How to change the VGT solinoid?

[CrystalCreek]

Title says it all. The little solinoid on top of a 2004 turbo. What is involved in changing it. Code reader caught a code that said it is not working properly. Thanks in advance. Hopefully it is something simple to change.

With the truck off unplug it and make sure the contacts are clean on both ends. Maybe spray a little brake cleaner in them to make sure they are clean. Hit them with some dielectric grease and plug it back in.

If it was working before you unplugged it it should still be working. It may just be showing the CEL because you had it unplugged. Can you reset your CEL and clear the codes? SCT or an Insight allow you to do that. If not have an AutoZone or similar do it for you.

I will try this and see. Do I have to unplug the battery to clear everything up and start the truck as fresh?

Not if you have a way to clear the codes like with an SCT device or an Insight. You can also clear them by disconnecting the batteries for 20 minutes and letting everything reset.

Dude, you are awesome. Thanks for all your help again. I will clear all codes by way of battery. Thanks again. If I still have the same code then I will ask for the VGT solinoid replacement procedure. It looks easy, but every time I think that its always ends in disaster.

If you do end up changing it--it is very easy to do, just unplug it take 1 bolt out with the little bracket and just pull out and replace. It only will bolt up 1 way so I dont think you can screw it up.

His solenoid isn't bad, it's just throwing a code from having run it unplugged in an experiment.

Actually since it works now if you just drive it it should see that it works now and reset the light itself. Might take a while though.

I don't see any experiment said on here but he could also have sticking vanes.

Were you going for the super loud turbo whistle? Bad news.

That was in a different thread. He wanted to know if he put a smoke switch in and threw it at idle if it would quiet his turbo whine. The answer was yes but it was a bad idea and would smoke a lot. Some people in that thread seemed to think it wouldn't be a big deal so I told him if he wanted to see what it would do, set it on hi idle and pull the plug off the VGT solenoid. He did and found out it smoked way to much.

Now he has the VGT solenoid code from having it unplugged. All he needs to do is reset it.


All the facts weren't presented here to diagnose the problem.

Nicely done!

Plug it back in and drive.
