Service

What is the Manifold Absolute Pressure Sensor (MAP Sensor) all about?

In order to operate, your engine needs a combination of air, fuel and spark. Today’s engines are much more complex, and require sophisticated measuring of different elements to ensure proper fuel combustion. The manifold absolute pressure (MAP) sensor is responsible for some of these tasks.

Your MAP sensor measures the amount of air entering the manifold, the air temperature, and the number of revolutions in the engine. With this information, the car’s computer can adjust fuel and airflow to maximize performance while minimizing fuel consumption.

If your engine is not fuel injected, you probably do not have a MAP sensor. However, the vast majority of engines on the road today are fuel injected. For some automakers, the MAP sensor also serves a diagnostic function, allowing mechanics to analyze the performance of the EGR valve.

Keep in mind:

  • The MAP sensor is an electronic component, and can fail unexpectedly.
  • It is impossible to determine if the manifold absolute pressure sensor has failed with a visual inspection – it will require an experienced mechanic to diagnose the issue.
  • A failing MAP sensor will trigger the Check Engine light.

How it's done:

  • The vehicle hood is raised and supported
  • The defective manifold absolute pressure sensor is removed
  • The new manifold absolute pressure sensor is installed
  • The computer is tested and codes cleared with a scanner
  • The vehicle hood is closed and road tested for proper operation

Our recommendation:

While a failed MAP sensor won’t disable your car, it’s strongly recommended that you have it diagnosed and replaced as quickly as possible. Driving with a failing or failed MAP sensor can cause your engine to run “rich” or “lean” – that is, with either too much fuel, or too much air. Both of these conditions can damage the engine. However, there are many other conditions that can mimic a failed MAP sensor, including relatively minor vacuum leaks, so it’s important that one of our expert mechanics check the malfunction code and thoroughly inspect the engine.

What common symptoms indicate you may need to replace the Manifold Absolute Pressure Sensor (MAP Sensor)?

  • Erratic or rough idling
  • Delay in acceleration or deceleration
  • Check Engine light is on
  • Excess exhaust emissions resulting in failed emissions test

How important is this service?

Your engine’s MAP sensor is an important piece of technology, and should be replaced immediately to avoid potentially damaging your engine with lean or rich operating conditions and to ensure you’re able to pass your emissions test. If you notice any of the symptoms above, or your Check Engine light is on, have your vehicle diagnosed by one of our expert mechanics.

Subaru Legacy - Timing Belt - Austin, Texas
Tim got in touch with me right after I put in my order for service to get more information, as he lots of experience with Subaurus and suspected my original diagnosis might have been incorrect or insufficient. Turns out he was right. It was a completely different problem altogether, My car threw a rod and needs a new engine (I was originally told the timing belt had broken). He explained exactly what he checked out and how he found the hole in my engine block. He had good advice on the pros and cons of getting a used engine at this point in the life of my car, and he had some helpful hints for haggling with junk shops, too. He went the distance to make sure I wasn't charged for his visit, as my original diagnosis was useless. Tim is a no BS, highly skilled mechanic who knows his stuff.

Subaru Legacy - Spark Plugs - San Leandro, California
I got a text saying Tien was on his way, so the five minutes he was late due to traffic and a part pick up didn't bother me at all. He did exactly the service I requested, plus an overview of my newly purchased used vehicle, and didn't try to sell me a bunch of extra services. I was given a quote of $171 when I made the appointment, and I was charged exactly $171 when the service was completed. Pep Boys gave me an estimate for the same service of c "$325, minimum" just last week! Tien did find an additional issue I need to take a look at, and gave me a reasonable explanation with pictures showing the area that needed attention. i'll be booking the service for that in a couple weeks. The ease of making an appointment and paying online, the convenience of them coming to me, the integrity of their quote being the actual price, and the thorough service provided will keep me coming back (and recommending to my friends) for all my maintenance and service needs!
