29 Accelerator pedal position sensor (APPS)

Accelerator pedal position sensor Diagnosis
The purpose of the diagnosis shall be the detection of electrical faults and not plausible Conditions of the two sensors. Therefore the following error-checks are performed:
- Signal range check high
- Signal range check low
- Ratio check
- Double error

Flowchart: Out of Range / Rationality check






Flowchart: Double error
