Where is the fuel temperature sensor located?
The Fuel Temp Sensor is located on the driver’s side fuel rail, near the Cylinder 2 fuel injector. Its mounting position in the fuel rail is sealed.
What is the engine coolant temperature sensor?
The Coolant Temperature Sensor is used to measure the temperature of the engine coolant. The readings from this sensor are then fed back to the engine control unit (ECU). This data from the sensor is then used to adjust the fuel injection and ignition timing.
How do I fix code P0118?
What repairs can fix the P0118 code?
- Repairing or replacing the ECT connector.
- Repairing or replacing the wiring open circuit as necessary.
- Replacing the ECT with a new sensor.
What are the symptoms of a faulty fuel temperature sensor?
BAD FUEL TEMPERATURE SENSOR SYMPTOMS
- YOU SENSE POOR FUEL ECONOMY.
- YOU READ IRREGULAR TEMPERATURE READINGS.
- YOU OBSERVE BLACK SMOKE COMING OFF THE EXHAUST.
- THE ENGINE STARTS TO OVERHEAT.
- THE CHECK ENGINE LIGHT TURNS ON.
Can a temperature sensor cause a car not to start?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
Can I drive with code P0118?
What Does Code P0118 Mean? Repair Urgency: Fix this code immediately to avoid serious engine damage. Diagnosis: This trouble code will put your vehicle into a failsafe mode, which may cause your car’s engine to hesitate and run rough.
Can low coolant cause P0118?
By far the most probable cause of an engine code P0118 is a defective engine coolant temperature sensor.
How do you know if you have a faulty coolant sensor?
If your vehicle starts to use a lot more gasoline than usual, or black smoke is starting to come from the exhaust pipe, these are indicators that the coolant temperature sensor in your vehicle could be defective, and needs to be replaced.
How do you test a coolant sensor?
Submerge the sensor in the water and take a reading. Wait a minute or so for the screen to give you a reading of the cold water. Once you have a reading, write down the measurement for reference. A common reading for a temperature sensor in cold water is around 5 volts.
What causes a P0118 code?
Code P0118 is the result of the ECT sensor indicating a high voltage input from the coolant temperature circuit (typically over 4.7V).
Can I drive with a P0118?
What does circuit high mean?
This is an overview. The Engine Coolant Temperature Circuit – High Input malfunction is the code for the onboard diagnostic (OBD). When the coolant temperature is low, the resistance of the sensor will be high, and when it is high, the resistance will be low.
