Check the sensors output for variable resistance while moving the lever, and check the wires for shorts with an ohm meter while the engine is key off.

I changed everything on a 2007 Chevy uplander the camshaft position sensor And the purged sensor And the throttle body and still the check engine light and the reduce engine power came back on


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.
Did you have it checked for DTC's - diagnostic trouble code's related to the reduced engine power ?
All so has APP sensor gas pedal !
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.
Your best bet is take your vehicle to the dealer !

Error code light came on P1227


possible
  • Harness or connectors (The APP sensor 2 circuit is open or shorted.)
  • Accelerator pedal position sensor (Accelerator pedal position sensor 2)

    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 .
    DTC P2120: Accelerator Pedal Position (APP) Sensor 1 Circuit

    DTC P2122: Accelerator Pedal Position (APP) Sensor 1 Circuit Low Voltage

    DTC P2123: Accelerator Pedal Position (APP) Sensor 1 Circuit High Voltage

    DTC P2125: Accelerator Pedal Position (APP) Sensor 2 Circuit

    DTC P2127: Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage

    DTC P2128: Accelerator Pedal Position (APP) Sensor 2 Circuit High Voltage

    DTC P2138: Accelerator Pedal Position (APP) Sensor 1-2 Correlation

    Error code p2138


    Here is the definition. You may need to have someone check the accelerator pedal position sensor and the circuit.

    P2138 NISSAN Description The Accelerator Pedal Position (APP) sensor is installed on the upper end of the accelerator pedal assembly. The sensor detects the accelerator position and sends a signal to the Engine Control Module (ECM).
    Accelerator pedal position sensor has two sensors. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM.
    In addition, these sensors detect the opening and closing speed of the accelerator pedal and feed the voltage signals to the ECM. The ECM judges the current opening angle of the accelerator pedal from these signals and controls the throttle control motor based on these signals.
    Idle position of the accelerator pedal is determined by the ECM receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation
    such as fuel cut.

    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 these codes coming up on my 2005 Dodge Ram. 5.7 liter motor: P0406 P2096 P0137 P2299 Thank you.


    code #0406 = egr position sensor circuit high ( stuck egr valve or bad egr sensor most likely sensor )

    code #2096 = downstream fuel trim system lean ( see next code )

    code #0137 = O2 sensor bank 1 sensor 2 circuit low ( replace rear O2 sensor driver side )

    code #2299 = brake peddle position/accelerator pedal position incompatible. ( hav you been power braking this truck? ) ( brake light was on wile accelerator was being pushed )

    Code p2138


    P2138 is Throttle Pedal Position Sensor/ Switch D / E Voltage Correlation. Replace the Throttle Pedal Position Sensor/Switch.Remember to have the set code Cleared from the cars computer, this will turn off the check engine light and reset it. Good Luck and have a good XMASS.

    Throttle/Pedal Position Sensor/Switch B Circuit Range Performance


    there is no adjustment on these tps's it's a drive by wire system. If you don't know the vehicle, dont post!
    there's 2 sensors contained in the pedal sensor, and one on the throttle plate shaft, more often than not, it's the pedal sensor, and if you replaced that, it's the other one or a loose connection. did you reset the computer after replacing the pedal?
