Every time I start the car and drive the abs inop light comes on at exactly 25 mph and stays on, before that abs works fine. I've replaced hubs thinking it was the wheel speed sensors but it's not. It also seems to have traction control but is a 94, which from what I've heard is impossible. Any ideas?

 

I had an ABS inop light and it was the Throttle position sensor. Once I changed the TPS it cleared up. I also had shifting problems at the time. Mine is an auto trans car.

 

I've been datalogging And the tps seems alright and its shifting smooth. I guess anything can cause the Damn light to come on.

 

Mine was the abs block module....it was a easy fix but idk how easy and affordable it is to buy...

 

Have you scanned it with an abs scanner?

 

No, I've just been datalogging it, is there a cheap program that'll scan the abs? I know theres no one around here that can scan obd1 with the obd2 connector
