Manifold Absolute Pressure Sensor (MAP Sensor) Replacement 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.

Mercury Grand Marquis V8-4.6L - Brake Pads Replacement (Rear) - North Las Vegas, Nevada
Marvin is totally cool, professional and knowledgeable. He explained everything and patiently answered our questions plus he double checked services that another auto shop had included in their estimate., My first attempt at getting the car serviced was a total waste of time,. It took them over 5 hours to look at the car and when they finally contacted me it was to give me an estimate that was 3x more than the original quote. The first shop I took the car too didn't seem to care about my time and I felt that they were trying to rip me off by charging for services not needed which included parts and labor expenses that they probably wouldn't have done but charged for anyway. Yourmechanic.com was so much more convenient. I didn't have to worry about finding rides before and after dropping the car of at the shop because Marvin came to us after I saved my online quote and made an appointment for the same day. I wasted over 6 hours and received a quote for $826.67 (original quote was $252-275) and nothing was done because I refused to have the work done after they told me that the brake pads, calipers, rotors and brake hoses needed replacing even though I told them when I dropped the car off that we only needed front and rare brake pad replacement. Marvin came out to us on the same day and was completely done within 3 hours for $336.42(original quote was $259.47) There was an additional charge of $76.95 because one of the rotors also needed replacing. Before leaving, Marvin informed us of what services were going to be needed soon which included adding motor oil. and windshield wiper fluid which are easy enough for me to do so he told me what kind of motor oil to buy and didn't mind at all that I was trying to save money by doing what I could myself. We will be scheduling Marvin to come out again so that the brake lines can be flushed. He already submitted the quote online. All I'll need to do is accept the quote and schedule an appointment. II really like Marvin. I have absolutely no complaints with regard to anything he did, he saved us approximately $500, he was quick, efficient and was very easy to communicate with. The best part was that he didn't talk down to me at all or try to rip me off like the other auto shop did (MAC) I highly recommend Marvin, he's a good, honest mechanic.
