Thanks for being so patient with this problem. It will be a few days before
I can get back under it to answer your questions definitely. It’s raining
now and I hate to get my wherlchair out on the rain plus I have to have my
neighbor help me with the jack stands. But if my memory serves me the
three(3) wires were black, white and green. I spliced the NTK(or if you get
it from their other division it’s calked NGK) into the OEN wiring harness
the same way I did when I replaced the original Bosch sensor about 15 years
ago with the Bosch sensor that is used in the Ford Mustang. This is the
replacement sensor that cross reference s to the Bosch number. . I always
had good results from the Ford sensor. It’s the one that everyone talked
about using to replace the expensive OEM Bosch. All wires are soldered, no
crimps. I determined the heater wasn’t working because after several
minutes of the engine running the sensor never fluctuated, it kept a
reading of around .5 volts. If I drive the car and get the sensor hot it
works just fine. The problem is that no matter what I do there is NO
voltage coming from the two wires that go to the heater from the wiring
harness . I’ll get under it this weekend and verify everything. Thanks
again Art.
