I too am having the same issues of the traction control/wrench/abs lights go off and on. I had the codes read and it says c1165 & c1175. Doing some poking around I found those codes to mean that both rear speed sensors are bad. I find it highly suspect that both sensors would go bad at the same time. I followed the wires from the sensors to where they both connect. Wires look good. Any suggestions? By the way, I have an 07 Ford Edge SEL AWD with 59,000 miles. Thank you all in advance for your anticipated help.
