Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, in order to try and help, Engine size? code#? FS Bronco or small Bronco?
Full size eith a 5.0 engine. I don't have the code number but I I remember it was the left front output valve.
well, hard to say, Diagnaostic has to be done, I have include a a couple links, The wiring diagram as well as the pinpoint chart, You have to use both links to see pin numbers and run tests,Yes,, could have been the ECU but the codes will not auto clear until 50 ignition cycles with no ABS cods setting so,, this can take some time for the code to clear. you can do the pin tests at the ECU plug, withouta breakout box
When you say ignition cycle, does that mean strating the vehicle 50 times?
well, sort of, it is more about drive cylces meaning starting engine from cold state, say in am, then come home from work, driving it, then repeat., You can not just cycle the key 50 times.,It has to go through*****cycles
