Eng check and dash lights galore

[CHawks_12]

And here again the lights return. I'm running out of ideas on what it is. THe only part I have yet to replace is the CAT. I am trying to avoid replacing it due to $$$$$. I have done some research and found that it may throw a code after replacement of the o2 Sensors, just cann't remember what the code was. I hope that is all it is and resetting it will fix it.

Any SME's out there please weigh in. THanks :help: :thanks: :yield:

Yes, it will help us if you post codes. I have full access to Toyota codes and diagnostics, as well as wiring diagrams.:driving:

I will post the codes if the issue returns. The lights came on Monday afternoon. I reseated the gas cap and this morning the lights didn't come on. Could temp changes cause the lights to come on? Thanks
