ENGINE COOLANT TEMPERATURE (ECT) SENSOR

1 Artificial Resin Housing

2 Metal Housing

3 NTC (Negative Temperature Coefficient)

Engine Coolant Temperature (ECT) sensor detects coolant temperature and supplies information to the ECM. It is

composed of metal housing with two NTC resistor, 4 pin connector. The ECM provides a 5 volt signal to the ECT

sensor through a dropping resistor. When the engine is cold, the ECT sensor provides high resistance, which the

ECM detects as a high signal voltage. As the engine warms up, the sensor resistance becomes lower, and the

signal voltage drops. At normal engine operating temperature, the ECT signal will measure about 1.5 to 2.0 volts.

The ECM uses information about coolant temperature to make the necessary calculations for:

Fuel delivery

Ignition control

Knock sensor system

Torque converter clutch application

Canister purge

Cooling fan operation
