7.2.9. Sensor of temperature of cooling liquid (ECT sensor)


The arrangement eats - the sensor on 4-cylinder engines


The arrangement eats - the sensor on 6-cylinder engines



Eats - the sensor represents the thermoresistor which resistance increases at fall of temperature.

Check

PERFORMANCE ORDER
1. For check disconnect the socket from the sensor and check the sensor resistance which has to be 2500–3000 Ohms at 20 °C.
2. Having warmed up the engine, or having removed the sensor and having placed in boiled water, check sensor resistance at 80 °C which has to be 250–300 Ohms.

Replacement

PERFORMANCE ORDER
1. Switch off ignition.
2. On the cold engine merge 3–4 l of liquid.
3. Turn out the sensor. At installation wrap up the new sensor a teflon tape and turn, observing extreme care.

Prevention

Breakage of the ECT sensor because of maloperation will break normal work of all power supply system of the engine.
