Buick Encore Mass Air Flow Sensor Guide for 2013-2022 Models
Experiencing rough idling, poor acceleration, or bad gas mileage? Your MAF sensor might be the problem.
- A faulty MAF sensor is a common issue that triggers a Check Engine Light with a P0101 code.
- Before replacing the sensor, check for air leaks in the intake hose and try cleaning the sensor with dedicated MAF cleaner.
- Replacement is very easy for a DIYer and takes less than 15 minutes with basic tools.
- For best results, choose an OEM-equivalent brand like ACDelco, Bosch, or Delphi to avoid compatibility issues.
Symptoms of a Failing MAF Sensor in a Buick Encore
When the MAF sensor in your 2013-2022 Encore starts to fail, it sends incorrect information to the engine's computer. This can cause a variety of noticeable problems. The most common sign is the Check Engine Light illuminating on your dashboard. You will often find diagnostic trouble codes like P0101, P0171, or P0102 when you scan the vehicle.
- Rough Idle: Your Encore may shake or sound unstable when stopped.
- Hesitation and Stalling: The vehicle might stumble or jerk when you accelerate, and in some cases, it could stall completely.
- Poor Fuel Economy: A bad sensor often causes the engine to use more fuel than necessary, leading to fewer miles per gallon.
- Loss of Power: The car may feel sluggish and won't accelerate as quickly as it should.
- Black Smoke from Exhaust: This indicates the engine is running rich (too much fuel), which can be a direct result of a faulty MAF sensor.
Check for Air Leaks First
Symptoms of a bad MAF sensor can also be caused by vacuum leaks in the air intake system. A GM Technical Service Bulletin (TSB 18-NA-333) for 2018-2019 Encore models notes that a poorly installed air hose can cause a P1101 code and poor acceleration, mimicking MAF sensor failure. Always inspect the air ducts and hoses for cracks or loose connections before replacing the sensor.
Choosing the Right Aftermarket MAF Sensor
When replacing the MAF sensor on your Encore, you have several good aftermarket options that balance quality and cost. Since the sensor is a sensitive electronic part, choosing a reputable brand is important for long-term reliability.

Tier 2: Quality Aftermarket Brands
These brands provide a reliable and more affordable alternative to OEM parts without a significant compromise in quality. Forum discussions show that many owners have success with these brands, though some have reported issues with lower-cost options causing erratic engine behavior.
- Hella: A reputable brand offering quality electronic components.
- Spectra Premium: Often cited as a decent replacement, though some users have reported inconsistent performance.

Can I Just Clean the MAF Sensor?
Sometimes, the sensor's wires are just dirty from oil or dust, causing incorrect readings. You can try cleaning it with a dedicated MAF sensor cleaner spray. Do not touch the delicate sensor wires or use other chemicals like brake cleaner, as this will destroy it. Cleaning is often a good first step and can sometimes solve the problem, but if the sensor's internal electronics have failed, replacement is the only solution.
