the small tab and disengage the electrical connector.
  3. Remove the pedal bolts and remove the pedal and sensor assembly.
  4. Installation is the reverse of removal.

Fig. APP sensor mounting
Testing

  1. Install a 3 amp fused jumper wire between the 5-volt reference terminal of the APP sensor and 5 volts. Install a jumper wire between the low reference terminal and a ground.
  2. Sweep the sensor through the entire range while monitoring the voltage between the signal terminal and the low reference terminal with a digital multimeter. The voltage should vary between 0.30-4.98 volts without any spikes or dropouts.
  3. If the voltage is not within the specified range or is erratic, replace the accelerator pedal assembly.

Slow acceleration on my used 2008 Silverado. Having to push hard on the accelerator before I can get to cruising speed. Not sure if this is due to the limits of the 4 speed automatic or what. Please help


WELL I WOULD SAY FUEL FILTER BUT IT IS IN FUEL TANK IT IS PART OF THE FUEL PUMP ASSEMBLY.CHECK THE APP SENSOR LOCATED ON TOP OF ACCELERATOR PEDAL.MAKE SURE PEDAL IS TIGHT AND MAKE SURE THE WIRE GOING TO APP SENSOR INTACT NOT LOOSE OR DAMAGED.IF ALL IS GOOD HAVE TRUCK SCANNED FOR ANY APP SENSOR CODES.CHECK TRANSMISSION FUSE ALSO.
