Powertrain Codes

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

Symptoms

- Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of power - Engine rough idle

Possible Causes

- Large vacuum leak - Leaking air duct system - Mass Air Flow (MAF) poor electrcial connection - Manifold Absolute Pressure (MAP) poor electrcial connection - Faulty Mass Air Flow (MAF) sensor - Faulty Manifold Absolute Pressure (MAP) sensor - TP sensor not seated properly. - Faulty Throttle Position (TP) sensor. - Dirty throttle body

When Detected

The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings

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.
