Services Performed
- Scanned for codes and found codes P0430 catalyst efficiency bank 2. P2138 accelerator pedal position sensors 1-2 Not plausible. Found a technical service bulletin for the p2138 code stating (condition may be caused by water intrusion into the instrument panel to body harness connector, which carries the sensor circuit signals to the ecm/pcm. The water intrusion results in voltage differences that exceeds a predetermined value can cause P2138. The correction is verify any aftermarket components are not connected to the 5v references. Then locate the instrument panel to body connector and inspect for corrosion, water or debris. If present clean then retest). For the p0430 code need more time to review data and test some parts. Both bank 1 and bank 2 catalyst are passing but barely. Catalyst are bolted to the head. Rec replacing both cat assemblies w/ gaskets and inspecting and cleaning the instrument to body connector, per TSB instruction. Inspected the instrument panel to body harness connector and did find evidence of water, blew out the plug with compressed air and plugged back in.
- Tested fuses and both high and low beam fuses are good. Removed both headlight assemblies and tested found the driver side(left side) has a shorted ballast. The ballast is part of the head light assembly. Found water in both headlight assemblies which cause the left one to fail, so the right headlight assembly will fail in the near future because it is cracked as well. Recommend replacing both headlight assemblies.
