The ECT sensor is responsible for measuring the temperature of the engine coolant and sending this information to the engine control module (ECM). When the ECM detects that the ECT sensor reading is above the normal operating range, it triggers the P0118 code. This can lead to issues with fuel efficiency, emissions, and overall engine performance.
Common Causes of P0118 2002 Nissan Sentra
- Faulty ECT sensor
- Corrosion or damage to the ECT sensor wiring
- Issues with the ECM
- Coolant leaks or low coolant levels
- Cooling system problems, such as a stuck thermostat
Symptoms of P0118 2002 Nissan Sentra
- Engine overheating or running hot
