I Have another Forum I have been working on this Buick allot for some time now.
95 Park Avenue Motor Swap
Right now I'm fine with how everything is running and showing up besides my speedometer and odometer not working. I have an engine light on and OBD1.5. So I am using TunerPro to try and pull codes. All sensor outputs are jumping to random numbers it seems, alternator shows is faulty, valve showing in open close loop, running lean and rich, and is throwing every single code on and off. But my car runs drives shifts start and everything fine. Things not working are the Traction control, cruise, speedometer, & odometer. I am being told the ECU or PCM (aka Computer) or something like that.
I replace the vehicle speed sensor connector and the sensor. This made no difference. I know that there is a sensor inside of the transmission. But since I just put this motor in and got it running the way it is I really do not want to have to drop the motor and trans out to check this one sensor. My next question is will a ABS wheel speed sensor cause my speedometer to not work. Also could it be my PCM even if all of my other tacks and sensors work and show appropriate readings?
