Drive with caution — fix soon.
This code means the engine computer detected a problem in the electrical circuit of the mass air flow (MAF) sensor, which measures how much air enters the engine. It's often caused by a dirty or failed MAF sensor, but can also come from wiring issues or vacuum leaks. It's a common code and is usually fixable by cleaning or replacing the sensor.
$100 – $400
Varies by vehicle and root cause.
For short trips, usually yes, but you shouldn't rely on it. The car may run rough, hesitate, or stall, and you'll likely burn extra fuel. Get it diagnosed soon to avoid being stranded.
Most repairs run between $100 and $400. If the sensor just needs cleaning the cost is low, but a full MAF sensor replacement with labor pushes toward the higher end.
It's moderate. It won't usually damage your engine right away, but it affects fuel mixing and emissions, so it can lead to stalling and poor performance if ignored.
Yes, indirectly. A clogged filter or unmetered air leak can throw off the MAF sensor readings. Often a simple cleaning of the sensor and a fresh air filter clears the code.
