Engine Coolant Temperature Circuit Range/Performance Problem
COMMON FAILURES:
DTC P0116, 117, 118, 125 - Engine Coolant Temp Sensor (ECT) out of range
This set of codes is almost always accompanied by a report of overheating. The most common cause is water pump failure (see Photo 1). Start by looking for obvious coolant leaks, low coolant level or other signs of overheating. Certainly check the ECT for resistance values; replace if it's out of specification. If the coolant level is low, determine the source of leakage (see Photo 2) and repair. If there are symptoms of high engine heat when driving, but the temperature is OK at idle, the most likely candidate is the water pump.
