P1116 Fault Code: Understanding The Causes And Solutions
The P1116 fault code indicates that the Engine Coolant Temperature (ECT) sensor is reporting a temperature that is outside of the expected range during the self-test. The ECT sensor is a thermistor device that measures the temperature of the engine coolant.
It works by changing its resistance based on the temperature. The ECT sensor is a passive sensor, meaning it is connected to a voltage divider network. The varying resistance of the sensor causes a change in the total current flow, which in turn affects the voltage signal sent to the Powertrain Control Module (PCM).
The PCM uses the ECT input for fuel control and cooling fan control. If the ECT sensor is reporting a temperature that is outside of the expected range during the self-test, it can lead to issues with fuel control and cooling fan operation. To fix the P1116 fault code, the ECT sensor should be inspected and tested for proper operation.
If necessary, the sensor should be replaced to ensure accurate temperature readings and proper engine performance.
FAQ
If you’re experiencing an engine light on or a service engine soon warning light, along with engine overheating, it could be due to fault code P1116.
