Not specified (short circuit to earth or short circuit to positive or open circuit)
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | check: ignition on, ECU connected: - no voltage at terminal(s) 15, 18 of connector 55V.NR warning: if 12 V is present for 2/3 seconds after switching on the ignition, short circuit with a function supplied by +ve after relay engine running: - 0.1 V ≤ U peak ≤ 1 V (when accelerating fiercely) between terminals 15 and 18 of the control unit connector 55V.NR engine running, for a steady engine speed of less than 5000 rpm: - 0.1 V ≤ U peak ≤ 0.3 V between terminals 15 and 18 of the control unit connector 55V.NR - fastening and condition of the sensor |
