yes, your pinout diagram showing where the pins are and the test 8.0-8.2 with wire color pretty much confirmed im on the right pin. my voltmeter was set at 12v I got 0.3v reading and my ohm meter set at 2k. for the ohm I had a 3.0 reading that pretty much totals my ohm to 6000ohm.
I was thinking it could be my recently replaced coolant sensor as defective but, since I am just getting a 0.3 volt reading at cold i don't see the need to go further. granting my engine is at 80-100c i should at least get 1v-0.9v. but i get 0.3v-0.4v
Should i still test ohm reading with hot engine?
