DTC P0068: Throttle Position (TP) Sensor Inconsistent With Mass Airflow (MAF) Sensor: Condition
WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
DTC is set when Powertrain Control Module (PCM) detects input voltages from TP sensor and Mass Airflow (MAF) sensor are not consistent with calibrated load values. PCM compares actual input voltage from MAF sensor with expected input voltage from MAF sensor which PCM calculates using input voltage from TP sensor. This is a continuous monitor. MIL is illuminated when PCM detects malfunction during 2 consecutive drive cycles. Possible causes are:
- MAF sensor malfunction.
- TP sensor malfunction.
