Water intrusion in the instrument panel to body harness connector may set off this trouble code. The accelerator pedal position (APP) signal runs through this harness. To fix the problem, locate the IP-t0-body harness near the left hand kick panel. If you find water in the connector, you’ve located the problem with the APP signal. Repair any corrosion and then fix the leak. Check the A-pillar seals, windshield cowling, and sunroof drains
