Anyone else received these codes? Car is bone stock with 19k miles on it. I cleared them once and they take about 2-3 weeks to come back. Normally they come back when I am sitting at light. I feel a slight bump and then CEL showing these codes.

Any help would be appreciated as I have looked all over with very little luck. My only idea is to replace the VSS at this point since I found a thread that said that was successful in clearing this up.

Thanks. I figured out what the codes were but I am more so looking to see how people were able to fix them. I have seen everything recommended from replacing the VSS, the trans, bad grounds etc.

 

So this code comes back every 1500 to 2000 miles. It's really strange. I did a bunch of searching and others have had this problem but no one has posted a fix. It looks like the simplest option is replacing the input speed sensor. Unfortunately this requires removing the valve body but it's a good first place to start. The sensor is $20-40 depending on where you get it. I guess I'll order the part and go from there. It also looks like there is a special tool required to take the valve body out.

This thread mentions a Camaro with the same issue. He cleared it. Car drove fine then it came back. The dealer replaced the sensor and it corrected the issue.

 

I figured I would update this now that I have installed the new sensor. All is well. The install was kind of a pain with removing the pan. There are one or two bolts that are hard to get at. Otherwise its pretty straight forward. I used AllData to guide me through the process though.

 

Thanks for the update! I just hit these same codes on my 09 C6 Corvette A6 with A&A kit+meth....If stock cars are hitting this then maybe it's not just because of the extra power, I'm hoping anyway...
I've cleared the codes and waiting to see if they come back.

I hear the sensor is on top of the diff? If so, the trans needs to be dropped down?

Thanks,

the same codes have happened to me 2 times now. Both times I noticed that my temp had just passed 220 stuck in traffic. Being stuck under 2k until I turn it off, disconnecting battery has fixed it until I get stuck in the Texas heat again. do you know which sensor they needed to replace to fix it?

 

Seems to be the VSS. I've been lucky so far; I changed the trans fluid and filter, cleared the code, and hasn't com back yet.

Maybe someone else can chime in. Good luck.
