At this time, the conditions required to set the DTC are not present.
Note: Use the Freeze Frame Data to help duplicate the conditions that set
the DTC. Pay particular attention to the DTC set conditions, such as, VSS,
MAP, ECT, and Load.
Note: Visually inspect the related wiring harness. Look for any chafed,
pierced, pinched, or partially broken wires.
Note: Visually inspect the related wiring harness connectors. Look for
broken, bent, pushed out, or corroded terminals.
Note: Refer to any technical service bulletins that may apply.
