So I posted awhile back about my ABS light being on but not being able to pull codes. The other day I replaced my oxygen sensors with Motorcraft's OEM sensors due to a CEL (check engine light) that came on every so often. They fixed the CEL and actually got rid of the misfire feel I was having cruising at 2k on the freeway. Oddly when I replaced the sensors I noticed a few days later that my ABS light was gone (I also had an exhaust leak at the header/midpipe flange). After about 20 miles I stopped at a gas station (not for gas) and when I turned my car back on it was back. Today when I started it up to go rent my mechanic's lift to fix the exhaust leak the light was off again. After I fixed the exhaust leak the light came back on a few miles down the road. When I scanned the ABS there were no codes in the memory. Anyone experience this before? This was the first time in over 3 months the light went away. Previous owner said the light came on when they were getting it smogged. That along with the exhaust leak makes me wonder if it's somehow connected?
