Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P0068 Pontiac code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
If the PCM detects that the difference between the actual air flow (MAF) and the speed density calculated air flow is greater than expected, DTC P0068 sets.
The Powertrain Control Module (PCM) uses the Throttle Position (TP), Barometric Pressure (BARO), Intake Air Temperature (IAT), and engine RPM in order to calculate the predicted mass airflow rate. The PCM compares the predicted Mass Air Flow (MAF) value to the actual mass airflow value and the speed density calculation in order to verify the proper throttle operation.
