DTC P0106: Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance Problem [08/2014 - ]: Description

The manifold absolute pressure sensor detects the intake manifold pressure as a voltage using a built-in sensor. The ECM calculates intake manifold pressure based on this voltage and also calculates the EGR valve and purge VSV opening amount according to changes in the intake manifold pressure.
