Chevrolet Malibu Intake Manifold Temperature Sensor Guide for 2016-2023 Models
Address rough idling, poor fuel economy, and check engine lights on your 2016-2023 Malibu by understanding this critical sensor.
- On the 2016-2023 Malibu, this sensor is often integrated with the MAP sensor into one part.
- Symptoms of failure include a Check Engine Light (P0113), rough idle, poor acceleration, and bad gas mileage.
- Replacement is a very easy DIY job that takes less than 30 minutes with basic tools.
- There are no recalls for this sensor, but a TSB exists for cold-weather intake issues on 2016-2018 models.
Is your 2016-2023 Malibu running rough or losing power?
A failing Intake Manifold Temperature Sensor can cause a surprising number of engine problems, from poor gas mileage to a constant Check Engine Light. This sensor sends vital information to your engine's computer. When it fails, the computer can't create the right air-fuel mixture, leading to noticeable issues. Fortunately, this is a straightforward and affordable part to replace for most DIY mechanics.
Symptoms of a Bad Intake Temperature Sensor
When this sensor starts to fail, your Malibu will let you know. Here are the most common signs:
- Check Engine Light: This is often the first warning. A code scan will typically reveal codes like P0111, P0112, or P0113. 🎬 Watch: How to fix these specific temperature sensor trouble codes.
- Poor Engine Performance: You might experience a rough or uneven idle, hesitation when you press the gas pedal, or a general lack of acceleration. In some cases, the engine may be hard to start, especially when cold.
- Reduced Fuel Economy: If the computer receives incorrect temperature data, it may command the engine to run too rich (using too much fuel) or too lean, hurting your gas mileage.
- Failed Emissions Test: An improper air-fuel ratio can lead to increased emissions, causing you to fail a smog check.
Known Issue: Cold Weather Problems (2016-2018)
A Technical Service Bulletin (TSB) was issued for some 2016-2018 Malibu models with the 1.5L engine. In extremely cold weather (-18°C / 0°F or colder), moisture in the charge air cooler (CAC) system could freeze, causing reduced power and setting trouble codes like P0299. While not a direct failure of the temperature sensor itself, it's a related intake system problem with similar symptoms. The fix involves installing a winter grille cover and potentially replacing the CAC.
Choosing the Right Aftermarket Part
When replacing the intake temperature sensor, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. For a simple sensor like this, a quality aftermarket part offers a great balance of performance and value.
- OEM (ACDelco): This is the same part your car was built with. It guarantees a perfect fit and function but typically costs more.
- Aftermarket (Standard Ignition): Brands like Standard Ignition (also known as Standard Motor Products) specialize in producing parts that meet or exceed OEM specifications. They are a trusted choice for professional mechanics and offer reliable performance at a more budget-friendly price. For this specific sensor, Standard Ignition provides a dependable, direct-fit replacement.
Pro Tip: On the 2016-2023 Malibu, this sensor is often integrated with the Manifold Absolute Pressure (MAP) sensor. Always verify the OEM part number or use a VIN lookup to ensure you are ordering the correct combined sensor for your specific engine.

Frequently Asked Questions
Can I drive my Malibu with a bad intake temperature sensor?
Yes, but it's not recommended for long. The car will run poorly, get bad gas mileage, and could potentially cause long-term damage to other components like the catalytic converter due to the incorrect air-fuel mixture.
Is this a difficult part to replace myself?
No, this is a very easy DIY job for a beginner. The sensor is typically located on the intake manifold, held in by one or two screws, and has a simple electrical connector. The replacement should take less than 30 minutes with basic tools.
🎬 Follow this step-by-step walkthrough to replace the sensor yourself.Are there any recalls for this part on the 2016-2023 Malibu?
No. While there have been recalls for other issues on these model years, there are no active recalls from the NHTSA specifically for the intake manifold temperature sensor.
What tools do I need to replace the sensor?
You will likely only need a small socket set or a Torx (star-shaped) bit screwdriver to remove the screws holding the sensor in place. A flat-head screwdriver can be helpful for releasing the clip on the electrical connector.
Will a dirty engine air filter cause the same problem?
Yes, a severely clogged air filter can restrict airflow and cause symptoms similar to a bad sensor. It's always a good practice to check the condition of your air filter before replacing sensors.
