Pontiac G6 ABS Problem

The Car: 2006 G6 V6 Sedan 49,000 miles

The problem: Driving home 150 miles through an intense snow storm I seem to have developed an intermittent ABS issue. I stopped at the store just before getting home and when I re-started the car the "ABS" "BRAKE" and "traction control" lights came on. I have purchased a scanner and found there are 3 codes, C0050 Right wheel speed sensor circuit, C0045 Left Rear wheel speed sensor circuit, and a history code for C0281 Dynamic rear proportioning performance.

I find it hard to believe that both rear hubs went bad the same day, Does anyone know of a common element that could cause this issue. Perhaps a shared ground somewhere. It is also intermittent, when starting the car sometimes the lights do not come on and the scan only shows history codes. The times the lights do come on I do not hear or feel the ABS test cycle run.

Any help or advice would be appreciated! If anyone has a wiring diagram for the abs that would also be helpful.

When the ABS light comes on you will not hear or feel anything cause soon as the ABS light comes on the ABS is disabled
sounds like it is weather related (rain,snow)
i would check both rear wheel speed sensor harnesses for water intrusion if you see any corrosion (green) on the terminals replace both the hub and harness
if there is no corrosion then check resistance of the sensor also check for a short to ground
if that is ok then put some dielectric lube on the wheel speed sensor terminals and clear the codes and see what happens
intermittent problems can be hard to find
hope this helps

I have the same problem as you, with the same car. It seems to be moisture related. Mine is two months out of warranty, so I inspected the rear wheel speed sensors, like your dealer said. There is a TSB (technical service bulletin) concerning this problem, so Toyota/Scion do indeed know that these sensors are failing. In my case, one of the sensor connectors was broken when the car was assembled, which bent the tiny sensor pin, which broke off while I was attempting to get the connector plugged back into it. I make my living as an electronic technician so I'm not inexperienced with such things. Anyway, rumor has it you're looking at over $700 at the dealer to replace one sensor, since you cannot replace only the sensor. The part (rear hub assy) can be obtained online for $290, plus the wire for $37. All in all, it's a crappy situation. A known problem concerning key safety systems on the car, and Toyota neither issues a recall nor do they extend the warranty.

You may have ice build-up in the brakes casusing the ABS to engage- [ the traction and service light will both come on with the ABS. Check to see if you have ice.

2008 Pontiac G6 winter driving the car seems to slide in the rear and is not easy to control.

It's possible that your Front/Rear alignment is way out of whack. Have the car undergo a full front/rear allignment (~$80 USD) or your rear tires are below spec.

sounds like your front end is worn out and yes tie rod ends are a common source of this problem along with out of balance tires and seperated tire cords, any tire store will inspect your car for free and give you an estimate to repair.
