P0068 Volkswagen Code - Manifold Absolute Pressure/Mass Air Flow Sensor - Throttle Position Correlation
Quick Answer
The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. Common causes include Faulty Mass Air Flow (MAF) sensor, Large vacuum leak, Leaking air duct system. 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.
