How do I fix code po118?

What repairs can fix the P0118 code?

1. Repairing or replacing the ECT connector.
2. Repairing or replacing the wiring open circuit as necessary.
3. Replacing the ECT with a new sensor.

What can cause a P0118 code?

The onboard diagnostic (OBD) code P0118 is an Engine Coolant Temperature Circuit – High Input malfunction. This code refers to the engine coolant temperature (ECT) sensor. The code is also set if the PCM determines that the ECT sensor resistance is out of specification.

Where is my temperature sensor located?

It is most often located close to the thermostat of the cooling system or inside of it. The cooling system is located beneath the air intake pipe and behind the right cylinder.

How do you fix engine code P0138?

What repairs can fix the P0138 code?

1. Replacing the O2 sensor for bank 1 sensor 2.
2. Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
3. Replacing the catalyst in front of the sensor.
4. Repairing a leaking injector.

How do you test a coolant sensor?

You will search for the sensor within the engine block itself, using a drop light if you need help to see it better. Look at the front of the engine block in the middle of the pulleys. You will see a small terminal sticking out of the block with a wire lead coming from it. This is your coolant temperature sensor.

Is P0138 serious?

How Serious Is Code P0138? – Moderate. It is okay to drive a vehicle with P0138 for a short period of time, but driving with this code for an extended period of time can damage the catalytic converter(s).

How do I know if my thermostat sensor is bad?

What Signs May Signal Your Coolant Temperature Sensor May Be Failing?

1. Poor Fuel Economy.
2. Irregular Temperature Readings.
3. Black Smoke from Your Exhaust.
4. Your Engine is Overheating.
5. Your Check Engine Light is On.

What does p0118 mean on an Audi A4?

P0118: Engine Coolant Temp Sensor Circuit → High Input This code is thrown when the resistance coming from the coolant temp sensor does not change as the vehicle warms up. Audi A4 P0118 Symptoms P0118 is sometimes accompanied by noticeable symptoms.

What causes coolant code to throw in Audi A4?

Engine coolant can cause the code to throw if it gets corroded enough. So, if you find yourself in a situation where you can’t remember the last time that the coolant has been changed, it may be worth a shot to just change it and see if you get lucky. Conclusion Most of the time, P0118 is going to be caused by a bad temperature sensor.

What does p0118 mean on the coolant temperature sensor?

The Engine Coolant Temperature Sensor converts the coolant temperature into a voltage that is high when the engine is cold and low as the engine warms up. Code P0118 indicates a high voltage input from the Coolant Temperature Circuit to the PCM.
