Chevrolet Trax Manifold Absolute Pressure (MAP) Sensor Guide: 2013-2021
Solve poor performance and check engine lights on your 1.4L Turbo Trax by understanding and replacing your MAP sensor.
- A bad MAP sensor on a Trax causes hesitation, rough idle, poor fuel economy, and a Check Engine Light (P0106, P0107).
- Replacement is very easy for a DIYer, requiring only a T20 Torx driver and taking less than 15 minutes.
- Premium aftermarket brands like ACDelco, Bosch, and Delphi offer OEM-level quality and are recommended for this repair.
- Before replacing, check for vacuum leaks, as they can cause similar symptoms and trigger the same fault codes.
Is Your Trax MAP Sensor Failing?
A bad MAP sensor can cause a range of noticeable problems in your Chevrolet Trax. Because it sends incorrect pressure readings to the engine's computer, the air-fuel mixture becomes unbalanced. This can lead to a frustrating driving experience and potential engine harm if ignored. The most common alert is an illuminated Check Engine Light, but you should also watch for other specific symptoms.
Choosing the Right Aftermarket MAP Sensor
You don't need to go to a dealership for a quality replacement part. Reputable aftermarket brands offer an excellent balance of reliability and value. The key is to choose a brand known for quality electronics.
Premium / OEM-Equivalent Brands:
- ACDelco: As GM's official parts supplier, ACDelco offers both "Original Equipment" parts (identical to the factory part) and high-quality professional-grade aftermarket sensors. They are a top-tier choice for fit and performance.
- Bosch & Delphi: These companies are major global manufacturers of original parts for many car brands, including GM. A sensor from Bosch or Delphi is often made to the same standards as the original and is considered a premium replacement.
- NGK/NTK: While famous for spark plugs, NGK's sensor division (NTK) is highly respected and produces reliable, OE-quality sensors.
Trusted Aftermarket Brands:
- Standard Motor Products (Standard Ignition): SMP is a well-regarded aftermarket manufacturer that produces a wide range of sensors engineered for durability and precision.
- Spectra: Known for fuel system and engine management components, Spectra offers a reliable mid-range option.
- Walker Products: This brand provides a broad catalog of engine sensors that offer a good mix of quality and affordability.
Economy Brands:
- Brands like Facet, Global Parts, True Tech, and Vemo fall into the budget-friendly category. While they offer significant cost savings, their long-term reliability and calibration precision may not match that of premium brands. They can be a viable option for a quick fix or if budget is the primary concern.

Known Issues, Recalls, and Service Bulletins
Searches for official recalls on the 2013-2021 Chevrolet Trax did not find any specific to the MAP sensor itself. However, a Technical Service Bulletin (TSB), #17-NA-221, addresses issues like loss of power, hesitation, and smoke from the exhaust in extremely cold weather (-18°C / 0°F or less). This condition can be caused by ice building up in the charge air cooler (CAC), which can affect the pressure readings and may trigger MAP sensor-related fault codes like P0236, P2227, and P0299. 🎬 Watch: Troubleshooting turbo boost sensor and P0236 codes The procedure involves inspecting the turbocharger air pressure sensor (a related component) for contamination.
Frequently Asked Questions
What does the P0106 code mean on my Chevy Trax?
The P0106 trouble code indicates a "Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance" problem. This means the signal from the MAP sensor is not what the engine computer expects to see based on other sensors. It can be caused by a faulty sensor, a vacuum leak, or a wiring issue. Codes P0107 (circuit low) and P0108 (circuit high) also point directly to MAP sensor issues.
🎬 Watch: How to fix P0106 and P0107 fault codesWhere is the MAP sensor located on the 1.4L Trax engine?
The MAP sensor is mounted directly on the intake manifold, located on the backside of the engine. It is held in place by a single T20 Torx screw and has a single electrical connector, making it relatively easy to access and replace.
🎬 See this step-by-step MAP sensor replacement walkthroughCan I clean the MAP sensor instead of replacing it?
While some sensors like the Mass Air Flow (MAF) sensor can be cleaned, it is generally not recommended for the MAP sensor on the Trax, especially if it's contaminated due to the issues described in TSB #17-NA-221. The official GM bulletin advises against using chemical cleaners or compressed air. Given the low cost of a replacement and the sensor's sensitivity, replacing it is the most reliable repair.
Is an ACDelco aftermarket part the same as the original GM part?
Not always, but the quality is GM-approved. ACDelco offers different tiers. "ACDelco GM Original Equipment" is the exact part your Trax was built with. "ACDelco Gold" (formerly Professional) parts are high-quality aftermarket parts that meet GM's standards. For a critical sensor, either line is a trustworthy choice.
