The P0106 trouble code generally means an issue with the MAP circuit having incorrect output range issues or a
problem with engine performance. The diagnostic code is set when either the Power Train Control Module (PCM) detects
an abnormal signal voltage from the Manifold Absolute Pressure (MAP) sensor relating to the current throttle position
or engine load or a signal voltage that does not show a good relationship with the MAP sensor. The MAP sensor is
integral to the fuel injection system, providing signals to the Engine Control Unit (ECU) to allow smooth operation,
good fuel economy, and proper performance and power. The P0106 diagnostic code is generally activated more commonly on
vehicles with higher mileage of over 100,000 miles.
