Checks to be carried out if fault is present
Short circuit to positive
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | ignition on; engine ECU, disconnected, downstream oxygen sensor 1351 connected: - check: no voltage on terminal(s) 86 (88V.NR) ignition on; engine ECU, disconnected, downstream oxygen sensor 1350 disconnected: - ignition off: - check the resistance R - downstream oxygen sensor 1351, R between 3 and 5 Ω |
Short circuit to earth
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | ignition off, engine ECU, disconnected, check: - no earth at terminal(s) 86 on the 88 V.NR connector (1320) |
Open circuit
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | ignition on, engine ECU, connected: check: presence of 12 V at terminal 86 on control unit 88V.NR (computer) ignition off: - check the resistance R of the sensor (between terminals 1 and 2), R between 3 and 5 Ω |
