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.
You likely won't notice any drivability problems.
- ECT voltage intermittently greater than 4.8 volts.
- ECT sensor intermittently indicates ECT at less than
