I had to undo the steering shaft to installed long tube ARH. I got a service stabilitrak and o2 sensor codes CEL.After searching this sight I
determined I had rotated the steering shaft trying to get it installed.
I took the shaft apart twice and rotated it before the stabilitak light
would stay off.I thought I had the problem solved but now on start up
my dash lights say stabiltrak off. The stabilitrak button does not do
anything and seems a to have no power to it.I tried to find a fuse or relay for this but no luck.I took out all of spark plugs and checked for damaged and they look ok.I also checked all header bolts and exhaust
and seem to be no leaks.I have been on this forum looking for a solution
and I now thinking that I might have did something to the spring or the
wheel angle sensor in the steering wheel. Could the sensor in the wheel
become unplugged by rotating the wheel to much.Can I take off the wheel and maybe do something with the spring or sensor.
I cannot find any thing on this sight that tells me why I would have no stabilitrak and no service stabilitrak warning light. I purchased the JRE SCT programmer and when installed I hope it will eliminate the codes.
I also have a CAI,Air Scoop, RX Catch Can,Magnaflow cat back street series exhaust on my L99.I do have a trinity programmer that shows the
codes P0056, P0160,P0161.The reason I purshased the SCT is to get the
transmission tune.It is great that you can go to a sight like this and find solutions to a problem.
