Hi. I am having a problem with 6.6 2007 Sierra Classic, there is a hard code P0107. I have installed EGR stick from PPE and also electronic boost control. The dealer tried to help, but after 100 feet truck goes back to limp mode. He told me to get truck back stock and he will fix, but before I would like to fix it with the upgrades... if there is anybody knowledgeable I will appreciate any help. Thanks

 

Welcome...I cant help you but Im moving this for better exposure.

 

It would be a huge help if you would go into your User controls and fully fill out a signature for us.

Let me try and research this and see what I can find. It appears it would indicate an overboost condidtion.

 

did you block you egr too when u fingerd it?

 

Do you have a boost gauge? What are your readings? I've read that you can set this code with a boost controller if you go above 28psi.

 

i would go back and make sure all your connection are good you would be surprise how a connector that looks good may not be i had one wire loose once and my truck wouldn't even start. start at the MAP sensor that is what the code is from

Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage, this is what the code is

 

Any Updates ?
