Hello, recently my 2003 Elantra's check in engine came on. No performance issues or engine issues that I can tell. First time I checked the ECU it showed P0038 and the other time it showed P0032. On one drive the speedometer started twitching, so I suspect something electric. I did a quick check around the wiring on the O2 sensors but couldn't see anything obvious. Any ideas for next steps to diagnose?
