Cel p11dc

At 22k miles I got this code. I couldn't find it on the internet. The dealer said it is a leaking air cleaner duct. They replaced it no charge. I'm hoping the light stays off.

Is there anyway that your code was a P11D7 instead of P11DC? I ask you because I have got this code a couple of times in the last 35K miles. I bought a code reader soon after a couple CEL's right after I bought the CTD to avoid the dealer visits.
P11D7 is a NOX sensor calibration signal problem. I cant help with a P11DC. Sorry.

Great. Thanks for the follow up. Did you notice any fuel type smells in the car especially at idle ?
