Pedal Position Sensor Circuit. Plausibility Fault Between Circuit 1 and 2.







Fault symptom
- Check Engine
- Performance loss.

On-board diagnosis

Type of diagnosis:
- Continuous

Enable criteria:
- When the ECM is awake, diagnosis is active (even with the ignition off).

Fault criteria:
- When the voltage difference between pedal position sensor 1 and 2 is 5.2 - 8.2% depending on pedal position (5.2% released pedal, 8.2% fully engaged pedal).

Dependent:
- None

System reaction to a fault:
- Limp home

OK report:
- Fault criterion not fulfilled and vehicle speed over 0 km/h for more than 60 s.

Fault handling:
Type III
(See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
