Drive with caution — fix soon.
This code means the manifold absolute pressure (MAP) sensor circuit is sending a signal that's too high, often from a wiring short to power, a disconnected vacuum hose, or a failed sensor. The computer then over-fuels the engine, hurting economy and emissions. It's a common code and is usually fixable by repairing wiring, fixing the vacuum connection, or replacing the sensor.
$100 – $350
Varies by vehicle and root cause.
For short trips, usually yes, but the engine may run rich, idle rough, and waste fuel. Since the sensor reads too high, the computer over-fuels the engine. Have it diagnosed soon.
Most repairs run $100 to $350. A wiring or vacuum hose fix is cheaper, while a new MAP sensor with labor sits toward the higher end.
It's moderate. It won't usually cause immediate engine damage, but running rich for a long time wastes fuel and can foul spark plugs or harm the catalytic converter, so don't leave it too long.
A high signal usually comes from the circuit shorting to power, a disconnected vacuum hose, or a failed sensor. A mechanic checks the vacuum connection and wiring before deciding whether the sensor needs replacing.
