New to the Forum - Wrench Warning Light??

[ratboi]

First I'd like to say I am new to the forum. I just picked up my dad's truck this morning and drove it from New Mexico to South Orange County. As we were driving the last 25 miles going up a large hill from the 91 to the 241 we hit the pedal down to climb the hill, the boost went into red (40psi) then the wrench light came on...seemed like loss of power after that. Got home, turned the truck off and let is sit for a while. Turned it back on and the symbol was gone but it just doesn't seem right. And now at idle there is a loud rattle.

I am new to a diesel truck. I've owned subaru's all my life, so I'm familiar with turbos, but this is a whole different animal to me.

Any help or suggestions would be very helpful.

Thank you

Your PCM probably detected what it considered an over rev condition and immediatly defuled in an attempt to keep you from killing your own truck. When the wrench light comes on you are in limp mode and uses a default set of settings overrideing any external input commands such as throttle for one.

Ok, I figured it went into limp mode. Just can't figure out what the rattling is now...

Thank you.

Disconnect the boot off the intake side of the turbo. Look if thereare any signes of something broken. Check for side to side and up and down play of the turbin wheel it should be very little. Normally measured with a dial indicater in thousands of a inch, so don't expect much movement. See if it spins freely by hand, observe if it rubs or if ya hear rubbinng from the ehaust side. Check the exhaust side in the same way.

I suspect something has let go in the turbo or bearing failure.
