Check engine light but no codes are comming up
So a couple days ago i had my CEL on and i had EVAP codes and wrong engine oil code so i took it in and got all that dealt with and a smoke test was done for the evap code and no leaks were found.
they reset my PCM after they were done and the next day my CEL came back on but no codes are coming up.
I do the "key dance" and the dash beeps 5 times and then says "done" but no codes show up.
if i leave it the CEL flashes 10 times.
Can anyone help?
Let me know
