Code P0118 2006 Scion xB Description
The P0118 code for a 2006 Scion xB indicates a problem with the Engine Coolant Temperature (ECT) sensor circuit, specifically a high input signal. The ECT sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM). When the ECM receives a high input signal from the ECT sensor, it means that the engine coolant temperature is higher than expected.
Common Causes of P0118 2006 Scion xB
- Faulty ECT sensor
- Corroded or damaged wiring in the ECT sensor circuit
- Faulty ECM
- Coolant leak leading to inaccurate temperature readings
- Air pockets in the cooling system
Symptoms of P0118 2006 Scion xB
- Engine running hot
- Engine overheating
- Poor fuel economy
- Rough idling
- Check Engine Light illuminated
How to Fix P0118 2006 Scion xB
- Begin by diagnosing the issue using a scan tool to read the code and check the ECT sensor data.
- Inspect the ECT sensor and its wiring for any visible signs of damage or corrosion.
- Test the ECT sensor's resistance and voltage to determine if it is functioning properly.
- Check the cooling system for leaks and ensure it is properly filled with coolant.
- If the ECT sensor is faulty, replace it with a new sensor and clear the code from the ECM.
Cost to Fix P0118 2006 Scion xB
The cost of repairing a P0118 code in a 2006 Scion xB can vary depending on the specific cause of the issue and the labor rates in your area.
