Fault description
Diagnosis monitors throttle valve adaptation.
The voltage value of the two throttle valve sensors aren't in the valid range (sensor 1: 0.5 V +/- 0.3 V; sensor 2: 4.5 V +/- 0.3 V) in the lower mechanical limit position (throttle valve not completely closed).
Possible fault cause:
- Throttle valve 2 impaired by soiling
- Wiring harness between DME and throttle valve actuator motor 2 defective
- Throttle valve 2 defective
