Turbo Down!?

Just yesterday my CEL turned on while I was driving around downtown. No noticable problems were arising so I decided to drive my vehicle home. While out on the freeway I noticed a devistating fac: it seemed as the my turbo was not working. I was driving 100 km/h and tried to speed up to 120 km/h. The RPM gauge was showing that I was reaching just over 3000 but I was not speeding up at all. I tried it again when I slowed down to 60 km/h and was not as bad but the turbo was not being very productive.

Once at home I looked into this problem, maybe a turbo hose blew, but everything looked. I felt around and nothing was out of place.

Could the problem be the turbo itself? Maybe an internal part or something?

Thanks to all that take a second to read and comment on this post.

Peace. :ALONE:

If you can pull the code, we will be able to help root cause the issue. Thanks.

There is no code from the electronic odometer.

Most likely the CAC hose, unless you removed it and looked at the bottom, you wouldn't know for sure. I have no idea what the last response means.

Try tightening up your hose clamps. It sounds like your losing abit of boost, not enough to go into limp mode. A boost gauge would tell you but you don't have one. Definetly inspect your turbo hoses, but start with the clamps.
The other thing that can cause a mild loss of boost (and there have been a few of these lately) is a hole in the intercooler, but this would likely really only be noticeable as a slight reduction in full power acceleration (depending on size of the hole obviously).

One advantage of a Boost Gauge is that you get verification that all is well every time you accelerate. No boost, check the hose first, they rip or blow off the fittings. CRD hoses like to blow on the bottom side where you can't see the rip. I run my hand under the bottom of the hoses just before where they attach to the fittings. If they feel too soft and gel like, they are ready to burst or rip, so it is time to break out the Credit Card and order a new set. Provent, a good Home Made Oil Separator, or the EHM will eliminate the hot oil mist that destroys hoses. Make sure you transfer the old braided wrap or install a new on the hoses where they can rub and wear a hole through them.

Back before the introduction of quality hoses like Samco's, I had to use over the counter radiator hoses which were not as good for my custom turbo installations. Back in those days silicone hoses were expensive and hard to find, so we had filler neck hose and metal pipes when they could be used, or we used formed radiator hose and made them work. Still, I used them for years and got by with them. Keep the oil off and the hoses will last longer.

Turbos do not go bad as much as some would like to have you believe. A properly designed and used turbo should last the life of the engine and may go longer than the first set of rings and valves. If the turbine does not wobble excessively, the blades have rubbed on the housing, the veins stuck and can not be freed up, or oil is dumping out of the center section, chances are that the turbo is still OK. Some suppliers love to sell turbos and other stuff that is not needed, others sell performance upgrades. So, if you want a turbo that doubles as a jet engine thruster, better plan on having a larger than 2 1/2" (64mm) exhaust and put the pipe in the middle so it does not make the KJ pull to one side. :ROTFL:

I don't think it's the turbo.From what I've gathered,it either works fine or craps out.No inbetween.

Sure is sounding like a split hose,or leak in hose due to loose hose clamp.Is there any sign of oil blowing out by the hoses where they meet turbo/intercooler/egr?

So I took the hoses off this morning and all was well. I re installed and made sure all clamps were tight. I then went for a 20 minute drive to my place downtown and the CEL never showed up. How happy I was. However, on the way back the engine light turned on with only a few km before my destination. :banghead:

!!!!!!

I have just tightened hoses again but to no avail. Light is on for good I believe.

Thanks for everyone whom responded. The hoses may be the problem and I will look into putting a new set on. Until then, I will keep looking for other solutions to the CEL. :5SHOTS:

If you go get the codes pulled, we might be able to help you out more. I believe autozone will pull them for free.

What is the device called that you can pull the codes from you vehicle with? I would not mmind finding a store that carries one in town as it would almost be usefully on a weekly bases. I do not think there are any autozones in Edmonton, AB, Canada.

It's a code reader or an OBDII Scanner. Not all models of these devices work well with the CRD, but I'm going to have to leave it up to others on here to recommend exact brands. I don't own one...

In the meantime, call your local AAMCO - I see two in Edmonton. Their website indicates that they give free CEL scans, though I don't know if they try to tie that into paid service as well. Call and ask if you can come in and have them just pull the code(s), nothing else.

Princess Auto http://www.princessauto.com/ may be able to help you, they have two stores in Edmonton. I have used them when I have been in Canada. Their prices are fair, plus they have lots of tools. When we needed a 10 ton hydraulic ram and could not rent one anywhere in the Greater Toronto area, they had them in stock. Since I could not ship it back to the USA, I had one of our Canadian Sales Rep Firm take custody in case we (including them) ever need it again. That way they could not charge me with bribery for giving it away. The Suck Foreign Corrupt Practices Act could burn me if I buy one too many boxes of Tim Hortons donuts, so I count heads first.

Good luck

So....

I changed out the CAC hoses and was pretty excited about the possibility that this would solve my CEL concern. I will not say I was devestated that it did not, but I was a little unhappy about the situation. SO.....

Now I have new hoses and the CEL still on. Does one maybe have to resent the CEL so as to turn it off after the problem is solved? Or ill the CEL automatically turn off if concern has be dealt with? Is there anything else I can check before I am forced to send my Jeep to a dealer for the 8th time since I bought her (Sept. 9, 2009). :banghead:

Thanks for the opinions that are reached out towards my concern.

Peace.

It may take a couple of cycles for the CEL to go away on its own, if the problem is fixed. I've only had two CELs, one went away as soon as I plugged the sensor back in and the other hung around for a day or so. Not sure why the difference...

Can you stop by an autozone of other auto parts store that could do a quick scan of the codes? This would most likely be a cheaper option than the dealer.

linewarbr · **Posted:** Tue Aug 10, 2010 10:29 pm

More important than the CEL is: how does it drive now? Has changing the hoses seemed to fix the problem?

If not, I would suggest pulling and looking at the MAP sensor next.

Untill you know what the error is your just throwing money down the well :2cents:

Fuel Filter is clogged...... If you don't want to replace your filter then add a lift pump.

I experienced the same issue and I thought the problem was with the turbo or the transmission at first but it turned out to be a clogged fuel filter starving the fuel pump during high demand (higher speeds)

+1 Sounds a lot like what I experienced when I clogged a fuel filter.

This doesn't have anything to do with the CAC hoses. I had this same problem a few weeks ago and posted about it. Jeep lost all power upon leaving a red light, CEL came on, drove like crap. I tried to pull the codes and got P0039 and P0513 or something like that.

After a few cycles, the Jeep turned the CEL off on it's own, and drives fine now. Some set point in the ECU was passed by excessive boost and the ECU shut down fuel to protect the engine and turbo...that's my guess. In other words, the Jeep went into limp home mode.

Turbo Down!?
