Overview
| CODE | REASON | EFFECT |
| Fault Code: 2185 PID: S232 FMI: 3/3 LAMP: Amber SRT: |
Sensor Supply Voltage 4 Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at +5 volt sensor supply circuit to the accelerator pedal position sensor. |
Engine will only idle. |
 Accelerator Pedal or Lever Position Sensor Supply Voltage Circuit
|
Circuit Description
The electronic control module (ECM) supplies the accelerator pedal or lever position sensor with +5 volts.
Component Location
The accelerator pedal or lever assembly is located in the cab.
Shop Talk
This fault is logged when the ECM senses more than +5.25 volts on the accelerator pedal or lever position +5 volt supply line. This can be caused by a short circuit to a voltage source in the OEM harness or a short circuit to an actuator signal circuit that is greater than +5 volts.
