Question about 2005 Chevrolet Uplander

1 Answer

Where is the EGR valve located on a Chevy Uplander? I was thinking of disconnecting it, my van is running very rough and blew the code on it. Hoping this will be best option, or is it that important to put in a new one???

    what is the code. is it for flow if so you need to clean out the egr ports in the intake manifold behind the throttle body.

The EGR is located on the intake at or near the throtlle body. DO NOT !!!! Disconnect, the car will only run worse. I recommend you locate it and either replace it or just soak it in cleaning solvent for a couple hours and then clean the carbon buildup from inside the dirty side (the side that's black or dark grey) with a long, thin blade. Blow it and dry completely and install with a NEW gasket.

05 uplander when i start the van runs fine, i go to drive have no power, throttle is spongy. when i hold the throttle to the floor it takes off with great power and then it runs fine from then on ,


For an EGR code, I would have looked at the EGR valve, wiring to it, and the catalytic converters first. The only other thing I can think of is the programming for PCM. I think you may have a wiring problem, keeping the EGR valve or throttle open. You need to find another shop to go to. You should complain to the shops you payed good money to, that didn't fix the problem. Get your money back. I'm not a point and guess car electrician. I get 2 hours to diagnose. 2 hours shop rate. I have a 95% success on fixing problems. The first time. The other 5% is major wiring issues.

Where is the egr valve on a 99 Ford expedition


The EGR valve is in a very difficult spot to work on. If the EGR is bad it will set off the check engine light and make the vehicle run rough or stall at idle. It really doesn't make it run rough while driving or accelerating. What are the conditions when the car runs rough?

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

Ford e150 codes: p0401, p1401 and p0174. read the more details to see what the symptoms are.


Stop, DO NOT replace expensive parts or O2 sensor! Ford Explorer codes p0174 , p0401 , rough idle and check engine light on. First thoroughly check all of the hoses and elbows connected to the intake and EGR (vacuum system) for splits, cracks, holes or tears, this could quickly cause these codes and fixes for less than $10. Check all connectors and the EGR valve sensor it could have a crack as well, inspect thoroughly because a split sensor could appear attached to the vacuum hoses but hoses could just be sitting there not actually attached due to a split or crack. This was my problem replaced the EGR valve sensor and the two little vacuum hoses attached to them for $50-60 with in stock parts at the local parts store. Took less than 10 minutes to replace and is easily accessible, the check engine light turned off immediately without having to reset the codes by disconnecting the battery, idle became normal and fuel efficiency better. If you have THOROUGHLY inspected every hose, connector and elbow and found no issues, clean the MAF with electrical contact cleaner ( let dry) and clean the EGR with carbon cleaner. A dirty MAF or EGR could also cause these codes to pop up. If this still doesn't work, then consider replacing the EGR, if that isn't it then try the O2 sensor. Good luck!

95 chevy van g20 starts runs rough and when you step on gas it stalls


I recommend checking the EGR valve first as GM cars and trucks of this era are famous for small ckunks of carbon getting lodged in the valve seat and holding the valve open causing rough idle and general undriveability.

2006 Dodge Caravan Sputtering. Code says EGR Valve. Would an EGR valve cause the van to sputter and run rough?


Absolutely. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration.

The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.

96 Ford Windstar runs rough, check engine light on


Sounds like you have some EGR ports clogged up, remove the intake and look at the egr ports all but
#1 cyl port will probably be at least partially clogged, hope this helps
