P0068 2012 Ford Fusion 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 sensed throttle position to mass air flow 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.

Code P0068 2012 Ford Fusion Description

The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during a key on engine running(KOER) self-test, the comparison of the throttle position (TP) sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a DTC is stored in continuous memory.
