P0068 Acura Manifold Absolute Pressure/Mass Air Flow Sensor – Throttle Position Correlation
– Large vacuum leak
– Leaking air duct system
– Mass Air Flow (MAF) poor electrcial connection
– Manifold Absolute Pressure (MAP) poor electrcial connection
– Faulty Manifold Absolute Pressure (MAP) sensor
– TP sensor not seated properly
– Faulty Throttle Position (TP) sensor
– Lack/Loss of power
– Engine rough idle
The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
