I have a 1997 Honda Passport 3. 2 engine with EGR valve problem -code for insufficient EGR flow crops up. I have checked the EGR pipes for blockage - it is very clean. I checked the EGR valve and it is clean. I then checked air intake manifold and throttle body - they were a little bit dirty-cleaned anyway. The code keeps appearing every other day or so or sometimes doesn't show up for several weeks. I even replaced EGR valve. What sensor tells computer the insufficient flow condition? I don't see any other sensors in EGR system. Kinda driving me crazy-any help out there? Car only has 77, 000 miles on it. Thanks!

Just do what the PRs do where I live, remove the converter and I shall one of those coffee can mufflers that make that buzzing sound, I guess they think it makes the car fast the louder it is, all the little Hondas nissans and Toyotas, you know the ones with mismatched paint some primer a gallon of bondo, plastic pieces falling off and some secured with duct tape, and maybe a plastic bag covering where a glass window once was.

I have a DIYer's OBD-II tool, a 99 Blue Driver. It's pretty cool for a big time amateur, but I'm thinking about going deeper. Is there a bi-directional scan tool that I might be able to find for under a zillion dollars? Used or new? I'm just starting to dig into stuff a bit deeper, but I'm totally fascinated from watching SMA and Scanner Danner. Dyin to learn this stuff. Thanks!

Most relatable thing ever. nut drops. heard it bounce around. yes, it hit the floor! I say that daily. on the good days anyway. much better than the ting, ting, ting, silence. Knowing that nut is on some frame rail, under a hose and 3 covers, never to see the light of day again without half an hour of searching.

I have the same exact vehicle and I was wondering is there anyway to just temporarily bypassed that EGR valve like maybe plugging up the two rubber hoses in the back just to see if the car runs correctly like that? because my car wont stay on while idling?

I had an 01 Sentra 1. 8 from new until three years ago. The 2nd owner is an associate and he's still driving it. On its original engine, mid 200, 000 miles. Not the fanciest car but a very good car. Responsive engine, plenty powerful for the car.

can a Technician educate me? My current understanding is that inline engines are a single bank engine, and V or boxer engines are dual bank. So how does a Nissan I4 show a bank 2? Thank you in advance for taking the time to respond.

Ever get the feeling you have to reverse engineer every freaking part on a car to understand who, what, why, and how just to fix it's failure. Crap. must purge something learned ten years ago to retain this.

That's awesome that Eric O. fixed the original EGR valve to save the woman some money. She's gonna need it when she sees that estimate for an OEM unit! OUCH! And yes it was WIlson from Tool Time!
