On the same subject. My speedo and tach are working fine but the car is throwing the VSS code every time I drive it. It also smells like it's running a bit rich. Does the VSS work along side the other sensors that adjust fuel/air?
Well I found a replacement (used) and I'm still throwing the code 24. Is there a test procedure that anyone knows about or should I just assume that my ECM/ECU is the problem since it's a 91 T5 Speed Density car???
You'll need to hook up a scan tool and see if the ECM is seeing the correct speed as well.
Speedo works. It even seems accurate when compared to my GPS. Like I mentioned earlier. I've tried two VSS sensors and they both produce the same result (code 24). What scan tool would you recommend?
I'd also add that I had my prom flashed to tune out the EGR and AIR components. I mailed it out to harris performance and he did the tune based on my car. I just had the engine rebuilt prior to this, so I really can't pinpoint if it happened after the new prom tune. I just knew that when I had it all apart that I didnt want to bother with all of the emissions crap when putting it all back together. It it possible that could have something to do with my code 24?
Another thought. Does anybody know which/what color wires at the ecm are for the VSS. I was thinking I could bypass the harness and splice/wire the VSS directly into the ECM to rule out a short. Just do that and take a drive with the wire(s) run from under the car through the drivers door and into the ECM. Thoughts?
