2008 Malibu LTZ ECT sensor location

Once you get the cover off, the sensor is located towards the back of the engine on the right side (as if you’re sitting in the vehicle – passenger side for people in the States).

Where is the ECT sensor located?

The ECT sensor is located in the left of the cylinder head and is connected to the Engine Coolant Temperature Sensor. Underneath the air intake pipe and behind the right cylinder head is where the Engine Coolant Temperature Sensor is located.

Where is the temperature sensor located on a 2009 Chevy Malibu?


The coolant temperature sensor this sensor is located on the back right side of the engine.

What happens if I unplug ECT sensor?

What Happens If You Unplug The Coolant Temp Sensor? What is this? Unplugging the engine coolant sensor while the car is running will likely cause the engine to stumble and run rough. The engine light may not come on imminently, but a DTC (Diagnostic Trouble Code) will be logged in the PCM.

Where is the radiator coolant sensor located?

On most vehicles, the coolant temperature sensor (CTS) can be found somewhere near the engine thermostat, which allows it to function optimally. The tip of the CTS is probably located right next to the engine coolant.

How do I test my ECT sensor?

Where is the temperature sensor on a 2007 Chevy Malibu?

3 Answers. When looking from the front of the car with the hood opened, the coolant temperature sensor is on the back of the front head which would be on the drivers side of the car.

Why is my 2008 Chevy Malibu overheating?

The most common causes of overheating include low coolant level, a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt.

What can a faulty coolant temp sensor do?

If the coolant temperature sensor malfunctions, it can transmit a false signal to the computer. And the response of the computer may unbalance the timing and fuel calculations. It is also common for a coolant temperature sensor to fail without warning and send permanently cold signals to the computer.

Can you drive with a faulty coolant temperature sensor?

Yes, you can drive with a bad coolant temperature sensor. When the coolant temperature sensor goes bad the ECU of the car defaults to a static reading. But it is not recommended to keep driving with a bad engine coolant temperature sensor since it performs critical cooling, heating, and fuel adjustment functions.

How many coolant temperature sensors are in a car?

There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard.

How much does an ECT sensor cost?

The average cost for engine coolant temperature sensor replacement is between $392 and $427. Labor costs are estimated between $87 and $110 while parts are priced between $304 and $316.

What causes coolant temperature sensor failure?

One of the common problems is; when the sensor has a, poor connection inside or in the connector. This causes interruptions in the signal to the (PCM) and the (PCM) sets the fault. In some vehicles, symptoms of this problem show up as, erratic readings of the temperature gauge.

What does the ECT sensor control?

A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.

How much does it cost to replace a 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. Taxes and fees aren’t included in the estimate.

How long does it take to replace a coolant temperature sensor?

If you are doing it yourself it will take 4 to 5 hours. However if a skilled mechanic is doing it, it will take 2 to 3 hours only. Whether your car was running or not. If the engine of your car is running, then you will have to wait at least 1 hour before you start replacing the bad coolant temp sensor.

Can you clean a coolant temperature sensor?

How Do You Clean A Temperature Sensor? To wipe your alcohol, just apply alcohol to a small rag. wipe this cloth down and flush the temperature sensor down. Generally, washing it periodically does not have to be spotless as long as you do it frequently rather than having large amounts of accumulated material.

Can I fix a coolant temperature sensor?

While the vehicle must be parked with the computer in a static reading, faulty coolant temperature sensors can easily be driven to fix. One of the most important tools on which the engine management system sits is a vehicle’s coolant sensor.

How do I know if I need to change my coolant temperature sensor?

Locate the coolant temp sensor.



Symptoms of failure

  1. The engine quickly starts to overheat.
  2. The “check engine” light is on.
  3. There’s black smoke out of the exhaust tips.
  4. Running excessively rich causes increased emissions and poor engine operation, resulting in poor idle and engine vibration when the engine is cold.


Do you need to drain coolant to change coolant temperature sensor?

Do You Have To Drain Coolant To Replace Temp Sensor? Disconnect the cooling system from the radiator valve with a tool and drain about 2 to 3 quarts of liquid. A level just below the sensor should be extracted enough.
