Where are temperature sensors located?

The Engine Coolant Temperature Sensor can be located in a few places, depending on the vehicle and its manufacturer. 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.

What causes a P0118 code?

The onboard diagnostic (OBD) code P0118 is an Engine Coolant Temperature Circuit – High Input malfunction. When the engine has been running for more than a few minutes and the ECT is reading a less than freezing temperature, the PCM thinks there is a circuit fault and sets the P0118 code.

Can a bad thermostat cause a P0118 code?

There are several key causes that can cause a P0118 trouble code to populate on your OBD-II scanner. The first is that your engine coolant level is low. This can also be caused by a faulty Engine Coolant Temperature (ECT) sensor or problems with the engine coolant thermostat.

How do you fix trouble code P0118?

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.

Where are the sensors located in a 2005 Dodge Neon?

Locate the inlet air temperature (IAT) sensor on the air duct for the air box. It measures the temperature of the outside air. Find the knock sensor near the front of the starter, on the engine block. This sensor tells the computer about the vibrations inside the engine and allows the computer to adjust the mixture to prevent pinging.

Where is the coolant temperature sensor located on an engine?

The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.

Can a bad coolant sensor cause a car to not start?

Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.

How much does it cost to replace a coolant temperature sensor?

Unscrew the ECT sensor in an anticlockwise direction, similar to how a spark plug is removed. Install the new sensor and reconnect the connector cable. The average replacement cost of the Coolant Temperature Sensor is between $100 and $220. The labour cost is between $40 and $140 while the part itself costs between $50 and $80.
