Drive with caution — fix soon.
This code means your car's computer noticed the mass air flow sensor is reporting a value that doesn't match what the engine is actually doing. The MAF sensor measures how much air enters the engine so the right amount of fuel can be added. When its signal is off, the air-fuel mix gets thrown out of balance.
$80 – $350
Varies by vehicle and root cause.
For short trips, usually yes, but the engine may run poorly and waste fuel. It's best to get it diagnosed within a few days so a small issue doesn't grow into a bigger one.
Often between $80 and $350. Simply cleaning the MAF sensor or fixing a loose hose is cheap, while replacing the sensor itself costs more.
It's moderate. Your car won't break down immediately, but ignoring it can lead to poor performance, higher fuel use, and added wear on the engine over time.
Yes. A clogged filter or one that lets dirt onto the MAF sensor can throw off its readings. Cleaning the sensor and replacing a dirty filter often resolves the code.
