Description
ECT SENSOR CIRCUIT INTERMITTENT HIGH VOLTAGE
Engine Coolant Temperature (ECT) sensor is a thermistor, that
varies resistance based on temperature. As temperature of sensor
increases, resistance decreases. High temperature will result in a low
signal voltage. DTC will set when PCM sees an ECT sensor voltage
intermittently greater than 4.8 volts.
Symptoms
You likely won't notice any drivability problems.

intermittently greater than 4.8 volts.
Symptoms
You likely won't notice any drivability problems.
Causes
- ECT voltage intermittently greater than 4.8 volts.
- ECT sensor intermittently indicates ECT at less than
-29F (-34C).
- If DTC P0118 is also set, diagnose DTC P0118 before
proceeding. - Check for faulty connections or damaged harness.
- Replace ECT sensor
