Where is the cooling fan sensor located?
Usually, the location of the coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath of the air intake pipe.
Where is my temperature sensor 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 happens when a coolant sensor goes bad?
If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. This will reduce fuel economy, and may hinder engine performance.
What are the symptoms of a bad temperature coolant sensor?
Symptoms of a Bad Coolant Temperature 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 much does it cost to replace temperature sensor?
The average price for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 while parts are between $66 and $88.
Is there a fuse for coolant temperature sensor?
There isn’t one per se. There will be a fused wire with voltage to the instrument cluster (your owners manual should indicate which fuse), but the temperature sensor is providing a variable “resistance to ground,” which the temperature gauge in the dash is reflecting.
Can you drive with a faulty coolant temperature sensor?
It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicles coolant sensor is a critical component used by the engine management system. It directly effects, cooling and fueling of the engine and therefore effects how the engine performs.
Where is the connector on a Cavalier radiator fan?
Inspect the fuse in the fuse relay box. Start the engine and pull the connector off the ECT. This is a two-wire connector with a yellow and a black wire. It is located near the coolant outlet on the upper rear of the hose. When the connector is pulled off of the ECT, within a second or two the fan should come on.
Where is the ECT on a Cavalier radiator?
It is located near the coolant outlet on the upper rear of the hose. When the connector is pulled off of the ECT, within a second or two the fan should come on. If it does come on, the ECT is suspect. Check the voltage with the meter by backprobing the sensor when the engine warms up.
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.
Where is the coolant temperature sensor on a car?
The engine coolant temperature sensor (also known as the coolant temperature sending unit) is a small sensor screwed into the thermostat housing. The sensor measures the temperature of the coolant and relays that information to the temperature gauge on the dash.
What to do if temperature gauge on Cavalier no longer works?
If the temperature gauge in the dash of your Chevrolet Cavalier no longer works, you may have to replace this sensor. Disconnect the ground cable from the negative battery terminal. Loosen the retaining bolt using a wrench, then pull the clamp off the terminal.
Where is the coolant sending unit on a car?
It will be located between the upper radiator hose and the engine. Detach the electrical connector from the coolant temperature sending unit by pulling it off. The sending unit will be screwed into the thermostat housing. Unscrew the sending unit from the thermostat using a wrench.
