Check Engine Light P0299 - How to check a Turbocharger

This video shows you how to do some basic checks and different ways that a turbocharger can fail. This is on a 2013 Chevrolet Cruze 1.4L engine. Check engine light was on with a P0299 code stored in memory.

General Overview

  • Test drive vehicle to check for symptoms like loss of power or torque.
  • Use a scanner to diagnose codes in the memory, or an active code if the check engine light is still on.
  • You may need to remove your turbo to check the wastegate solenoid, etc... The catalytic converter will also have to come off.
  • In this instance, the whole turbo had to be replaced because of a crack in the turbo housing and a rough wastegate that wasn't closing all the way. This was causing essentially a vacuum leak and and generating the P0299 code.

Video Transcription

"Alright, today we're working on a 2013 Chevy Cruze and I was told that the check engine light was on. But as you can see as you can see the check engine light is not on here. Let me turn the key off. See the check engine light over here. But um, when the cars running the check engine light is on.

So what I'm going to do right now is I'm going to take it to the shop scanner for a code, see if there's any codes in memory. And then we'll go from there. I'm also going to go to test drive and see how the car feels. See if I feel anything.

It's almost like it has a restricted cat converter or something. Something that feels, it just feels weak. It feels like it's lacking power. I know it's only a four banger, but I think we will verify that and then we'll see what we can find.

Alright, so I got my scanner hooked up. And real quick, I just want to know if there's any codes in memory. So I'm just going to use my actron scanner. And we're going to go global because let me show you. Let's say that I want to pick a 2013 Chevy, my scanner, won't allow it. It only goes up to 2004. And after that it goes global. So 2004 newer, it's going to go into global, so I have to keep it there.

Just OBD is all right. So let's just go ahead and scan it and see what comes up? All right. Oh, we got one cold... Look at that. All right, here we go. It's a P0299 turbo supercharger under boost. And when I was driving it I did feel a little bit of hesitation lack of power. So this does make sense but I don't understand why the check engine light wasn't on. Maybe the light just came on and then it's like a two trip fault or something. So we're gonna have to take a look at the trip.

So the turbo on this car is right here. It's part of the whole exhaust manifold assembly. And usually what happens is this lever right here wears out and it causes a wastegate to stick open when it's supposed to be closed and that'll give you a P0299.

I'm also seeing it where it cracks, it cracks on the inside. By the turbine, but uh, we don't know what's wrong with it yet. So we're gonna have to take it apart, open it and see what's going on.

These are the exhaust heat shield, you're going to need these. It has these inverted torque sockets. So you're supposed to use key and turn it like that. But if you guys don't have any you can use a regular eight millimeter socket, and it's going to take it's going to take those nuts off. It fits perfect in there. So let me go ahead and remove that turbo for you and then I'll show you guys what's going on in there.

Alright, so the catalytic converter had to come out. You can see what's left up there is just terrible, right? I can already see something here that doesn't look quite right to me. I don't know if you guys can catch it on video. But once I take it out, I'll show you exactly what's going on and what's wrong with the circle.

All I gotta do right now is take off these two both right here. And let's drain the oil and then I think it should be good to come down. So let me let me take that off and then I'll bring it down for you guys.

I remember what I told you about those was torque. Sorry, not torque inverted torques. I'm just using the regular eight millimeter socket. Take that off. It works fine.

Now originally the problem with it was this here. I looked it up on GM and according to that, this crack, it's normal. Now, another thing that I found was that the wastegate was pretty rough and there's a brand new one over here. It's way quieter, smoother and it's just not binding at all. So that's how I supposed to be.

So what I'm thinking was happening with this one that there was a point where I will get stuff open and it will start leaking. So That's where the P0299 came from. Right here. It doesn't go by the way it'll get stuck. Essentially what you have is kind of like a vacuum leak.

There it is guys, brand new turbo assembly installed on a 2014 Chevy Cruze. Now I know I didn't make this a how to video how to replace the entire turbo assembly step by step. And that wasn't the plan. That wasn't my intention with the video. I just wanted to show you the fallout second happened with the turbo assembly. One thing I didn't mention is that this thing right here could also be bad, because this is the one that controls back into this actuator. Right now our problem was in here, and it wasn't with the turbine, that turbine can go loose if the bearings go bad inside of it. Our problem was with the wastegate solenoid valve, it was opening. And when it was time to close it, it would bind and it wouldn't close all the way. essentially creating like a vacuum leak in the turbo assembly.

And that's one of that P0299 came from. But honestly replacing that whole turbo was not difficult. It is time consuming, though. But if you have one of these cars and you have that P0299 most likely you're going to have to change the whole turbo over here. That right there is a catalytic converter - that's gonna have to come off separately. I think I showed you guys in the video.

But um, right now what I want to do is go test drive the car and make sure that everything is good. Make sure that we have proper acceleration and proper boost and make sure that it just feels good overall, you know. I'm going to go ahead and take it on the freeway and make sure that it pulls nice like a four banger with a turbo should. The gears already slipping so this thing's pulling nice oh yeah this thing has a nice nice cool sorry about the shakiness but I'm on my phone and it's hard to record while driving too so. Oh yeah. Alright guys, that's gonna be the end of this one. Thanks for watching hope you guys learned something, give it a thumbs up. If you haven't subscribed to my channel yet, go ahead and subscribe."
