Is it code 9 or 90 for CEL check
Ok, I was checking a friends car. When I jumped the ecu to do a cel check I get 9 long flashes then it starts over again. I don't know for sure if that represents a code 9 for CYP or a 90 for EVAP Leak
How can I tell according to the flashes what is a 9 and what is a 90?
