SPN91 FMI4
Accelerator Pedal or Lever Position Sensor Circuit - Voltage Below Normal or Shorted to Low Source.
CODES:
Fault Code: 132
PID(P), SID(S): P091
SPN: 91
FMI: 4/4
Lamp: Red
SRT:
REASON: Accelerator Pedal or Lever Position Sensor Circuit - Voltage Below Normal or Shorted to Low Source. Low voltage detected at accelerator pedal or lever position signal circuit.
EFFECT:
Automotive: Severe derate in power output of the engine. Limp home capability only.
Marine: Severe derate in engine speed. Limp home capability only.
Circuit Description:
The accelerator pedal or lever position sensor is attached to the accelerator pedal or lever. The accelerator pedal or lever position sensor sends a signal to the electronic control module (ECM) when the accelerator pedal or lever is depressed and released. The accelerator pedal or lever position circuit contains three wires: Accelerator Pedal or Lever Position Supply, Accelerator Pedal or Lever Position Return, and Accelerator Pedal or Lever Position Signal.
Component Location:
The accelerator pedal or lever position sensor is mounted to the accelerator pedal or lever assembly.
Shop Talk:
If troubleshooting an intermittent accelerator problem:
The 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™ electronic service tool.
Possible causes of this fault include:
• Accelerator pedal or lever position signal shorted to engine ground or return wires in the OEM harness or sensor.
• Failed accelerator pedal or lever position sensor.
• Open circuit in the accelerator signal, supply, or return wire in the harness or connectors.
NOTE: The three wires in the accelerator position sensor circuit must be twisted together.
