Low voltage detected at remote accelerator position signal pin. |
Engine can possibly not respond to remote accelerator input. |
 Remote Accelerator Position Sensor Circuit
|
Circuit Description
The remote accelerator pedal provides the driver’s accelerator command to the electronic control module (ECM) through the OEM harness and the OEM interface harness. The ECM uses this signal to determine the fueling command.
Component Location
The remote accelerator pedal location varies with each OEM. Use the OEM troubleshooting and repair manual.
Shop Talk
The accelerator position sensor is a potentiometer. The accelerator position sensor resistance specifications are:
- Between supply and return = 2000 to 3000 ohms
- Between supply and signal: Released = 1500 to 3000 ohms, depressed = 200 to 1500 ohms.
The remote accelerator enable switch must be turned on for the remote accelerator to operate. Possible causes of this fault code include an open circuit in the return wire, short circuit to +5 VDC or +12 VDC, defective remote accelerator position sensor, or a failed ECM power supply.
