P0068 DODGE Manifold Absolute Pressure/Mass Air Flow Sensor – Throttle Position Correlation

Possible causes
– Faulty Mass Air Flow (MAF) sensor
– 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
When is the obd code mean?
The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
– Lack/Loss of power
– Engine rough idle
P0068 DODGE OBD Code Description

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.
