DTC Advanced Diagnostics: P0069: General Description
The barometric pressure (BARO) sensor is built into the powertrain control module (PCM) and monitors atmospheric pressure. The measured BARO sensor value is compared with the value of the manifold absolute pressure (MAP) sensor before the engine is started. If the difference between the measured BARO sensor value and the value of the MAP sensor before the engine start is excessive, the PCM detects a malfunction in the BARO sensor output and stores a DTC.
