Can coolant temp sensor cause no heat?
If the coolant temperature sensor malfunctions, it could cause your car engine to get overheated. The computer will again miscalculate the signal and cause the engine to heat up instead of cooling it down.
What happens when your coolant temperature sensor is bad?
The engine is very sensitive to wrong air-fuel mixtures at idle and this is a condition when you might notice that something is wrong with your engine coolant temperature sensor. The engine coolant temperature sensor can have a hard impact on the air-fuel mixture. A bad air-fuel mixture can also cause the engine performance to drop drastically.
Can a car have more than one coolant sensor?
Some vehicles may have more than one temperature sensors, as sometimes different sensors are used to send the signals to the dashboard and the control unit of your engine system. This is optional and a manufacturer can use only one coolant temperature sensor to send the signals to both of these desired receivers.
What should coolant temp be when engine is hot?
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.
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.
How to replace an automotive engine coolant sensor?
Once the sensor installation is complete, close the radiator drain valve and refill the system with coolant. Start the engine and allow it to heat up while adding coolant as needed. Reinstall the radiator cap once the engine is at operating temperature and recheck the system for leaks. Watch the Video!
What happens if your coolant temperature sensor is bad?
A bad engine coolant temperature sensor (CTS or ECT) can seriously disrupt the fuel system and engine operation of your car. That’s because the ECT sensor tells the Electronic Control Module (ECM—your car computer) at what temperature the engine is operating, so the computer can make some important decisions. For example:
Where is the coolant temperature sensor on a V6?
Locate the CT sensor. On most inline engine models (four or six cylinders), look for the sensor around the upper section of the engine block or around the cylinder head. On most V8 (and some V6) engines, you may find it also around the upper part of the engine or under the intake manifold.
Can a broken coolant sensor starve the engine?
A permanently open (broken circuit) coolant sensor will starve the engine of fuel. Luckily, this is a simple repair on most vehicle models. You can replace a bad CTS in your car following a few simple guidelines and precautions.
