should the sensor hold a vacuum? i have ruled out everything using this and made sure i used the proper voltage specs for the pfe and not the dpfe. the only thing i am unsure on is if that sensor should hold a vacuum or not.
thats the process i used and everything checks out . however the system in the tests uses the newer differential feedback sensor and my vehicle uses the older feedback sensor with a single port..
My sensor will not hold a vacuum but i wanted to make sure it should before i shelled out $50 for a part
