P026D Code & Injector Values

[daigljk]

I am getting the P026D CEL code (Fuel Injection Quantity Higher Than Expected). I used jscan to look at the PID "Total fuel correction" for each cylinder. My understanding for an injector operating within specs is for the injector to be as close to Zero as possible in terms of total fuel correction. Can anyone with jscan post what their PID "Total fuel correction" values look like. I'm not sure what "normal" is supposed to look like.

23 JTRD with 18,000 miles

Thanks!!

I had a p026d on my Duramax. It ended up being a fouled nox sensor. I think the Ecodiesel works the same way. Maybe a Jeep diesel guy can confirm. Look at nox values.
