Remote Accelerator Pedal or Lever Position Sensor 1 Circuit – Voltage Below Normal, or Shorted to Low Source. Low voltage detected at remote accelerator pedal position signal. |
Remote accelerator will not operate. Remote accelerator position will be set to zero percent. |
 Remote Accelerator Pedal or Lever Position Sensor Circuit
|
Circuit Description
The remote accelerator pedal or lever provides the opertors accelerator command to the electronic control module (ECM) through the OEM harness. The ECM uses this signal to determine the fueling command.
Component Location
The remote accelerator pedal or lever location varies with each OEM. Refer to the OEM service manual.

If troubleshooting an intermittent accelerator problem:
The remote accelerator pedal or lever position sensor signal voltage can be monitored with the INSITE™ electronic service tool, while flexing the harness to locate the intermittent connection. Intermittent connections will show up as abrupt changes in signal voltage displayed by INSITE™.
Possible causes of this fault include:
- Remote accelerator pedal or lever position signal shorted to engine ground or return wires in the OEM harness or sensor.
- Failed remote accelerator pedal or lever position sensor.
- Open circuit in the remote accelerator signal, supply, or return wire in the harness or connectors.
NOTE: The three wires in the remote accelerator position sensor circuit must be twisted together.
