Checks to be carried out if fault is present
Coherence
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running starting phase engine speed sensor signal 1313 inconsistent, between terminals 48 and 49 of the 55 V.NR connector | ignition on, control unit 1320 disconnected, operate the starter, check: - the voltage varies from 4 V to 9 V between terminals 48/49 on the 55 V.NR connector ignition off, control unit 1320 disconnected, sensor disconnected (1313): - check the continuity of the line, terminals 24, 48, 49 of connector 55 V.NR - sensor resistance value(s) 300 ≤ R ≤ 400 Ω check the condition of the toothed wheel and the sensor electrode |
