Possible cause:
B37 (Accelerator pedal sensor)
Affected functions:
Engine diagnosis
Engine output
Test 1: Check component B37 (Accelerator pedal sensor).
1. Check component B37 (Accelerator pedal sensor).
Test 1.1: Check component B37 (Accelerator pedal sensor) using actual value.
Test 1.2: Check power supply of component B37 (Accelerator pedal sensor).
1.1. Check component B37 (Accelerator pedal sensor) using actual value.
Test sequence
Switch on ignition.
Status of the relevant actual values:
Idle speed detection:Warning!
Full load detection:Warning!
B37 (Pedal value sensor) Voltage 1:Warning! Communication with ECU required.
B37 (Pedal value sensor) Voltage 2:Warning! Communication with ECU required.
Specified values
Accelerator pedal position:Idle speed
B37 (Accelerator pedal sensor)Signal1 : [0.2...0.5] V
B37 (Accelerator pedal sensor)Signal2 : [0.1...0.5] V
Accelerator pedal position:Kickdown
B37 (Accelerator pedal sensor)Signal1 : [4.3...4.8] V
B37 (Accelerator pedal sensor)Signal2 : [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
Check power supply of component B37 (Accelerator pedal sensor).
Check lines from component N3/10 (MESFI [ME] control unit) to component B37 (Accelerator pedal sensor).
B37 (Accelerator pedal sensor)
1.2. Check power supply of component B37 (Accelerator pedal sensor).

Connection A of test cable 108 may NOT be connected to connection B of the 126pin socket box (050).
Test prerequisite
The actual value is not o.k.
The power supply of component N3/10 (MESFI [ME] control unit) is OK.
Test sequence
Switch off ignition.
Connect socket box (126pin) to component N3/10 (MESFI [ME] control unit).
Measure direct voltage with multimeter between sockets [F.10] 106 and [F.23] 119 of the 126pole socket box tester.
Measure direct voltage with multimeter between sockets [F.11] 107 and [F.23] 119 of the 126pole socket box tester.
Switch on ignition.
Specified value
Voltage[4.75...5.25] V
Question
