sensor: between the two heads, at the

connector: on the sensor.
With engine off: closed circuit (continu-
ity).
With engine on: open circuit (infinite re-
sistance).
Check the sensor connector and the instrument panel connector (PIN 17): If not OK, restore.
If OK, check the continuity of the purple cable between the sensor connector and the in-
strument panel connector PIN 11: if not OK, restore the cable harness; if OK, replace the
sensor
Disconnect the sensor connector and check the ground insulation of the purple cable: if there
is continuity with the ground connection, restore the cable harness; if earth insulated, replace
the switch. if the error remains, check oil pressure in the engine circuit with a pressure gauge
