Circuit/System Verification
- Verify the integrity of the air induction system by inspecting for the following conditions:
- Damaged components
- Loose or improper installation
- An air flow restriction
- Any vacuum leak
- Water intrusion
- A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor parameter on the scan tool to increase rapidly. This increase should be from 2-6 g/s at idle to 100 g/s or more at the time of the 1-2 shift.
- Verify that any electrical aftermarket devices are properly connected and grounded. Refer to Checking Aftermarket Accessories .
