I have a 94 Camaro Z28 Convertible, automatic w/116k on it. Owned it for almost 10 years, and I always try to keep up the routine maintenance. I'm capable of replacing just about any part, but I'm a terrible troubleshooter.

Problem #1: The ABS INOP light is consistently on. Had a test done and said the front drivers sensor was bad. I replaced the sensor, hub 'n all and the light is still on.

Problem #2: The Low Coolant Sensor is consistently on. I cleaned the sensor, flushed and refilled the system and still on. I then replaced the sensor and again the light is still on. The reservoir is full and engine temp is fine, but light is still on.

I've read several threads on both problems, but found nothing past this point. I've been thinking the wiring harness is bad somewhere. But before I spend the $$$ and time on replacing that bad boy, I was hoping for some suggestions. HELP PLEASE???

Thank you

 

i am gona say the wiring harness to the wheel sensor is failing. at least that is a weak point in the wiring. coolant level sensor system has a relay, at least the 93 does. heres what i could find.
