DTC P0068: Manifold Absolute Pressure (Map)/Mass Air Flow (MAF): Throttle Position Correlation

WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2013 Lincoln Navigator, 2013 Lincoln MKZ, 2013 Lincoln MKX, 2013 Lincoln MKT, and 2013 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.

DTC P0068: MANIFOLD ABSOLUTE PRESSURE (MAP)/MASS AIR FLOW (MAF): THROTTLE POSITION CORRELATION

Description:	The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass airflow readings. This continuous memory DTC sets when during a key ON, engine running (KOER) self-test, the comparison of the throttle position (TP) sensor and MAF sensor 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 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. Diagnose any MAF or TP DTCs first. For Fiesta, if the throttle plate is closed, the ETB_CALC_CORR PID is greater than 30% or the LOAD PID is greater than 35%, or with the TP_REL PID at 28% with the LOAD PID less than 30% indicates a concern is present. For all others, if the throttle plate is closed and the LOAD PID is greater than 55%, or with the throttle plate at wide open throttle (WOT) with the LOAD PID less than 30% indicates a concern is present.
