MAP/Barometric Pressure Circuit Range/Performance Problem
The engine computer is getting a MAP sensor signal that does not match the engine’s actual vacuum and load. This can be caused by a bad sensor, wiring problems, or an engine vacuum leak. It can lead to rough running, poor fuel economy, and stalling.
You may be able to drive short distances, but the engine may run poorly, stall, or lose power. If the check engine light is flashing, the engine is stalling, or performance is severely reduced, do not keep driving.
P0106 sets when the PCM sees a manifold absolute pressure sensor or barometric pressure reading that is outside the expected range for current engine conditions. The signal may be inaccurate, slow to respond, or inconsistent with throttle position, engine speed, and load. The fault can be caused by the MAP sensor itself, vacuum leaks, intake leaks, wiring faults, restricted ports, or sometimes a barometric pressure calculation issue in the PCM.
Yes. An incorrect MAP signal can make the engine run too rich or too lean, which can cause rough idle or stalling.
It may clear temporarily if the issue is intermittent, but the code usually returns until the fault is repaired.
No, but a vacuum leak is a common cause. The code means the MAP reading does not match expected engine conditions.
Often yes, if it is easy to access and you can safely disconnect the connector and hose. You should still inspect for vacuum leaks and wiring problems first.
