P1123/1125 cel

[blue62]

I just hooked up my Durametric and checked the Actual values list for the 5.2 DME.
You are correct it doesn't list post cat O2 sensors.
It is a very limited actual values list.


So you could try clicking on the 7.2 DME module and see what readings you get when you click on things like the O2 sensors behind the cats.
Or fuel trims. Just play around and see if it reads any of the values.

But run the test like I said in the post #22 I should be able to tell you if your Pre cat O2 sensors are working correctly or not.

Got side tracked....the CEL didn't pop up again till after almost 1000 miles, no pending either for that matter.....thought it magically went away but it didn't. I'll get those values so we can check the cats. THanks again V
