Fault Codes:  

P0106 – MAP Sensor Range/Performance Problem, P0107 – MAP Sensor Circuit Low Input, and P0108 – MAP Sensor Circuit High Input, all affecting engine performance and efficiency.

The MAP sensor can fail due to carbon buildup, vacuum leaks, wiring corrosion, or sensor element degradation from constant exposure to heat and intake vibrations. Over time, this leads to inaccurate pressure readings, which affect the air-fuel mixture and overall engine performance.

Symptoms:

• Rough idling and hesitation during acceleration
• Poor fuel economy due to incorrect fuel delivery
• Engine misfires or stalling under load
• Sluggish throttle response and reduced power
• Check Engine Light illuminated with stored MAP sensor codes
