I am trying to diagnose my CEL(s). It is a bunch of codes thrown at once when driving at freeway speeds for ~5 miles. CEL is never thrown when I am driving around town for reference.
Codes: 43, 1, 7, 20. These are a lot of codes that I never had before. We can see it's a Fuel System code, O2 Sensor, TPS, and Electrical load detector. These don't seem connected to my understanding of the fuel system. I tried replacing the Main Relay but I still throw the CEL with the same codes. I don't think it's the O2 sensor because it is relatively new from when I threw a code 41 about a year ago.
Some background info is that this started happening after I had my kill switch tied to my fuel pump disconnect (the wire was not soldiered properly) and it kept clicking the relay on and off. Maybe it damaged something else down the line? I am not really sure where to go with this, or where to start.
Let me know if you have any suggestions to tackle this issue. Ill continue to research in the meantime.
