A Guide to the Manifold Absolute Pressure Sensor for the 1993-2002 Mitsubishi Mirage
Fixing rough idle and poor performance in your Mirage starts with understanding this critical sensor.
- A bad MAP sensor on your Mirage will most commonly cause a check engine light with code P0105, a rough idle, and poor acceleration.
- Before replacing the sensor, check for simpler issues like cracked vacuum hoses, as the symptoms can be identical.
- Replacement is very easy for a DIY mechanic, typically requiring only one bolt and an electrical connector to be removed.
- For this critical part, it is highly recommended to invest in a quality aftermarket brand like Delphi or Standard Ignition to ensure accurate readings and avoid further issues.
Is Your Mirage Running Rough? It Could Be the MAP Sensor
If your 1993-2002 Mitsubishi Mirage is experiencing issues like a rough idle, poor acceleration, or bad gas mileage, a failing Manifold Absolute Pressure (MAP) sensor could be the culprit. This sensor plays a key role in how your engine runs, and when it sends bad information, performance suffers. Before you replace it, it's important to understand the symptoms and how to choose the right aftermarket part.
Symptoms of a Failing MAP Sensor
A bad MAP sensor can make your car feel sick in several ways. Because the engine's computer is getting wrong information about engine load, it can't properly balance the air and fuel mixture. Watch for these common signs:
🎬 Watch: A visual guide to common bad MAP sensor symptoms- Check Engine Light: This is often the first sign. The most common trouble code is P0105, which points directly to a problem in the MAP sensor circuit. 🎬 See how to troubleshoot and fix the P0105 circuit code
- Rough or Shaky Idle: The engine may struggle to hold a steady RPM at a stop, sometimes feeling like it's about to stall.
- Poor Acceleration and Hesitation: Your Mirage might feel sluggish or hesitate when you press the gas pedal.
- Bad Fuel Economy: If the sensor causes the engine to run rich (too much fuel), you'll notice you're filling up the tank more often.
- Black Smoke from Exhaust: This is a clear sign of an engine running too rich, which can be caused by a faulty MAP sensor telling the computer the engine is under more load than it really is.
Rule Out Other Issues First
Symptoms of a bad MAP sensor can be similar to other problems, like a vacuum leak from a cracked hose. Always check for obvious vacuum leaks before replacing the sensor, as this is a common and cheaper fix.

Not all aftermarket parts are created equal, and for a critical sensor like the MAP, quality matters. Using a cheap, low-quality sensor can cause persistent performance problems that are hard to diagnose. Aftermarket brands for your Mirage can be grouped into tiers:
- Premium Aftermarket (Recommended): Brands like Delphi and Standard Ignition (Standard Motor Products) have a strong reputation for producing reliable sensors that perform like the original factory part. Spending a little more on one of these brands is a smart investment for long-term reliability.
- Standard Aftermarket: Brands such as Walker Products, Spectra, and Holstein offer a balance between price and quality. They are a step up from economy parts and are often a suitable choice for daily drivers.
- Economy Brands: The lowest-priced options, including some store brands like Global Parts, can be tempting. However, they have a higher risk of being inaccurate out of the box or failing early. This can lead to continued frustration and the need to do the job twice.
Pro Tip: For a sensor this important to engine performance, choosing a brand from the Premium tier like Delphi or Standard Ignition is highly recommended to avoid future headaches.
How Much Does a MAP Sensor Replacement Cost?
The cost can vary widely based on the brand of the part and labor rates. The part itself is easy to replace, so DIY is a great option to save money.

Frequently Asked Questions
Where is the MAP sensor located on a 1993-2002 Mitsubishi Mirage?
The MAP sensor is typically located directly on the intake manifold or very close to it, attached by one or two bolts and an electrical connector. It's a small, black plastic sensor that is usually easy to access.
Can I clean my MAP sensor?
While some sensors can be cleaned, MAP sensors are often sealed units. If the sensor's port is clogged with carbon, cleaning it with a dedicated electronic parts cleaner may help temporarily, but replacement is usually the permanent solution. A faulty sensor is an electrical failure inside, which cleaning cannot fix.
Is there a recall on the MAP sensor for the 1993-2002 Mirage?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) related to the MAP sensor for this generation of Mitsubishi Mirage.
What's the difference between a MAP and a MAF sensor?
Your Mirage uses a MAP (Manifold Absolute Pressure) sensor. Some other cars use a MAF (Mass Airflow) sensor instead, or sometimes both. A MAP sensor measures air pressure in the intake manifold, while a MAF sensor measures the volume and density of the air entering the engine. They perform a similar function but measure different things to get there.
