Description:

  • The fault code P0118 indicates that there is a high input in the engine coolant temperature (ECT) circuit, indicating that the engine is running hotter than it should be. This may result in a loss of power or acceleration, poor fuel efficiency, or engine damage if not addressed.

Possible Symptoms:

  • Illuminated check engine light

  • Engine running hot or overheating

  • Decreased fuel efficiency

  • Loss of power or acceleration

  • Engine damage (if not addressed)

Possible Causes:

  • Faulty engine coolant temperature sensor

  • Short or open circuit in the engine coolant temperature sensor wiring

  • Corroded or damaged engine coolant temperature sensor connector

  • Failed engine control module (ECM)

Related Parts:

  • Engine Coolant Temperature Sensor: The coolant temperature sensor measures the temperature of the engine coolant. Problems lead to engine overheating

Possible Solutions:

  • Replace the engine coolant temperature sensor

  • Check and repair any damaged wiring or connections

  • Clean or replace the engine coolant temperature sensor connector

  • Replace the engine control module (ECM) if necessary
