Engine sensors
Engine coolant temperature (ECT) sensor
Checking - Fig. 15

Technical Data Multi-plug colour Temperature 0°C 10°C 20°C 40°C 60°C 80°C 100°C 5750-6200 3530-4100 2350-2670 1085-1230 540-615 292-326 165-190 Green Resistance

Ensure ignition switched OFF. Disconnect ECT sensor multi-plug. Relieve residual pressure in cooling system. Remove ECT sensor from engine. Immerse ECT sensor probe in coolant of specified temperature. Check resistance between ECT sensor terminals. ECT sensor may be checked in situ if engine temperature and resistance readings are compared.

Engine speed (RPM) sensor
Checking operation - Fig. 16

Technical Data Terminals 1&2 Condition Engine cranking 4-9 V Voltage

NOTE: Disconnect injector multi-plugs before cranking tests, to avoid damage to catalytic converter(s). Ensure ignition switched OFF. Disconnect RPM sensor multi-plug. Briefly crank engine. Check voltage between RPM sensor terminals.
