Mass Air Flow (MAF) Sensor Chevrolet Malibu 2.5L 2013-2015 Location and Replacement

In this video, I show you the exact location and the complete step-by-step process to replace the Mass Air Flow (MAF) sensor on a 2013-2015 Chevrolet Malibu with the 2.5L engine.

Knowing exactly where this sensor sits on the air intake duct and how to safely swap it out will save you time and keep you from damaging your vehicle’s sensitive intake system during this straightforward DIY fix.

Common Symptoms of a Bad Mass Air Flow (MAF) Sensor:

• The check engine light comes on, frequently flagging EVAP or fuel trim codes like P0101, P0171, or P0174
• The engine idles roughly, stumbles, or vibrates excessively when sitting at a stoplight
• A noticeable loss of engine power, sluggish acceleration, or hesitation when stepping on the gas pedal
• Severe engine stalling or difficulty starting the vehicle shortly after cranking
• Poor fuel economy as the engine control module miscalculates the air-fuel mixture

Safety First

Always prioritize safety before starting your repair. Make sure the vehicle is safely parked on a flat, level surface, the emergency brake is securely engaged, and the engine is completely turned off with the keys removed from the ignition. Allow the engine compartment plenty of time to cool down fully to avoid painful burns from hot engine components. Consider disconnecting the negative battery terminal to prevent any accidental electrical shorts while handling sensor connectors. Protect your eyes and hands by wearing safety glasses and durable work gloves, and maintain your full focus throughout the task.
