What To Do When Your MAF Sensor Goes Bad

Restore your engine’s full performance with a replacement mass air flow sensor. Your vehicle’s MAF sensor is essential for determining the amount of air in the fuel injection system.

Consequences of Not Replacing a Bad MAF Sensor

This tiny sensor may not seem like an essential repair. Unlike transmission issues or worn-out brake pads, an MAF sensor may not create an immediately dangerous driving situation. There are, however, still consequences of not replacing a bad sensor.

First, a vehicle without an operational sensor may hesitate or suddenly jerk forward. Unusual acceleration issues are caused by an improper balance of air and fuel. In extreme conditions, this can even cause your engine to stall.

A rich air/fuel ratio is another consequence of not replacing your sensor. You may experience rough idling, decreased fuel efficiency, black smoke from the exhaust, and an illuminated check engine light. These issues come from an inaccurate or missing signal from the MAF sensor. The powertrain control module may then send an incorrect signal, causing excessive fuel to be injected.

Finally, a lean air/fuel ratio can also be caused by MAF sensor issues. When too little fuel is injected, it can make it difficult to start your engine, cause surging, or cause hesitations.

How To Replace Your Mass Air Flow Sensor

These symptoms can come from a dirty or damaged MAF sensor. If you’ve determined that your sensor needs to be replaced, follow these steps. The exact steps can vary depending on the location and type of sensor in your vehicle, so be sure to discuss your project with a local auto parts store technician for personalized instructions.

First, gather the materials you need for the project. This will typically include gloves, a wrench, and a screwdriver. Park your vehicle in a flat, well-lit area before starting your repair project.

Remove the electrical connector from your MAF sensor. This may require a firm grip. Disconnect the sensor using a screwdriver. There are typically screws or clamps on each side of the MAF sensor. Use care to remove it, or you may damage the airbox or intake pipe.

Once the sensor is completely removed, determine whether you need to replace or clean it. Replacing it is as simple as inserting another sensor, putting the screws or clamps back in, and connecting the electrical connector.

Never touch the sensors on your MAF sensor. This may damage them or cause improper readings.
