- Make sure this fits by entering your model number.
- MAF (mass air flow) sensors are located between the air filter and the throttle body and are responsible for measuring the amount of air entering the engine. It is part of your vehicleâs electronic fuel injection system. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. Youâll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. You may also notice youâre filling up at the gas station more than usual.
- A contaminated or failed MAF sensor cannot measure the amount of air flow correctly.This causes engine computer to miscalculate the amount of injected fuel. As a result, a bad sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. In addition, a faulty sensor might cause Check Engine or Service Engine Soon light to come on. Make sure to fix the problem right away so you can be safe, avoid costly repairs and avoid being stranded on road.
