Guide to the Manifold Absolute Pressure (MAP) Sensor for 2007-2011 Chevrolet Cheyenne
Understand the common failure symptoms of the MAP sensor on your truck and how to choose the right aftermarket replacement.
- A bad MAP sensor on your Cheyenne will typically cause a check engine light with codes P0106, P0107, or P0108, along with poor performance and bad gas mileage.
- Replacement is extremely easy and can be done in under 30 minutes with basic tools, making it a great DIY repair.
- For best results, choose a quality aftermarket brand like NGK/NTK or Standard Ignition, as these trucks are sensitive to sensor accuracy.
- No recalls have been issued for the MAP sensor on this vehicle, but be aware of potential icing issues in extreme cold, which may not require sensor replacement.
Is Your Cheyenne Running Rough? It Could Be the MAP Sensor.
If your 2007-2011 Cheyenne is idling poorly, getting bad gas mileage, or hesitating when you accelerate, a failing Manifold Absolute Pressure (MAP) sensor could be the problem. This small but important sensor directly affects your engine's air-fuel mixture. When it sends incorrect information to the truck's computer, you will notice a drop in performance and fuel economy.
Symptoms of a Bad MAP Sensor
- Check Engine Light: This is often the first sign. Common trouble codes include P0106, P0107, and P0108.
- Poor Fuel Economy: An incorrect reading can cause the engine to use more fuel than necessary.
- Rough Idle: The engine may shake or sound unstable when you're stopped.
- Lack of Power: You might notice your truck feels sluggish or hesitates when you press the gas pedal.
- Black Smoke from Exhaust: This can happen if the sensor causes the engine to run too rich (too much fuel).
- Failed Emissions Test: Incorrect air-fuel mixture will lead to higher emissions.
Choosing the Right Aftermarket MAP Sensor
When replacing the MAP sensor on your Cheyenne, you have several aftermarket options. Since the truck's computer is sensitive to the sensor's readings, choosing a quality part is important. Here’s a breakdown of the available brands:
- Premium Brands (NGK, Standard Ignition): NGK (also known as NTK for sensors) is a highly respected original equipment (OE) supplier known for quality and reliability. Standard Ignition (Standard Motor Products) is a long-standing aftermarket brand that produces parts meeting or exceeding OE standards. These brands are your best bet for a hassle-free repair that lasts.
- Standard Brands (Spectra): Spectra Premium is a common aftermarket brand. However, some user reviews indicate potential issues with fit and quality control on their sensors, so it may be a bit of a gamble.
- Economy Brands (Global Parts, True Tech): These brands are typically the most affordable. While they may function, their long-term reliability and accuracy can be questionable compared to premium options. For a critical sensor like the MAP, it's often better to invest in a more reputable brand.
Known Issues: Icing in Cold Climates
General Motors has issued Technical Service Bulletins (TSBs) for similar Silverado/Sierra models regarding the MAP sensor. In very cold temperatures, ice can form on the sensor during long drives, causing a P0106 code and a "Reduced Engine Power" message. The issue often resolves itself once the engine heat melts the ice. GM notes that this doesn't mean the sensor is faulty and that a winter grille cover can help prevent it.

Frequently Asked Questions
Where is the MAP sensor located on my 2007-2011 Cheyenne?
The MAP sensor is located on the top of the intake manifold, usually toward the back near the firewall, just behind the throttle body. It's easily accessible after removing the plastic engine cover.
Is it hard to replace the MAP sensor myself?
No, this is a very easy DIY job. It involves removing the engine cover, disconnecting a wire, removing a small clip or bolt, and pulling the sensor out. The entire process usually takes less than 30 minutes.
Do I need to reset the computer after replacing the MAP sensor?
It's a good idea. After replacing the sensor, you can clear the trouble codes with a basic OBD-II scanner. If you don't have a scanner, disconnecting the battery's negative terminal for about 30 minutes will also reset the computer and clear the check engine light.
What's the difference between a MAP and a MAF sensor?
Your truck has both. The MAP (Manifold Absolute Pressure) sensor measures air pressure in the intake manifold. The MAF (Mass Air Flow) sensor measures the amount and density of the air entering the engine. Both sensors help the computer create the right air-fuel mixture, but they measure different things.
