What parts do I need for my air charge temperature sensor replacement and how much do those parts cost?

You can check your owner’s manual or ask your mechanic for precise parts, but here’s a general rundown of the requirements for an air charge temperature sensor replacement:

Air charge temperature sensor: Your air charge temperature sensor—also known as a manifold air temperature sensor (MAT) or intel air temperature sensor (IAT)—is located in your vehicle’s intake system and identifies the temperature of incoming air. Air charge temperature sensors typically cost $20 to $65.

Dielectric grease: Dielectric grease is usually applied to the air charge temperature sensor connector to decrease the likelihood of corrosion or moisture buildup. Dielectric grease costs $7 to $30 on average.

Socket set and wrench: Your air charge temperature sensor is mounted in the intake system with bolts and screws, which will need to be removed with sockets or wrenches. Socket sets cost $30 to $90, while wrenches cost upwards of $10.

Should I buy OEM or aftermarket parts?

If your air charge temperature sensor needs to be replaced, you should opt for an OEM replacement part. Your air charge temperature sensor is an integral part of your engine’s combustion process, so you’ll need a replacement part that perfectly suits your vehicle and is built with the correct materials.

Aftermarket air charge temperature sensors are typically cheaper than OEM replacements, but OEM parts typically include warranties and they last much longer on average.

Where can I buy parts for my air charge temperature sensor replacement?

You can purchase a new air charge temperature sensor from your vehicle’s manufacturer or from an auto parts shop like AutoZone. OEM and aftermarket parts are both available online from third-party sellers, and you can typically find replacements on Amazon and eBay.

Pro tip: Check your vehicle’s owner's manual or consult with a mechanic for replacement specs, which you can use to find the correct parts.

How will a mechanic replace my air charge temperature sensor?

An air charge temperature sensor replacement requires the right tools, protective gear, and a fair understanding of car engines. The process will vary depending on the vehicle, but your mechanic will generally follow these steps for a successful replacement:

Preparation: Your mechanic will park your vehicle on a flat surface in the shop and turn off the engine. They will also apply the hand brake, disconnect the battery, and wait for the engine to cool down.

Locate the sensor: The air charge temperature sensor or IAT sensor is usually located in or near the air intake system with the intake manifold. Your mechanic will use your vehicle’s owner’s manual or an online guide to locate your sensor.

Disconnect the electrical connector: Your mechanic will disconnect the air charge temperature sensor’s electrical connector.

Remove the old sensor: With a wrench or socket, your mechanic will carefully release the old air charge temperature sensor from its position on or in the intake system.

Install the new sensor: Placing it in the correct position, your mechanic will push or screw in the new air charge temperature sensor.

Reconnect the electrical connector: Your mechanic will reconnect the electrical connector to the new air charge temperature sensor. In some vehicles, the electrical connector may slide or click into place.

What happens if I don’t replace my air charge temperature sensor?

If you notice any symptoms of a faulty air charge temperature sensor, don’t wait to get an inspection. A failing air charge temperature sensor can result in the following issues:

Lower engine performance

Difficulty starting the engine

Engine overheating

Engine knocking

Incorrect engine control unit (ECU) air-to-fuel adjustment

Decreased fuel efficiency

Higher emissions

What is an air charge temperature sensor?

The air charge temperature sensor—not to be confused with an air filter or air cleaner temperature sensor—is an important part of a healthy engine. As its name indicates, the air charge temperature sensor tests the temperature of air that is entering the engine for combustion. This is one of the multiple sensors that helps your car’s computer regulate the combustion process.

Since air changes density at different temperatures (warm air is less dense than cool air), this sensor helps your car adjust the mixture of air and fuel that will power your engine.

When should I replace the air charge temperature sensor on my car?

The most common signs of a bad air charge temperature sensor include:

Check engine light: Your check engine light will turn on if your onboard diagnostic system or ECU detects an issue related to the sensor.

Lower engine performance: A faulty air charge temperature sensor can result in decreased power from your engine, rough idling, hesitation during acceleration, and lower fuel economy.

Lower fuel efficiency: A faulty air charge temperature sensor can lead to an incorrect air/fuel mixture, which will increase your car’s fuel consumption and lower your car’s fuel economy. Take your vehicle to an automotive mechanic immediately if you suspect your IAT sensor is affecting your engine's fuel management.

Higher emissions: If your engine runs too rich or too lean due to a malfunctioning air charge temperature sensor, your vehicle’s emissions will increase. A failed emissions test, smoke from the exhaust, or strange smells may result from a bad IAT.

Issues starting: If your air charge temperature sensor is malfunctioning, you may encounter issues with starting your car, especially in cold temperatures.

Visible damage: Cracks or corrosion on your air charge temperature sensor can cause it to malfunction. Visually inspect your sensor for signs of wear on a regular basis.

How often should an air charge temperature sensor be replaced?

Your air charge temperature sensor is an electrical component that is constantly exposed to extremely high temperatures within the engine. On average, an air charge temperature sensor lasts five years.

Keep in mind: Your air charge temperature sensor is not usually inspected during regular maintenance, so you need to watch out for your “check engine light” or other signs of a deteriorating IAT.

Can I replace my air charge temperature sensor myself?

Due to the extreme heat where this sensor is mounted, it would be dangerous to try and replace this part yourself. Rather than attempting to DIY this replacement, you should take your vehicle to a certified mechanic who can correctly handle and install your new air charge temperature sensor.

How much does it cost to replace an intake air temperature sensor?

On average, it costs $136 to replace an air intake temperature sensor. This price includes $33 for parts and $103 for labor costs.

What happens when an air charge temperature sensor goes bad?

If your air charge temperature sensor goes bad, you could experience any of the following symptoms:

Decreased fuel efficiency

Lower engine power

Rough idling

Issues starting your vehicle

Higher emissions

Engine overheating

Is the air charge temperature sensor important?

The air charge temperature sensor in your vehicle is an important component in relation to the engine’s combustion process. This sensor measures the temperature of the air that enters your engine for combustion, and it helps your car’s engine control module (ECM/ECU) or powertrain control module (PCM) adjust the air-fuel ratio that powers your engine.

Can you drive with a broken temperature sensor?

You should not drive with a broken temperature sensor. If your air charge temperature sensor is faulty, driving your vehicle can lead to false temperature readings and the following problems:

Lower engine performance

Engine damage

Engine overheating

Engine knocking

Decreased fuel efficiency

Higher emissions
