I'm having an issue with my C6 after having the driver rear wheel hub assembly replaced (it was replaced due to it going bad and howling loud). I did not have any codes or issues with the sensor before the replacement. My C6 gets driven daily.

A couple weeks after it was replaced and on a drive, i went over a speed bump and the car chimmed 3 times and service ath, abs, and traction control was displayed on the dic as well as some lights on the dash. I turned the car off and turned it back on and it all disappeared.

A week later it happened again. Now worried, I plugged in my scanner and the code was for the driver rear wheel speed sensor. I deleted it, cleaned the connector and all was good for a couple weeks. I ended up moving to a new state, drove about 300 miles for the move and did not have any issues with it.

It's been 2 weeks since the move and I have not had any issues till tonight. All the lights and dic warnings popped up and the code was for the same wheel speed sensor. It happened going over a rough patch on the road. This issue has been extremely intermittent. I've had weeks of it not happening even when going over bumps and rough spots on the road. It happens randomly and can't easily be replicated.

I'm not sure where to go from here. I would hate to have the hub assembly replaced again. Thanks-Bliss

 

Not only should you clean the connector but do a terminal tension test or pin drag as it’s sometimes called…video below.
