My diesel Cruise came up with the P11D7 code (nox sensor).
The service man thinks the Scan Gauge might be doing something to cause the CEL. Is he nuts?

Does it have a tune?

I don't think it did, I think if I get any CELs I will just take the scan gauge out of the car. Seems nuts, it is just reading information and displaying it. If they had designed the car with a regen light or something of the sorts I would never have purchased a scan gauge

I highly doubt your ScanGauge caused a CEL.

The NOx sensors have been a recurring issue with the CTD. Your scan guage didn't cause this.

Dealers will blame anything and everything on something they see that is aftermarket even if it clearly has nothing to do with the issue.

This is no joke, I once had a Toyota dealer decline warranty work on my transmission, on the paperwork I received one of the reasons for the denial was "aftermarket radio".

I don't take my vehicles to the dealership with so much as a different license plate frame anymore.

I currently have the same CEL and a scangauge 2, but they are not related. I've had many CELs prior to my SC2. The light came on a week and a half ago, then went out, then came back on and then went out again. I'm watching it before I seek further action.

What's the condition of the flange by your SCR? Several people including myself have significant corrosion with at least two people experiencing broken studs there.
