How do I clean the MAP sensor on my Honda?
I’ve noticed that my Honda’s gas mileage has gone down significantly over the past month or so. I’ve tried everything to fix it. My mechanic buddy told me that I may just need to clean the MAP sensor, but I’ve never done it before. How do I clean a MAP sensor on a Honda?

The MAP sensor, or manifold pressure sensor, calculates the air-to-fuel ratio of your car. When it’s dirty, the engine control unit (ECU) can’t create the proper mixture, which leads to poor fuel economy. If your friend is right, this may be the problem.
To clean a MAP sensor, here’s what you’ll need to do:
- Find the MAP housing assembly
- Unplug it
- Spray it with parts cleaner
- Reassemble it
The MAP sensor is usually at the front of the engine, although you may want to consult your owner’s manual to be certain.
Once you locate the MAP sensor, remove the two or three screws holding it in place. Unplug the wiring harness, use parts cleaner, and slap the MAP sensor back into place. That’s all there is to it!
In most cases, you should simply make cleaning your MAP sensor a part of your
basic car maintenance schedule
to avoid future issues.While insurance won’t cover a dirty MAP sensor, it will protect you in the event of an accident. But don’t pay more than necessary. Use the
