- DTC P0116 is designed to detect a ECT sensor that is skewed high.
- An IAT sensor that is skewed low could cause this DTC to set.
- When checking ECT sensor, the Engine Coolant Temperature Sensor Resistance table should be used in order to determine if a skewed sensor is the problem. See ENGINE COOLANT TEMPERATURE SENSOR RESISTANCE table.
