Details of the Chrysler p0116 OBD Code
Chrysler fault code P0116 relates to engine coolant temperature sensor circuit range/performance issues.
Code P0116 for Chrysler vehicles indicates that the Engine Coolant Temperature (ECT) sensor circuit is reading a voltage signal that is out of the normal range.
This sensor is responsible for providing the Engine Control Module (ECM) with data on the engine’s coolant temperature.
When the ECM detects a voltage signal that is too high or too low from the ECT sensor, it triggers code P0116. The ECT sensor is typically located near the thermostat housing or on the cylinder head.
It is a thermistor that changes resistance based on the temperature of the coolant.
The ECM uses this information to adjust fuel delivery and ignition timing for optimal engine performance and emissions control.
When troubleshooting code P0116, technicians commonly check the ECT sensor for proper operation, wiring harness for any damage or corrosion, and the connector for a secure connection.
Replacing a faulty ECT sensor or repairing a damaged wiring harness usually resolves this issue.
