ECT 1

ECT 1 is installed in the heater manifold, at the rear of the right-hand (RH) cylinder head. The input from this sensor is used in calibration tables and by other systems.

If there is an ECT 1 fault, the engine control module (ECM) adopts an estimated coolant temperature. On the second consecutive trip with an ECT 1 fault, the engine control module (ECM) illuminates the malfunction indicator lamp (MIL).
