[2] Check component Sensor in component B37 (Accelerator pedal sensor).: Open circuit in wiring / Short circuit to ground

Test 1: Check component B37 (Accelerator pedal sensor). Sensor 1

1. Check component B37 (Accelerator pedal sensor). Sensor 1
Check actual value B37 (Accelerator pedal sensor). Sensor 1
Test prerequisite

- Switch on ignition.
Status of relevant actual value:
- Pedal value sensor Sensor 1:Warning! Communication with ECU required.
Specified value

- Accelerator pedal not depressed = 0 %
- Accelerator pedal depressed fully = 100 %
Question:

- Is the actual value o.k.?


YES
The actual value is okay.Possible cause and remedy

- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose contact and corrosion..
End of test

NO
Check power supply of component B37 (Accelerator pedal sensor). Sensor 1
Figure legend

- B37 (Accelerator pedal sensor)
Test prerequisite

- The actual value is not o.k.
Test sequence

- Switch off ignition.
- Detach coupling at component B37 (Accelerator pedal sensor).
- Measure direct voltage with multimeter between sockets (B37x1) 6 and (B37x1) 1
- Switch on ignition.
Specified value

- Voltage[4.6...5.1] V
Question

- Is the measurement value OK?







YES
The measurement value is OK.Possible cause and remedy

- Test lead to pin 5 for short circuit and open circuit.
- Component B37 (Accelerator pedal sensor) is defective.
End of test

NO
The measurement value is not OK.Possible cause and remedy

- Test signal line between components N3/9 (CDI control unit) and B37 (Accelerator pedal sensor) for Short circuit to ground.
- 5 V Voltage supply interrupted
