A Guide to the Manifold Absolute Pressure (MAP) Sensor for the 2008-2017 Mitsubishi Lancer
Fix poor engine performance, rough idling, and bad gas mileage by understanding and replacing your Lancer's MAP sensor.
- A failing MAP sensor commonly causes a check engine light, rough idle, poor gas mileage, and hesitation.
- Replacement is extremely easy and accessible on the intake manifold, making it a great DIY job.
- There are no recalls for this part; failures are due to normal wear.
- Quality aftermarket brands like Delphi or Standard Ignition offer a reliable alternative to the more expensive OEM part.
Is Your Lancer's MAP Sensor Failing?
A bad MAP sensor can cause frustrating problems that seem vague. Because the sensor's data is critical for the air-fuel mixture, a failure often leads to noticeable driving issues. Ignoring these symptoms can lead to poor fuel economy, failed emissions tests, and a car that is unpleasant to drive.
Common Symptoms of a Bad MAP Sensor:
- Check Engine Light: This is the most common sign. The ECU will log fault codes, often P0106, P0107, or P0108.
- Rough Idle: The engine may shake or sound uneven when you're stopped.
- Poor Fuel Economy: A faulty sensor can cause the engine to run rich, using more gas than necessary.
- Hesitation or Stalling: You might notice a delay when you press the gas pedal, or the engine may stumble and cut out when coming to a stop.
- Black Smoke from Exhaust: This is a clear sign that the engine is burning too much fuel.
- Loss of Power: Your Lancer may feel sluggish and accelerate slower than usual.
Symptoms of a vacuum leak, such as a cracked hose, can be identical to a bad MAP sensor. Before replacing the sensor, it's wise to inspect all vacuum lines connected to the intake manifold for cracks or loose connections.
Choosing the Right Aftermarket MAP Sensor
You do not need to buy an expensive OEM sensor from the dealer to get your Lancer running right again. Many aftermarket brands offer quality parts that meet or exceed original specifications. However, quality can vary, so it's helpful to understand the brands available.
Brand Quality Tiers
- Premium Aftermarket (Recommended): Brands like Delphi and Standard Ignition (Standard Motor Products) have a strong reputation. Delphi is an OEM supplier for many car manufacturers and is known for quality electronics. Standard is also a well-regarded choice in the aftermarket. These brands are a reliable choice for a balance of price and quality.
- Standard Aftermarket: Brands like Walker Products and Holstein offer a good balance of value and reliability. They engineer their parts to match OE fit and function and perform extensive testing.
- Value-Oriented: Brands like Global Parts and Vemo are typically the most affordable. While they can be a good budget option, some user reviews suggest quality can be inconsistent. These are best if budget is the primary concern, but may carry a higher risk of premature failure.
