I'm no tech when it comes to these newer vehicles, so my understanding of all the sensors is rather sketchy.
I just ran codes on my 5.8 E250 ('93, OBD I), and got code 123, TPS above max voltage, in demand, stored and KOER. If the TPS is above max voltage, should I just replace it? Or should I test it first, then look for some other issues if it tests good?
I also got a 332 code, which was stored, saying EGR valve opening not detected. It wasn't on demand, so could that code have been registered when I pulled the large vacuum line at the brake booster to do a Seafoam treatment? Or do I need to do a full EGR diagnostic?
I also pulled a stored 628, excessive converter clutch slippage. I recently did a filter and pan gasket, and did drive some with low trans fluid. I just erased codes. Should I watch to see if the code returns? Or do I need to figure on converter problems?
Thanks for any help!
