Action in service
- When not under current the two sensors must provide the following voltage values: S1: 0.86 V (+/- 0.3 V), S2: 4.14 V (+/- 0.3 V)
- Check wires to throttle-valve sensors
- Check valve for sticking and contamination
- Visual examination of plug contacts (at components, wiring harness and DME),
- Component malfunction unlikely, only replace throttle valve in response to emergency
