P0068 KIA Possible Causes

  Faulty Mass Air Flow (MAF) sensor,Large vacuum leak,Leaking air duct system,Mass Air Flow (MAF) poor electrical connection,Manifold Absolute Pressure (MAP) poor electrical connection,Faulty Manifold Absolute Pressure (MAP) sensor,TP sensor not seated properly,Faulty Throttle Position (TP) sensor  

P0068 KIA 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.
