What car? Are you asking about a MAP sensor, or a MAF sensor?

If it's a Honda, it's a MAP, if it's any of the others, it's usually a MAF sensor.

These sensors tell the car's computer how much air is coming in. The computer, or ECU, then decides how much fuel to add to match the amount of air there is.

A MAP sensor measures air pressure.

A MAF sensor measures air flow using an electrified wire. This wire is thin and fragile and is vulnerable to contamination by oil and dirt if your air filter is dirty or not doing its job. If you're having problems with an air sensor, 10 to 1 bet it's a MAF sensor. A MAF sensor can easily be cleaned using Electrical Contact Cleaner (Silicone-based, so it won't leave residue).
