B37 (Accelerator Pedal Sensor)

B37 (Accelerator Pedal Sensor)

Check Component B37 (Accelerator Pedal Sensor).

Test 1 Check Actual Value B37 (Accelerator Pedal Sensor)
Test 2 Test Voltage Supply of Component B37 (Accelerator Pedal Sensor).


1 Check Actual Value B37 (Accelerator Pedal Sensor)

Test sequence
- Switch on ignition.

Status of the relevant actual values:
- B37 (Accelerator pedal sensor) Voltage 1: Note! Communication with ECU required
- B37 (Accelerator pedal sensor) Voltage 2: Note! Communication with ECU required

Specified values
- B37 (Accelerator pedal sensor) Voltage 1 (Accelerator pedal position: Idle speed): [0.2...0.5] V
- B37 (Accelerator pedal sensor) Voltage 2 (Accelerator pedal position: Idle speed): [0.1...0.5] V
- B37 (Accelerator pedal sensor) Voltage 1 (Accelerator pedal position: Kickdown): [4.3...4.8] V
- B37 (Accelerator pedal sensor) Voltage 2 (Accelerator pedal position: Kickdown): [2.1...2.5] V

Question
- Are the actual values o.k.?
Yes
The actual values are okay. ** End of Test **
No
The actual values are not okay.
Possible cause and remedy
- Test voltage supply of component B37 (Accelerator pedal sensor).
- Inspect cables from component N3/10 (ME-SFI control module) to component B37 (Accelerator pedal sensor).
- B37 (Accelerator pedal sensor)

** End of Test **
