I have a CTS with 150k miles on it. I got a code that the left rear sensor was no longer reading. Stabilitrak, AWD, and ABS are disabled. I replaced the sensor. Same problem. So, its not the $15 sensor. I am guessing that means I have a dead computer somewhere? Any idea how to troubleshoot this thing?

No ideas? Could really use some thoughts on this one.

post the codes - a code does NOT say a component is bad, so blindly changing parts is not advised.

Check the wiring to the wheel speed sensor, especially where it flexes repeatedly. I had a similar problem with the wife's Pontiac Montana.
