Where is the temperature sensor on a 2005?

Find the coolant temperature sensor on the front of the engine block, just behind the alternator. Pull upward on the locking tab on the coolant temperature sensor’s wiring harness, and pull the wiring harness from the sensor.

Where is the engine coolant 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.

How do I know if my coolant temperature sensor is working?

Connect the black lead of the meter to the body of the cold sensor and the red to the terminal. You should have a reading of approximately 2000 ohms. Check the warm sensor in your engine. You should see a much lower reading on the ohm meter.

Where is the temperature sensor on a 2006 Ford Focus?

The sensor is located in the head between the 2nd and 3rd sparkplug. Finally, if you pull a trouble code P0128, this simply means that the computer is getting a lower than expected motor temp reading.

How much does it cost to fix coolant sensor?

The Best in Auto Repair The average cost for engine coolant temperature sensor replacement is between $134 and $155. Labor costs are estimated between $83 and $105 while parts are priced at $51.

How can I test the coolant temperature sensor?

Testing the ECT/CHT sensor Resistance: One way is to measure the resistance of the sensor at different engine temperatures and compare the readings to the specifications listed in the service manual. Measuring the resistance of the Engine coolant temperature (ECT) sensor.

Where is the coolant temperature sensor on a trailblazer?

Raise the TrailBlazer off the jack stands, using a floor jack, and remove the jack stands. Lower the SUV to the ground. Find the coolant temperature sensor on the front of the engine block, just behind the alternator. Pull upward on the locking tab on the coolant temperature sensor’s wiring harness, and pull the wiring harness from the sensor.

How does the cylinder head temperature sensor work?

Some cars use a cylinder head temperature or CHT sensor instead of, or in addition to the ECT sensor. The CHT sensor (see the photo) works the same way, but it measures the temperature of the cylinder head metal and is not immersed in coolant. This allows the CHT sensor to measure the temperature of the engine correctly even with loss of coolant.

How do I tighten the coolant sealer on my car?

Allow the sealer to cure for the time specified by its instructions. Hand-tighten the new coolant temperature sensor into the engine and tighten it to 15 foot-pounds, using a torque wrench, 6-inch extension and 12-point socket. Plug the wiring harness into the receptacle on the new sensor.

How does coolant temperature sensor affect engine performance?

A bad engine coolant temperature sensor affects engine performance: It may cause a constant lean air/fuel mixture, causing the engine to stall or idle rough. Or it may cause a constant rich air/fuel mixture, causing an increase in emissions and fuel consumption.

What does a bad coolant temperature sensor do?

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.

What are the symptoms of a bad coolant temperature sensor?

Another symptom of a problem with the coolant temperature sensor is an overheating engine. The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.

Where do I find the coolant temperature sensor?

What is a Coolant Temperature Sensor and How Does It Work? 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.
