Causes and Fixes P0106 Code: Manifold Absolute Barometric Pressure Sensor Range Performance

How to fix a P0106 engine code: Manifold Absolute Barometric Pressure Sensor Range Performance

The MAP (Manifold Absolute Pressure) sensor measures engine manifold pressure.
The BARO (Barometric Pressure) sensor measures atmospheric pressure.
The MAP sensor and BARO sensors are usually combined into a single sensor.
Some vehicles do not use a MAP sensor but use a Mass Airflow (MAF) sensor, while some vehicles have a MAF and MAP sensor.

Possible Causes of a P0106 Code:
Bad MAP/BARO sensor
Wiring (Open Short)
Vacuum Leak
Clogged Intake, such as dirty air filter
Clogged Exhaust, such as bad catalytic converter
