Starts and idles, no accelerator response.


Your Denali has Throttle Actuator Control (TAC) System - Electronic throttle control ! Are there any messages on the driver information center ? Reduced engine power ?
Reduced Engine Power Mode When the PCM detects a condition with the TAC system the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
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 motor and the throttle will return to the spring loaded default position.


?€¢
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.


You need to have it checked for DTC'S - diagnostic trouble codes , probably a accelerator pedal position (APP) sensor or TPS - throttle position sensor !

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

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.

2003 Dodge Ram 2500 5.7 Hemi, Red lighting bolt on lower right of dash comes on. When this happens the motor will not pick up speed from standing start till you press the gas pedal on down, then it revs...


Hi, if you don't have a manual, you can get a free download here: http://www.dodge.com/en/owners/manuals/

The lightning bolt indicates a fault in the electronic throttle control. It is likely the rheostat/potentiometer in the accelerator position sensor is dirty or worn out. I have pasted info on the part below from autozone.com. If you replace the sensor, be sure to follow the calibration procedure at the end of the installation instructions. Please let me know if you have any questions and thanks for using FixYa.


Operation
The Accelerator Pedal Position Sensor (APPS) assembly is located under the vehicle battery tray. A cable connects the assembly to the accelerator pedal. A plastic cover with a movable door is used to cover the assembly.


NOTE The APPS is used only with the 5.7L V-8 engine.

The Accelerator Pedal Position Sensor (APPS) is a linear potentiometer. It provides the Powertrain Control Module (PCM) with a DC voltage signal proportional to the angle, or position of the accelerator pedal. The APPS signal is translated (along with other sensors) to place the throttle plate (within the throttle body) to a pre-determined position.
A mechanical cable is used between the accelerator pedal and the APPS assembly. Although a cable is used between the pedal and APPS, a mechanical cable is not used at the throttle body. Throttle plate position is electrically determined.

Removal & Installation
The APPS is serviced (replaced) as one assembly including the sensor, plastic housing and cable. The APPS assembly is located under the vehicle battery tray. Access to APPS is gained from over top of left / front tire.

  1. Disconnect negative battery cable at battery.
  2. Disconnect APPS cable at accelerator pedal.
  3. Remove wheel house liner at left / front wheel.
  4. Gain access to APPS electrical connector by opening swing-down door.
  5. Disconnect electrical connector.
  6. Remove 3 mounting bolts.
  7. Remove APPS assembly from battery tray.
  8. If cable is to be separated at APPS, unsnap cable clip from ball socket. Release cable from plastic housing by pressing on small cable release tab.

To Install:
  1. Install Accelerator Pedal Position Sensor (APPS) cable to accelerator pedal. Refer to Accelerator Pedal Removal / Installation.
  2. Connect electrical connector to APPS.
  3. If necessary, connect cable to APPS lever ball socket (snaps on).
  4. Snap APPS cable cover closed.
  5. Position APPS assembly to bottom of battery tray and install 3 bolts.
  6. Install wheelhouse liner.
  7. The 5.7L V-8 engine is equipped with a fully electronic accelerator pedal position sensor. If equipped with a 5.7L, also perform the following 3 steps:
    1. Connect negative battery cable to battery.
    2. Turn ignition switch ON, but do not crank engine.
    3. Leave ignition switch ON for a minimum of 10 seconds. This will allow PCM to learn electrical parameters.
      NOTE The DRB III Scan Tool may also be used to learn electrical parameters. Go to the Miscellaneous menu, and then select ETC Learn.

  8. If the previous step is not performed, a Diagnostic Trouble Code (DTC) will be set.
  9. If necessary, use a proper scan tool to erase any Diagnostic Trouble Codes (DTCs) from PCM.
