  3. Gen1 Diesel Technical Discussion
    Hey all! New member here, so if I'm not posting this in the right place, please let me know. I've looked through several threads on the site and haven't seen what I'm looking for, so I'm hoping I'm not repeating something that's already been asked. The other night I was driving home and got a...

    I was playing with a scan tool today while driving and was trying to find a way to check my def tank level. Normally the DIC shows "OK" until around 34-36% before it starts showing a number. Right now it just says "OK". So monitoring while driving it showed my NOx reagent tank level at 100%...

    Hey there. So I recently went to Chevy to get my CEL diagnosed. And the technician told me that the code was for the Nox #2 sensor this time. And I’m just wondering if I have to get that replaced before I do a DPF delete or not. Because I don’t want to spend close to $800 to have that part...

    Well I was on SI today trying to diagnose an issue with my remote start when I saw this memo that was issued today. For the record I had my dad do mine and have not had any issues. I am going to leave the current ECM program in my car unless I have any issues in the future. PS I think my remote...

    Seems like a lot of people are having a check engine light after getting this recall done. I wanted to create one thread where we can all post our experience and updates. I got a P11DC within 650 miles after getting the recall done. I am going back to the dealer for followup and will report...

    I have a 2014 Chevy Cruze Diesel with about 46500 miles now that recently the check engine light comes on with codes for the NOX sensors. I know one code is P11DC read by ONStar. The service guys had some other codes too but the problem is with the NOX sensors. They have replaced number 1...

    1. Idle MAP can now be under 14 when it is NOT in a pre-regen state, (but not always). This one concerns me because now there's no way to tell when the car really does go into the pre-regen state. And no, a regen was not in progress. 2. The number of completed regens was reset to zero. 3...

    So I noticed last week I took my car to the dealer for the nox sensor recall, dropped it off. They called back and said they had to order the part so I picked the car up and was fine till the other day I noticed the heater wasn't working looked like due to lack of coolant, so yesterday I topped...

    93 minutes from the time I stepped out of the car until my butt was back in the seat. I had pulled into the dealership unannounced with no appointment just to check on the status.

    Hi all, I am now on my second CDT, the 2015 model. As with the 2014 model, after about three months the nox sensor went out. The dealership here would have to jump through what ever hoops that GM puts them through, just so they can prove to GM it is the nox sensor, and order another on...

    The repair for NOX Sensor #2 is identical to the replacement instructions for the Particulate Matter Sensor with the following amendments: 1. NOX2 is the forward of the two sensor bodies. 2. The sensor module for NOX2 is to the rear of the Fuel Filter (as opposed to the module for the...
