P132B?
 

I'm haveing this code keep poping up own my programmer. I have replaced the right side y pipe checked for leaks. cleaned the egr valve to make sure it wasn't sticking and the mfs sensor and air filter. I'm running a cold air intake a edge evolution programmer with the stock exhaust except with the cat deleted any ideas would be greatly appreciated. I also had the turbo vanes cleaned to make sure they wasn't sticking

It's usually a turbo issue.

Check this out: Code P132B and turbo noise - PowerStrokeNation : Ford Powerstroke Diesel Forum

thanks for the reply mdub707 I will double check the turbo when i nail the throttle my boost gauge will only go to 21 psi should it be getting hight than that

Usually 22-24 is about right, might be a hair low. Maybe you have a leak on the up-pipes?

If I was getting low fuel pressure would that lower my turbo pressure

Absolutely. No fuel to burn means no heat, which drives the turbo... however I doubt that's your issue, if you had low fuel pressure you'd know it. It would also be destroying your injectors.

I have seen cases before where just simply having an aftermarket intake will cause the code. Do you have the stock box kicking around just to try?

changed the mfs now have no codes showing up and is getting up to 25 psi boost. hopefully nothing else will go wrong thanks for the help

MFS?

Glad you got it fixed!
