Code P00C7 2015 GMC Sierra Description

The Intake Air Pressure Measurement System consists of (2) sensors, the Barometric Pressure (BARO) Sensor, and the Manifold Absolute Pressure (MAP) Sensor. The Diagnostic Trouble Code (DTC) will be set when the ECM detects an inconsistency between pressure sensors in the induction system in which a particular sensor cannot be identified as the failed sensor. The difference between them is greater than 10 kPa (1.5 PSI).
