Throttle Position Sensor Circuit, Plausibility Fault between Circuit 1 and 2







Fault symptom
- Check Engine
- Cruise control not working.
- Limp home

On-board diagnosis

Type of diagnosis:
- Continuous

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

- NONE of the following DTCs must be detected:
- P0122, P0123, P0222, P0223

Fault criteria:
- When the difference in voltage between throttle position sensors 1 and 2 is 4 - 8%, depending on the position of the throttle (4% for unactuated pedal, 8% for fully depressed pedal).

Dependent:
- None

System reaction to a fault:
- Correction of mass air flow/combustion for fuel calculation is blocked.
- Limited acceleration and idle function.
- Cruise control blocked.
- Secondary air switched off.

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.
