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, coolant temperature greater than 80 degrees C, engine speed above 2500 rpm | ignition off, engine ECU: disconnected, knock sensor: disconnected: - check continuity and insulating of wires A, B, D - condition and connection of connector 2V.NR (knock sensor) - securing of knock sensor |

|---|---|
| engine running, coolant temperature greater than 80 degrees C, engine speed above 2500 rpm | ignition off, engine ECU: disconnected, knock sensor: connected: - check: no voltage at terminal(s) 15, 18 of the control unit - check: no earth at terminal(s) 15, 18 on the 55V.NR connector ignition off, engine ECU: disconnected, knock sensor: disconnected: - check continuity of wires A, B and D - condition and connection of connector 2V.NR (knock sensor) - securing of knock sensor if correct, replace the knock sensor if the original fault is still present, replace the ECU |
