Action in service
- Watch for collateral faults in initial adaptation,
- 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 the valve for contamination and sticking
- Check wires to throttle-valve sensors, visual examination of plug contacts (at components, wiring harness and DME),
- Trigger initial adaptation with tester and determine whether it detects faults, if so, repair these using test plan
- This fault does not usually make a component replacement necessary
