Drive with caution — fix soon.
This code means the manifold absolute pressure (MAP) sensor circuit is sending a signal that's too low, often indicating a wiring short to ground, a disconnected sensor, or a vacuum hose problem. The engine computer can't gauge load correctly, which affects fuel mixing. It's a common code and is usually fixable by repairing wiring, reconnecting the vacuum line, or replacing the sensor.
$100 – $350
Varies by vehicle and root cause.
For short trips, usually yes, but the engine may run rough or rich and could stall. Since the sensor reads too low, the computer mixes fuel incorrectly. Get it diagnosed soon.
Most repairs run $100 to $350. A wiring or connector fix is on the lower end, while a new MAP sensor with labor sits a bit higher.
It's moderate. It won't usually cause immediate engine damage, but the low reading throws off fuel mixing and can cause stalling and poor performance if left unfixed.
A low signal usually means the circuit is shorted to ground, the sensor is unplugged, or a wire is broken. A mechanic checks the connector and wiring first, since those are common and cheaper than the sensor itself.
