Just sent a PM.
P11D7 code ?
I have this code come up every now and then. It hasnt posted a CEL yet but its in there when I sometimes check it with a scanner tool. I googled it to death and can only find one thread that says its a camshaft actuator on an Audi. Anybody have any insight.
Thanks,
Scott

Update: Dealer found that the NOx 2 sensor was not installed correctly. Reinstalled the sensor and it appears to have solved the problem ... a relatively simple fix once they diagnosed the problem.
Customer care was a great help in getting this problem resolved.

Wife came home lastnight and said CEL had just come on , so pulled it out of the garage and hit the BLUE button , Dave from onstar came on and did the requested diagnostics. Asked me to write the error code down P11D7, after about 5 minutes he couldn't find what it was so he put me on hold and called GM Customer Care Canada. Doug was most helpful , after 10 minutes he couldn't find the error code , so he suggested that "we" call the dealer. I said sure, he dials through and gets Mike , Mike comes back with an answer . Nox sensor, so make a appointment. Wife shows up early and car went in that was 6 hours ago. Called an hour ago and was told they were still working on it.
Its probably a NOx sensor. The car has a sensor on each side of the SCR. They should be able to figure out which one it is. This is part of the diesel exhaust fluid system. Its going to be a pain in the butt as the cars get older. Fortunately the code doesn't put you in limp mode like the DEF quality poor message. It just puts the DEF system in a max flow condition so its not dangerous. That's my understanding of it. Someone correct me if I am wrong. This Forum provided way more info than the OnStar guy.

Hi, I didn't want you to feel like you are the only one with this issue, after 7500 miles on my CTD my second CEL now, with the first one after less than 10 miles (different code). First one was the P24AE for a particulate matter sensor and now P11D7 which sound like a NOX sensor problem. Going to call dealer later today and see if they will order a sensor BRFORE I drop my car off, the last sensor took about five days to diagnose, order a sensor, and then install new sensor. I sure hope this isn't a constant issue on these diesels with the smog BS. Anyone know how long the emmisions are warrantied for? If its 36 months we're gonna be screwed with sensor problems on these cars in the future or a lemon law issue for sure.
IIRC, the federal warranty is something like 8/80. It's not as good as the 5/100 powertrain warranty unless you drive less than 10K per year, so there is potential overlap. Just out of curiosity, what is the production date on your car?Hi, I didn't want you to feel like you are the only one with this issue, after 7500 miles on my CTD my second CEL now, with the first one after less than 10 miles (different code).

Hi, don't have the car here right now to check production date but I bought it last quater of 2013 so I would imagine Sept - Nov 2013. I will check it tonight and update.
I checked the car at lunch and was suprised to see the MFG date of 4/13. I also called the dealer and got his voice mail. I left a detailed message but 5 hours later no call back yet. The wife picked me up to go to lunch, I was going to stop at the dealer in person but when I got in the car the CEL was now off??? One part of me is relieved and the other side is wondering if I'm in for a lifetime of CEL's and sensor problems.

So, has it stayed off? I think a couple people have posted that they saw this code without a CEL.Hi, don't have the car here right now to check production date but I bought it last quater of 2013 so I would imagine Sept - Nov 2013. I will check it tonight and update.

Hey Sparky you got company. Had my FIRST CEL at 10 miles away from dealer...it was sign I'm sure, turned out to be the particulate matter sensor P24AE. Dealer did same crap, I told them the code but I had to bring it in for a day and wasted my time reset code said everythigs fine. CEL has been on more than my high beams, now at 14,500 I have a code P11D7 which is a NOX sensor I believe(I bought my own scanner). I can't wait for two dealer trips and the loaner 2006 Impala, wow way to smooze the customer. I will keep all posted. I have a post going on my CEL blues. Welcome to the club
I got the poor quality or in correct def. Light with engine light. Stayed on until about 30 miles until limp mode. Shut off by itself but engine light stayed on. I pulled the code p22 Something nox sensor related IIRC I'm on my phone don't have my notes . Then it went off by itself before I could make it to the dealer.
Thanks for the info guys. I just had the CEL pop up On my 2014 diesel cruze with 39577 miles.
When I went to a local advanced auto to read the code their reader said that I had 3 codes. All three where P11D7, with the first one saying "confirmed" the second saying "pending" and the third saying "permanent. "
Looks like it's time to call the dealer!

I got P11D7 last Friday. After about an hour on the highway that night it cleared itself.
Then in today it came back again. We'll see how long it stays this time.
