Customer Question

I have a 2008 Dodge Ram 3500 6.7 turbo diesel Dooley . It doesn't accelerate with full power at any time and it has a constant muffled noise coming from the air filter housing. I did a code read and got these codes P0487, P0405, P0037, P2504, P063D. What do you think?

Hello. My name is ***** ***** I will be helping you today.

Check the 5 volt power supply on pin 1 at the EGR Control Valve Connector, then check the sensor ground on pin 5.
