Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello and welcome to just answer, my name is ***** ***** master tech here to help. I cannot see your vehicle so I rely on your input to my questions so I can better help you. I read your question and what you tried so far. Looks like you have tried just about every thing pertaining to that code but one basic.
Possible causes- Faulty Camshaft Position Sensor- Camshaft Position Sensor harness is open or shorted- Camshaft Position Sensor circuit poor electrical connection- Faulty starter motor- Starting system circuit- Dead (Weak) battery
Have you done a battery load test and starter draw test? this is important as these newer vehicles require a higher reserve voltage to run things or the ECU will randomly spit out anything. So that said , do you know what the reserve voltage you have while cranking?
Thanx for that info, and yes your correct as to the reserve voltage needed.Reading all your notes ans checks you did I would try a new Ecu as all the checks are good that you did.
