okay here they are po401 po403 po404 po405 po603 132b p2269 had the 401 two weeks ago pulled egr cleaned it was not very dirty truck is 03 has 135000 on it only problems 3 injectors at 99700 and a icp sensor 1 mounth ago learned how to fix it here from the top can somebody tell me what codes mean pulled them with my hypertec pro i have a actron but it will not pull these it did pull the icp code but i had a cel

 

p0401,p0403,p0404 are all egr type codes,
ingnor the p0603
p132b is underboost this goes back to the egr codes
p2269 is water in fuel.
check your fuel and make sure its good first.

also its always good to provide what year truck you have among anyother info that may help

 

thank you MR cheezit does it mean i have egr problems what should i do , fuel thing fixed got bad fuel cleaned it up

 

ok bad fuel will cause all the codes you have. so are the codes comming back after the fuel issue was corrected?
if they are what codes are comming back?

 

okay first time 401 was there fuel thing started but i new it was egr so i pulled it and cleaned it wif was coming on and was draining it dayly with trash coming out knowing had to change filter but had not come in mail yet ,when pulled bottom one looked like it was caked in mud top one not bad just some jell looking stuf these filters 1000 old ,i change them every oil change 4000 wif light one more time after change small amount of jell like stuff did vc9 flush yesterday coolant filter today pulled fuel filters bottom pretty clean no mud little jell stuff top looked new left them in went to put tow tune in and got codes what do you think

 

there are to many things that it can be that will cause all the egr codes along with underboost codes. could be egr valve, turbo,fuel, ficm, intake leaks, exhaust leaks the list goes on

 

thank you very much for your help MR cheezit
