Im not sure where your from and if you have these places in your area but this may help you. If you have an Autozone or O'Reilly you can take the truck by one of them with the light on and they will hook up a computer to pull that code. They will then tell you what the code means and you can go from there. I hope this info helps you out and have a great weekend,

The EGR and the lift sensor may look perfect from the outside but the under side of the EGR valve and the EGR passage (small tube) are the REAL WORKING parts.

The carbon inside the EGR passage tube and the underside of the EGR valve must to clean out.

Make sure you has a NEW EGR gasket before you start the job.

It's a 2-3 hours job.

If you do not clean the EGR passage tube the Nox emission will get higher (check you past emission reports).

First. Check the vacum routing from the egr. facing the engine, the vac.
line should go to the right and connect to the egr vacum regulator
solenoid. The line from the solenoid to manifold vacum. The solenoid
is also connected to the powertrain ctrl. module And some models,
have a egr sensor. the two vac.lines from the sensor(if equipped)go to
the exaust below the egr valve. The three wires from the sensor go to the pcm. At this I would plug in the obd2 scanner if no vac.leaks or
bad connections have been found. This can narrow the field greatly.
You can stop by an autozone/napa etc. they will scan it for free.
I hope this helps. Good luck.

Can I by pass the egr on my xterra it does not have the connection on the upper part of the motor

Depends on a lot of things.
1) Does the location of your home have any vehicle inspections that require a state or local inspection?
If so, you are very likely in big trouble.
If not, you might be home free. Maybe.
2) You will need to check with, and make friends with, your local Nissan dealer, to see if the frontier motor had the EGR in another location, so you could still hook it up with longer vacuum lines.
3) By passing the system could at least cause your "Check Engine" light to stay on forever, and at worst, could cause your engine to stop running right, or at all over time, because the computer is set to read the EGR system and adjust the engine to the readings that the EGR tell it to.
4) If all that is missing is that valve, and absolutely nothing else, it might be remotely possible to drill a hold in the upper intake and screw an EGR into it and hook it up, but I wouldn't place any bets on the outcome.
God bless your efforts.

Replace the EGR valve. EGR is Exhaust Gas Recirculation valve and you'll lose a lot of power if the valve is bad.

# 2 cylinder misfire i changed # 2 injector plugs wires roter egr light is still on does the vent breather have any thing to do with this problem nissan frontier 2004 xe

Is this the 2.4L? If so, I bet the Exhaust Gas Recirculation (EGR) valve passages are clogged. Likely has 3 of 4 EGR ports clogged, sending all EGR flow to the #2 cylinder. Check if it still has 8mm plugs in each runner for EGR transition passages. If so, remove those plugs to clean the EGR passages.
Hope this helps. Good luck!

sounds like a problem in the egr valve or the porting through the egr valve or maybe a vaccuum line that has something to do with monitoring it. make sure there are no vacuum lines near it that are leaking and is there a difference in the idle that you may notice.
