Where is the egr valve located on 1998 Honda Passport and how can you correct EGR flow insufficient?

Answer 1

Locate and clean the EGR valveIt is located on the left side back for the engine looking from the front. Once u find it remove the two bolts and pull upward. Remove the gasget and use Carb cleaner to remove all the carbon deposits inside the EGR valve. This worked for me and i saved 110 dollars by not replaceing it. Works just like new.

You might also want to clean out the intake port located in the throttle body. That was my problem. All I needed to do was remove the air intake cover to the throttle body and take a small bristle brush and clean out the exhaust intake. It wasn't getting efficient air intake and that is why my code kept coming up.

I just completed the full top end cleaning on a Honda 3.2 L engine. I found it to be a fairly simple task for a home mechanic. The main thing I found was a carbon blockage where the vacuum tube comes out of the back of the intake and goes to the vac solenoid on the left side fuel rail. Easy to clean. just pull the vac tube off of the fuel rail and spray carb cleaner thru to the intake. after I performed the complete upper end cleaning My engine light went out.
