If you do not have a professional scan tool you cannot do it. See pictures.

Hello,

It could be a bad connection or a defective sensor. Is it a factory sensor? If not the resistance can be off which will cause that problem.

Please let us know what happens.

Cheers, Ken

If you do not have the professional scanner you cannot set cam/crank sensor sync an auto parts scanner will not do this what type of scanner are you using.
