I have 2 of these gen 1 Cruze Diesels, and oddly there is different behavior between them.. for reasons I'm still trying to determine. The one I bought used had had P0133 a couple of times now, I reset it and go.. but after the second I read about soot on the sensor, turns out it's easy to get this sensor out to inspect. It was very soot covered. I cleaned it with brake parts cleaner and blew it out with compressed air. Total time for this was less than 30 minutes. I also blew air into the manifold, which produced a small cloud of soot. I've not had these issues on the other car, and it gets better fuel economy as well.Got the following codes on the way home Friday night:
P11's are for the NOX, P0133 is O2. Back to the dealer next week. 66K miles on the clock. Seems like I get a CEL every 8K or so.
I really like this car, but I'm done with going back to the dealer every 4-5 months. No interest in deleting the emissions system, not my thing. The car should run as designed.
It may be my driving habits or the amount of stop and go traffic I sit in everyday.
I'm trying to decide what to do with it after it is repaired. Financially I don't really want to buy a car right now, I'm about 12months away from having this one paid off. Deals are to be had on new cars for sure.
In your case with all sensors giving you issues.. it could be a damaged DPF, my other Cruze had a bad DPF from new, replaced under warranty in the first week. It permitted soot to pass. That with stop and go, perhaps a sticking EGR valve and that could be causing your issues. On my Cummins truck I can just unplug the EGR and it runs fine, I'm not sure if that I possible with the Cruze, might try it if I continue to get extra soot on that car.
