2014pinnacle Posted 7 hours ago Author Share Posted 7 hours ago I cleaned it when I had it off submerged it in egr system cleaner over night and rinsed it really good. It’s not over heating and seems to have plenty of of power Quote Link to comment https://www.bigmacktrucks.com/topic/76269-p0403-egr-code/page/2/#findComment-590639 Share on other sites More sharing options...

Check the intake manifold for missing or loose bolts and cracking lower front! Thats the last of my ideas on this I am not a guru on the subject ! just observations over time! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76269-p0403-egr-code/page/2/#findComment-590653 Share on other sites More sharing options...
Joey Mack Posted 3 hours ago Share Posted 3 hours ago fjh has a point about the plastic intake manifold and broken bolts. the intake gasket is a joke. you will see if you ever have to remove it.

2014pinnacle Posted 2 hours ago Author Share Posted 2 hours ago How long are the Venturi tubes when I cleaned it before I put the new pressure sensor on the holes were plugged solid I cleaned them out and was able to force a bore brush down into the tiny holes does that go right into the egr pipe or do these run along side it?

Yup another bone headed design by some no mind ! Same as the asshole pipe discribed earlier !volvo trash! The base design of this engine is pretty stout however the bolt on stuff not so much! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76269-p0403-egr-code/page/2/#findComment-590658 Share on other sites More sharing options...
