Mazda Repair Questions? Ask Mechanics for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question
You should have a pulse signal on that wire, which leads me to believe it may have shorted the ecu on that circuit, but I need the last 8 of the vin to pull all the schematics to verify
Once I get the last 8 of the vin, I should be able to pull up the ecu connector pinout that will have the voltage readings they should have
I will have to opt out as my wiring diagrams dont even have wire colors and no connector pinouts. If another expert can help, they will post here to you.
