Drive with caution — fix soon.
This code means the engine computer detected a problem in the manifold absolute pressure (MAP) sensor circuit, which measures engine load by reading intake manifold pressure. It's often caused by a failed MAP sensor, wiring problems, or a blocked vacuum hose. It's a common code and is usually fixable by repairing the wiring or replacing the sensor.
$100 – $350
Varies by vehicle and root cause.
For short trips, usually yes, but the car may run rough, hesitate, or stall. Since the computer can't read engine load properly, performance and fuel economy suffer. Get it diagnosed soon.
Most repairs run between $100 and $350. A MAP sensor itself is fairly inexpensive, and labor is usually modest since it's easy to access on most engines.
It's moderate. It won't usually destroy your engine, but incorrect pressure readings affect fuel mixing and timing, which can cause stalling and poor performance if left unfixed.
Yes. A cracked, blocked, or disconnected vacuum hose feeding the MAP sensor can throw off its readings and trigger this code. A mechanic will check the hose and connections before replacing the sensor.
