Chevrolet Aveo Manifold Absolute Pressure (MAP) Sensor Guide for 2004-2012 Models
Fix your Aveo's rough idle, poor gas mileage, and hesitation by choosing the right replacement MAP sensor.
- A faulty MAP sensor is a common cause of a rough idle, poor gas mileage, and a Check Engine Light with codes P0106, P0107, or P0108 on a 2004-2012 Aveo.
- Replacement is a simple, 15-minute DIY job for most owners, requiring only basic tools.
- High-quality aftermarket brands like Bosch or Delphi offer OEM-level reliability for a lower price.
- Do not try to clean a MAP sensor; it is a sealed electronic part that must be replaced if faulty.
Symptoms of a Failing MAP Sensor in a Chevrolet Aveo
When the MAP sensor on your Aveo starts to fail, it sends incorrect information to the engine's computer. This can cause a variety of noticeable problems. You can't tell if the sensor is bad just by looking at it; diagnosis is required. However, watch out for these common symptoms:
- Check Engine Light: A failing MAP sensor will almost always trigger the Check Engine Light. You may see diagnostic trouble codes (DTCs) like P0106, P0107, or P0108. 🎬 See how to diagnose these specific MAP sensor error codes.
- Rough Idle: Your car may shake or idle unevenly when stopped.
- Poor Fuel Economy: A bad sensor can trick the computer into using too much fuel, causing you to visit the gas station more often.
- Hesitation and Lack of Power: The car might feel sluggish or delay its response when you press the gas pedal.
- Black Smoke from Exhaust: If the engine runs too rich (too much fuel), unburnt fuel can exit through the exhaust as black smoke.
- Failed Emissions Test: Incorrect air-fuel mixture often leads to higher emissions, which can cause you to fail a smog check.
Choosing the Right Aftermarket MAP Sensor
For a critical electronic part like a MAP sensor, brand quality matters. While an OEM ACDelco part is a safe bet, several aftermarket brands offer excellent quality, often because they are the original manufacturer for GM. Aftermarket parts can provide the same performance for a lower price.
Brand Quality Tiers for Chevrolet Aveo
- Top Tier (OEM Equivalents): Brands like Bosch, Delphi, and NGK/NTK are often the original equipment manufacturers for car companies. Choosing one of these brands is the closest you can get to OEM quality and ensures proper calibration and longevity. Delphi, once part of GM, is a highly reputable choice.
- Mid-Tier (Reliable Aftermarket): Brands like Standard Ignition (SMP) and Walker Products have a long history of producing reliable aftermarket components. They offer a good balance of quality and price and are a solid choice for most repairs.
- Economy Tier (Budget-Friendly): Brands like Global Parts, True Tech, and other private labels offer the lowest price. While tempting, be aware that the quality and calibration of these sensors can be inconsistent. For a sensor this critical to engine performance, it's often worth spending a little more for a trusted brand to avoid future problems.
Typical Replacement Costs
The cost to replace a MAP sensor on a 2004-2012 Aveo can vary. The part itself is affordable, and the labor is minimal due to its easy accessibility.

Frequently Asked Questions
Where is the MAP sensor on a 2004-2012 Chevy Aveo?
The MAP sensor is located on the intake manifold, between the throttle body and the engine head. 🎬 Watch this video to see the exact MAP sensor location. It is a small, black plastic sensor with an electrical connector and is typically held in place by one bolt.
Can I just clean my Aveo's MAP sensor?
No, you should not attempt to clean a MAP sensor. Unlike a Mass Airflow (MAF) sensor, which can sometimes be cleaned, MAP sensors are sealed units. Using chemical cleaners or compressed air can damage their sensitive internal components. If a MAP sensor is faulty, it must be replaced.
What do the common MAP sensor codes (P0106, P0107, P0108) mean?
These codes point to a problem with the MAP sensor's circuit. P0106 means the sensor's reading is out of the expected range or performance. P0107 indicates the sensor's circuit voltage is too low, and P0108 means the voltage is too high. While these codes strongly suggest a bad sensor, they can also be caused by wiring issues or major vacuum leaks.
Is an OEM ACDelco sensor better than an aftermarket one for my Aveo?
ACDelco is GM's official parts brand and guarantees a perfect fit and function. However, top-tier aftermarket brands like Bosch and Delphi often manufacture the original parts for GM. For the Aveo, a sensor from one of these reputable aftermarket brands will provide comparable performance and reliability at a better price.
Are there any recalls for the Aveo MAP sensor?
A search of the National Highway Traffic Safety Administration (NHTSA) database did not show any specific recalls for the Manifold Absolute Pressure sensor on the 2004-2012 Chevrolet Aveo. However, some GM vehicles have had service bulletins (TSBs) related to MAP sensor issues, such as icing in cold weather or faulty sensors causing error codes, though these were not specific to the Aveo.
