Diagnostic Aids
WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue and 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
- 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.
- If engine has been allowed to sit overnight, the ECT and IAT temperature should be within the calculated amount.
