DTC P0116 for the 2.8L, 3.0L, 3.2L, or 3.6L engine
Circuit / System Description
The engine coolant temperature (ECT) sensor is a variable resistor that measures the temperature of the engine coolant. The engine control module (ECM) supplies 5?V to the ECT signal circuit and supplies a ground to the low reference circuit. The ECM monitors the mutual performance of the ECT and the intake air temperature (IAT) signals. The ECM monitors the warm up and cool down behavior of the sensors, after a vehicle has been driven at operating temperature and then is shut down. If the ECM detects that the ECT is not with in a predetermined range of IAT after a long soak (over night) or the ECT and IAT are not within a range of each other as compared to a previous cold start, this DTC sets.
