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 hybrid vehicle control ECU controls the purge VSV and detects errors in the pressure sensor using the changes in pressure.
