What is a MAP sensor?
Since engines today operate with more complex processes than ever, the MAP sensor is an electronic feature that manages the amount and temperature of the air entering the intake manifold, relaying that information to the car’s computer. It then makes adjustments to optimize the engine’s performance while preventing it from overworking itself.
What are the symptoms of a bad MAP sensor?
There are the common symptoms to look for when evaluating the health of your MAP sensor:
The car makes rough or erratic motions when it’s idle (not moving)
The engine stalls when the car accelerates or decelerates
The check engine light turns on
Extra exhaust exits the engine, potentially resulting in a failed emissions test
If you’re noticing these signs, take your car to a mechanic for immediate inspection. Engine issues are serious, so it’s best to address problems as soon as possible.
How often do you need to replace a MAP sensor?
MAP sensors are meant to last the car’s lifetime. That being said, they usually start to show signs of wear after the 150k mile mark.
Is replacing a MAP sensor yourself easy?
If you want to replace a MAP sensor yourself, you should be confident in your auto repair and DIY skills. While it’s not the most challenging procedure, for the average car owner it’s best to let a certified mechanic diagnose and fix the problem.
