ECT Signal Circuit Shorted to Voltage
The P0118 code can be caused by the Engine Coolant Temperature (ECT) Signal Circuit Shorted to Voltage. This means the ECT sensor is not sending the proper signals to the Powertrain Control Module (PCM). When this happens, the ECT sensor must be replaced to restore proper functioning.
ECT Signal Circuit Open/High Resistance
The P0118 code can also be caused by the ECT Signal Circuit Open/High Resistance. This means the ECT sensor is not sending the proper signals to the PCM due to an open or high resistance. When this happens, it is necessary to replace the PCM to address the problem properly.
Sensor Ground Circuit Open/High Resistance
The P0118 code can also be caused by the Sensor Ground Circuit Open/High Resistance. This means the wiring and connectors are not sending the proper signals to the PCM. When this happens, it is necessary to check and repair the wiring and connectors in order to address the problem properly.
Engine Coolant Temperature (ECT) Sensor
The P0118 code can also be caused by the Engine Coolant Temperature (ECT) Sensor. This means the ECT sensor is not sending the proper signals to the PCM. When this happens, it is necessary to replace the ECT sensor to properly address the problem.
