Drive with caution — fix soon.
This code means the engine computer detected an intermittent fault in the manifold absolute pressure (MAP) sensor circuit, where the signal drops out or jumps now and then rather than constantly. It's usually caused by loose or corroded wiring and connectors, or a sensor starting to fail. Intermittent codes take patience to pin down, but they're often fixable by repairing connections or replacing the sensor.
$100 – $350
Varies by vehicle and root cause.
Usually yes for short trips, but the intermittent signal means performance can drop without warning. You may feel occasional hesitation or stumbling. Get it diagnosed before it becomes constant.
Repairs typically run $100 to $350. A wiring or connector repair is cheaper, while replacing the MAP sensor with labor costs a bit more.
It's moderate. It won't usually cause immediate engine damage, but the on-and-off signal can lead to stalling and poor performance over time, so it's worth addressing.
Intermittent faults usually come from loose or corroded connections that only lose contact under vibration or heat. A mechanic will often wiggle-test the connector and wiring to find the weak spot before replacing parts.
