Checks to be carried out if fault is present
High stop
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running, after an operating time specified in calibration: high stop | verify: - absence of air leaks - ignition system - the sparking plugs - fuel pressure - for the oxygen sensor heating - fouling of injectors - condition of the purge canister solenoid valve - the condition of the air filter engine running, verify: - 0.1 ≤ U ≤ 1 volts between ECU terminals 28 and 10 |
Low stop
