P0068 - MAP/MAF - THROTTLE POSITION CORRELATION

Description:	The PCM monitors a vehicle operation rationality check by comparing the throttle position (TP) sensor to the mass airflow (MAF) sensor readings (if equipped) or to the manifold absolute pressure (MAP) sensor readings (if equipped). This continuous memory DTC sets when during a key ON, engine running (KOER) self-test, the comparison of the readings are not consistent with the calibrated load values.
Possible Causes:	Air leak at any connection or line of the intake air system components before or after the electronic throttle body (ETB) Leak in the positive crankcase ventilation (PCV) system TP sensor not seated correctly Damaged MAF sensor (if equipped) Damaged MAP sensor (if equipped) Damaged TP sensor
Diagnostic Aids:	An intake air system leak at a hose, line or connection of any intake air system or PCV system component may cause this DTC to set. Check for other DTCs. Diagnose all other DTCs first.
