LOST JEEPS :: View topic - 2006 CRD only reaches 3000 rpm

Sounds like what mine did when I had a split in my driver's side intake hose.

You need to read the stored fault codes. It is in limp-home mode and could have many different causes.

You might want to pull both CAC hoses and check for splits/leakage and try the boost pressure solenoid bypass first though as both are quick an easy and free.

Can someone tell me where the "boost pressure solenoid bypass" is

Also if you floor the throttle it will go to 3000 rpm but will not shift until you let off the throttle.

I'm having the same issues as the original poster.

Right off start it will run fine for a bit. Once it warms up it starts doing the 3000rpm thing.

Shop said its throwing a EGR stuck open code. Options?

It was running fine. I had just gotten it back after the timing belt/water pump/thermostat service.

Maybe now that it can actually reach operating temp its chocking on the EGR crap.??

Is that starting from a dead stop?
How fast are driving when at 3000 rpm?
Are you using a Ram Hemi TCM or GDE transmission tune?

How long have you had your CRD?
Has it always behaved this way?
What was it like before you noticed these problems?

Any idea's on why I can only get 3000 rpm. If I punch it from the start it will bog down at 3000.

Even in park or neutral full throttle is only 3000 rpm.

Green Diesel Engineering. Usually your local Stealership will scan it for free.

Just a reminder that the GDE scanner will read codes stored in the ECU not other places such as the transmission control module (except the generic P0700 ECU code that just means the TCM has stored codes) and the same is true of many/most other readers. DCJ readers will read all codes as will some higher end after market readers. You might want to pull both CAC hoses and check for splits/leakage and try the boost pressure solenoid bypass first though as both are quick an easy and free.

And that little short hose that goes from the air box to the turbo. It needs to be completely removed from the turbo, the failure tends to be under the clamp. If this hose has not been replaced, it should be checked as it is a high failure % part.

no difference with the boost pressure solenoid bypass

This thing runs just fine right up to 3000 rpm where it acts like it hits a rev limiter.

Have you checked the other sensor on your air filter box below the MAF sensor? If it gets loose it has been known to cause issues.

Meh, it barely makes any extra power above 3k anyways so you dont need that last 1k rpm.

I'm having the same issues as the original poster. Right off start it will run fine for a bit. Once it warms up it starts doing the 3000rpm thing. Shop said its throwing a EGR stuck open code. Options? It was running fine. I had just gotten it back after the timing belt/water pump/thermostat service. Maybe now that it can actually reach operating temp its chocking on the EGR crap.??

I dont think the engine would self limit because the EGR is stuck open, maybe its just suffocating because the amount of exhaust recirculating into the intake if it truly is stuck.

What was it like before you noticed these problems? You can have the vehicle in park and rev the motor and it still stops at 3000 rpm. Stock motor, no tunes Owned since new has done this since tbelt replacement before tbelt sometimes it would do this while driving and all of a sudden "bam" it would work like brand new. Like something would pop.
