checked voltage while engine running at the maff sensor,, using the center pin as ground,, two pins to the right are 5 volts each, to the left 2pins voltage varies,, this would be the sensing voltage. used by ecm to determine fuel ratio...it seems this circuit is working.. the code seems to set in open loop.. when engine cold no code until warm up
