DTC P0106: Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance Problem: Description

The manifold absolute pressure sensor detects pressure inside the intake manifold as an absolute pressure with a built-in sensor and outputs a voltage. Based on the voltage from the manifold absolute pressure sensor, the ECM controls the air fuel ratio and detects errors in the pressure sensor using the changes in pressure.
