Good morning

What is the code?

What is the information on the truck?

Differential pressure should be around .2 to .8. Beyond that is where a regen is needed.

Cummins 6.7, 2015 International 4300. Initial codes:3376(incomplete Regen), 2639(DPF diff. Pressure), 4713(Fuel Injection Quantity error). One injector bad, replaced.Runs ok but 2639 code returns and it seems regen runs constant. Not that familiar, so shy to pull trigger on new DPF. Pulled Exhaust, puffs on acceleration, but seems clean at speed and idle.Diff. pressure goes up to 10 inHg at speed
