OK, I'm a newbie here so cut me a little slack if I don't make sense.
Here's my problem: On my daughter's '97 3.8 GT, the speedometer, ODO and cruise quit while she was driving. There are no engine codes set.
I've checked the vss. The resistance is good and no shorts. When I turn the wheels, I get pulses at the PCM. The check engine light is off.
I've swapped the instrument cluster out. I've checked for continuity from the instrument cluster connections back to the PCM. Everything appears to be good.
With the car lifted, I pulled the cruise connector and checked for a signal (vss out from pcm). According to what I've read, there should be 4000 pulses per mile. All I get is a constant 12 Volts whether at idle or with the car in gear.
Am I missing something? Any suggestions on what to check next???
