This sensor is responsible for monitoring the temperature of the coolant in the vehicle's engine. When the sensor detects that the coolant temperature is too high, it sends a signal to the engine control module (ECM) to adjust various engine parameters to prevent overheating and potential damage.
Common Causes of P1118 Scion
- Faulty coolant temperature sensor.
- Wiring or connector issues in the coolant temperature sensor circuit.
- Coolant level too low or contaminated.
- ECM malfunction.
- Cooling system malfunction.
Symptoms of P1118 Scion
- Check engine light illuminated on the dashboard.
- Engine running hotter than normal.
- Poor fuel economy.
- Engine misfires or rough idling.
