Remote Accelerator Pedal or Lever Position Sensor 1 Circuit – Voltage Above Normal, or shorted to High Source
|Fault Code: 133
Remote Accelerator Pedal or Lever Position Sensor 1 Circuit – Voltage Above Normal, or shorted to High Source. High voltage detected at remote accelerator pedal position circuit.
Remote accelerator will not operate. Remote accelerator position will be set to zero percent.
Remote Accelerator Pedal Position Sensor Circuit
The remote accelerator pedal or lever provides the operators accelerator command to the electronic control module (ECM) through the OEM harness. The ECM uses this signal to determine the fueling command.
The remote accelerator pedal or lever location varies with each OEM. Refer to the OEM troubleshooting and repair 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.
Possible causes of this fault include:
- Remote accelerator pedal or lever position signal circuit shorted to battery or +5 volt supply
- Open remote accelerator pedal or lever return circuit in the harness or connections
- Remote accelerator supply shorted to battery
- Failed remote accelerator pedal or lever position sensor.
Note: The three wires in the remote accelerator position sensor circuit must be twisted together.
