P0405 Engine

When you check engine light came on code P0405 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However your vehicle's manufacturer may have a different definition for the P0405 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

Theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $200-$300 depending on the car, but that's usually the cost of parts because the labor is relatively simple.
