Q: How to clean map sensor? Where is it located?

asked by on

Low power. High fiel consumption.

My car has 70 miles.
My car has an automatic transmission.

The MAP sensor is usually located under the intake manifiold on most vehicles. This sensor needs to be very near to the combustion chamber to determine if a knock has occured. The intake manifold will almost always requre removal to access the MAP sensor. If the intake is to be removed to access the MAP sensor, it would be more beneficial to just replace the MAP sensor as opposed to just cleaning it. If you would like to have your MAP sensor replaced consider YourMechanic, as a certified technician can come to your home or office to replace the MAP sensor for you.
