I went over to Wild Diesel and talked with them showed him my truck he explained to me that the air intake elbow only has a 1 inch hole in it. He said if I change the elbow out get rid of the tube, the unneeded vacuum lines and block off the exhust manifold the code should go away. I am going to do it and will post my results. It will take several weeks, going on out of town for a couple of weeks.

 

My EGR had been removed before I got my truck, so if anyone still has one could you please measure the resistance across the contacts my thought is if i place a resistor in line i can clean up the code.

 

hey TJ cummins the only wires on mine go to the Vacuum Regulator Solenoid is that what you want me to test.

 

Is that what comes off the air horn and is there a two prong wire plug in coming off of it. Sorry mine has been removed so i have nothing to go off of. Thanks for your help

 

TJ Cummins I have no wires going to my air horn. a guy from wild diesel told me to jump the wires with 10 ohms I was going to use a resistor don't know what wattage to use, a few watts suld be good. mine didn't have the wires so, I took my truck in and he said to just remove the old air horn with a new one thats not restrected. I will try it in a few weeks.

 

Thanks. I tryed a 10k resistor and did not work. So I talked to the cummins shop locally and they need the block number and we see as to what type the EGR is. I will let you.

 

TJ CUMMINS Hey Vacation is over I took of my intake air horn, the cross over tube, pluged the exhaust manifold, and removedall the vacuum lines with the EGR Valve Vacuum Regulator Solenoid which is where the plug with the two wires goes.
as soon as I started the truck it gave me a code P0403. I cleared the code and pluged back in the EGR Valve Vacuum Regulator Solenoid and the code went away. that part is what opens the vacuum lines going to the EGR valve. the ohms between the two leads is 46.6 ohms
I will have to run the truck to see if any other codes show up. will let everyone know what happends.

 

Monstercat thanks for the info. I was told to unhook the batteries and it would possibly reset but the only thing that did was to clear my radio channels. Thanks for the pictures it helped a lot. I will try a 47 ohm resistor and see if that will do it and get back to you.

 

to clear your codes you can go one of your local auto part stores and use their code checker and clear the codes after you put in the resistor

 

So did you put a 47 ohm resistor in line and then cleared the code. That's great I will try it. Thanks TJCummins
