So my 3 amigos recently came on and I scanned them using my Autocom. I had 066 (front left sensor electrical failure) and 115 (unknown). I fixed the 066 and cleared the codes. Everything was fine for a few weeks and sure enough the lights came back on. I pulled the codes again and this time it was only code 115 (unknown). I have no idea what 115 is. I know 114 is the shuttle valve switch...any ideas?
