DTC P0068: Notes

DTC P0068 (MZI-3.5) DETECTION CONDITION AND POSSIBLE CAUSES

DTC P0068 MAP/MAF-throttle position correlation
DETECTION CONDITION 
  • The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during a KOER self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, test fails and a DTC is stored in continuous memory.
POSSIBLE CAUSE 
  • Air leak between MAF sensor and throttle body
  • TP sensor or MAF sensor malfunction
  • TP sensor not seated correctly
