DTC P0107: Manifold Absolute Pressure / Barometric Pressure Circuit Low Input; DTC P0108: Manifold Absolute Pressure / Barometric Pressure Circuit High Input [10/2015 - ]: Description
The manifold absolute pressure sensor detects the intake manifold pressure as a change in voltage. The ECM assembly calculates the intake manifold pressure based on this voltage. The ECM assembly calculates the EGR valve assembly and purge VSV opening amount according to changes in the intake manifold pressure and also detects errors in the manifold absolute pressure sensor using these changes in pressure.
