Air Charge Temperature Sensor Replacement Service

What is the Air Charge Temperature Sensor all about?

Air is essential to engine operation. In fact, your engine is really just a giant pump designed to suck in as much air as possible. This air is mixed with fuel vapors (atomized gasoline) and then ignited. Without the right mix of air and fuel, the ignition will be off (too rich or too lean). A number of factors must be taken into account where airflow is concerned, including density, volume and temperature.

The air charge temperature sensor is mounted to your intake, and works in tandem with other sensors to ensure that the car’s computer has the right information necessary to adjust the air/fuel ratio appropriately for the demands of the driver. Really, the air charge temperature sensor just measures the temperature of the incoming air. Warm air is less dense, while cool air is denser. This gives the computer the data necessary to adjust the mixture to provide the right performance.

Over time, the air charge temperature sensor is exposed to high heat levels from the engine, and it will eventually fail through normal wear and tear.

Keep in mind:

  • The air charge temperature sensor is not part of any maintenance inspection.
  • The sensor mounts to the manifold, where temperatures are very high, so we don’t recommend attempting to replace it yourself.
  • A failing air charge temperature sensor will trigger the Check Engine light.

How it's done:

  • The air charge temperature sensor is verified to see if it needs to be replaced
  • The defective air charge temp sensor is removed
  • The new air charge temp sensor is installed
  • The air charge temp sensor is tested for operation
  • The vehicle is tested to ensure proper operation of the air charge temp sensor

Our recommendation:

The air charge temperature sensor is just one of several essential components that ensures your engine is able to operate correctly and provide the performance you need. Over time, it can wear and fail. If that happens, you can expect to see poor engine performance, and the Check Engine light will come on. If you suspect the air charge temperature sensor has failed or is failing, have one of our expert mechanics inspect and replace the sensor if required.

What common symptoms indicate you may need to replace the Air Charge Temperature Sensor?

  • Check Engine light is on
  • The engine idles rough
  • Lean/rich operation

How important is this service?

Without the necessary information about air volume, density and temperature, your car’s computer cannot determine the right air/fuel mixture. As a result, you could see either lean or rich operation, both of which can damage the engine. Replace a faulty air charge temperature sensor as soon as possible.

People say the nicest things

Jason is knowledgable, reliable and friendly person. He took his time to explain things about my car. I highly recommend YourMechanic and Jason's service.

I can't say enough about how pleased I am that I found YourMechanic and Raul. I'm from out of town and didn't know who to contact to fix a truck I was borrowing. I searched the web and found YourMechanic.....thank goodness. I found Raul to be professional, an outstanding mechanic and the price was more than fair.

A++ Highly recommended! Bryce was very professional, knowledgeable and punctual. He explained to me in detail exactly what he did and showed me the parts he replaced. I will definitely be booking Bryce for my next appointment.
