05' dodge 1500 5.7 EGR issues

[DrDusty86]

My dad's truck, an 05 1500 5.7 has a check engine light for "high EGR input pressure". The truck has 70k on it. Can these be cleaned or does it have to be replaced?
Is this a major problem with the 5.7 Hemi, or just a fluke?
Thanks,
Dusty

Might want to ask a reputable Dodge forum.

I had to replace mine at about 80K on my 2004 Ram. I paid 40 something bucks at autozone.

EGR valve failure is common on chrysler products, particularly on the 3.3, 3.8 and 5.7 engines.

 

[DrDusty86]

can you do a bypass like on the 6.0 PSDs?
I don't want the issue to happen every 50-70k Bypass or delete and be done with it.
And if it's anything like the 6.0psd it will run 10x better once its capped.

No, its not anything like a powerstroke. You will have an eternal MIL if you try to bypass it, even if you can. Just replace the valve, they are short money.

The 6.0 PSD is nothing like the 5.7 gas engine.

 

[DrDusty86]

Is there a better aftermarket valve like autozone or osmileys?

You can always replace the valve and then delete the EGR with a tuner.

Matt thinks thats not a good idea. If it was a PowerStroke I'd have done that already.

It's what I was thinking though... I'll do more research on it and see if it can be deleted safely.

I think Matt thinks you mean "delete" by removing it. Which of course will cause the ECM to have a seizure.

On the PSD, you could delete it, unplug the sensor, and not ever get a CEL for it. This is not the case for a gas engine.

If however, you remove it (properly) with a tuner, you can leave the valve in place, so it "looks" legal, it just won't be functional.

 

[DrDusty86]

interesting... Will affect the drivability of it?

 

[mattd]

No. it will completely disable it, and if done properly, should go undetected. The only issue is that if your state requires an annual inspection, i'm not sure how the EGR monitor will look to the inspection computer if disguised with a tuner.

I used to bypass EGRs all the time.
They were overbearing and crude. Part throttle response and power was always better.

But on newer cars, things have changed. They are more sophisticated and better.
The EGR makes you engine less efficient, but that can be GOOD when cruising. Your engine acts smaller than it is, and requires more throttle for less manifold vacuum. Less power to run! And of course it DOES lower combustion temps to allow for more ignition advance when cruising.

I don't know your specific car. They are all so different now!
You can try a cleaning, or get a new one if that does not help.

Common issue for the 5.7L Ram's. Cheap to repalce and easy to do. Just replace it.
