P0106 Manifold Absolute Pressure Sensor Range/Performance
The manifold absolute pressure (MAP) sensor signal is implausible relative to throttle position and engine speed. The ECU expects MAP to rise with throttle opening and fall under deceleration; deviation triggers the code.
Is it safe to drive with P0106?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyVacuum hose to MAP sensor cracked or detached
- PossibleMAP sensor drifting outside specification
- PossibleIntake manifold gasket leaking
