P00C7 Code - Intake Air Pressure Measurement System Multiple Sensors Not Plausible
Quick Answer
The Intake Air Pressure Measurement System consists of (2) sensors, the Barometric Pressure (BARO) Sensor, and the Manifold Absolute Pressure (MAP) Sensor. Common causes include Faulty Barometric Pressure (BARO) Sensor, Barometric Pressure Sensor harness is open or shorted, Barometric Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
