P1404

Awesome, I have another CEL; p1404

I know what this is, EGR Valve Stuck Closed. I just have one question about this. Is the valve the pintle? If not, what is the valve?


marc

I hate my CEL.

went to napa to get some deepcreep. Upon starting my Rodeo after my purchase, the CEL is off, which is good I guess, but still. I am at my parents house (my tools are here) because I am going to clean it anyway. I have it apart, the pintle is free and there doesn't seem to be much build up. The end by the throttle doesn't seem clogged up either. In fact, I just cleaned the EGR less than two months ago.

I hope this doesn't mean that I need a new EGR. I have seen my CEL too much in the past five months. It was just yesterday that I was thinking how nice it was to have it off.


marc

wait and see. It could be the circuit board in the EGR is finally buying the farm.

Great, there was one on ebay not too long ago that was cheap. I almost bid on it. I wish I did.

I just got home after a thorough cleaning and the CEL is still off, so that's good. I'll have to keep an eye out for one on ebay. If anyone sees one, post it in here.

I keep getting this code to. The Isuzu place cleaned my egr ports and installed a new egr. 2 days later the code came back up. I took it back and they said it may still be clogged up and they would take it apart and fix it for 800.00 more dollars.
The next weekend we took it apart and cleaned it from both ends running a wire hanger through both sides and spraying a whole bottle of intake cleaner. It is not clogged and the pintle on the new egr is moving just fine. I am still getting that code and p0402, flow excessive. I am thinking it is something else at this point. Maybe img. Don't know how common that is in the 4 cyl.
If I were you I would rule out everything before replacing the egr.

yea, I'm not going to replace the EGR. So far, it hasn't come back on, but I'll have to monitor it for a while. When it popped on, it was only on for a short time. I cleaned it and used a wire hanger as well. The cleaner was flowing pretty freely, so hopefully it is cleaned out. I may clean it again soon.

marc

It's back on, with a friend.

P1404 AND P0405

What does p0405-EGR Sensor Circuit Low mean? Is it safe to say I need a new EGR valve? This is agrevating. I have no clue what this new cade is trying to tell me.

marc

It sounds like the ECM isn't getting the electrical feedback it needs to see from the EGR valve. Sounds like your valve has the broken/melted path on the internal circuit board.:banghead:

Joel

this is rediculous, all of these CEL's are starting to irk me. A new EGR valve is not going to be cheap. If anybody sees one for a great deal, let me know.

I just put $50 in the tank.


I have had serious thoughts of putting my Rodeo in the classifieds. The only major thing stopping me is the idea that it will not sell. I love this ride, but a vehicle with only 83k should not have the CEL come on all the time.

Nice thing about this listing is it lists the GM part # and the isuzu part #. Maybe this will give better search results.

Thanks for the link joel, I saw that earlier, but I'd love to see one even cheaper (I'm a dreamer). Probably not going to happen, but I'll look. It's probably not a great ideas to drive around with a busted EGR system.


marc

Can't remember if you done this or not, but before you even think about replacing that EGR, make sure to completely clean out your throttle body and the air intake tubing, along with your pcv and idle lines.

Doing this worked wonders in my Rodeo that had one of your same codes for over 5 mnths; haven't seen any in regards to the *you know what* light since.

If nothing else you can always hit the local salvage yard for one off a low miles mid-late 90's GM. Looks like most if not all GMs of that time used the same EGR.

Check out http://forum.planetisuzoo.com/viewtopic.php?t=6869

I wonder what the difference really is between all these ac delco egr valves that look identical but with different numbers.

Here is one for a saturn 4cyl

They look just like the one on my v6 rodeo.

I haven't been able to get on this site in a couple days, I was feenin. It's still going slow though.

Anyway. I took the EGR off again today and the pintle moves fine. I'm guessing it is bad. This Rodeo has been demanding a lot of my attention lately, it's driving me crazy. I am checking some junkyards out online, I see one for $50 with a six month warranty. Not bad.

I was under my Rodeo today checking the transfer case and rear diff to make sure the level was correct since I changed them out a few weeks ago. My rear diff where it meets the driveshaft is wet with fluid. There must be a bad seal there. Some oil on the gas tank too, right at the corner by the rear diff/driveshaft. I'm going to keep an eye on the diff fluid level because I am sick of spending money on this thing.

Is this an expensive fix? Probably is knowing my luck.

marc

I hear ya, I was finally able to clear and fix up the very minor leak I had at the transmission shifter on the Rodeo, double checking it's fluid level at the same time.

Then I figured I'd pop under my automatic diesel to check it's condition/level as well - and, guess what, have a leak at the area where the driveshaft enters the transmission! ARGHGHG!

Just can't win - It's always something. Good thing is, the diesel's still covered under extended warranty, only has 80k miles.

Oh, and the powersteering pump on my '85 Toyota p/up's about to bite the dust - drips on the driveway are slowly getting bigger and bigger. And besides that, there's another coolant hose leaking on it somewhere :banghead:

It's funny I ALWAYS hated it when someone would visit and their car would leave drips in my driveway, big major irritation to me, just doesn't look good. I'm discovering little by little as time goes on, that it's my own DD's causing the stains now.

No oil leakers, yet, though, just seems the diesel has the red plague. :uhoh:

Last time I looked at mine it was leaking a bit from the input seal, axle seals, and cover. I still havent check my breather to see if its clogged and causing it to pressurize. I will be checking it soon though when I change fluid again after being underwater.

One of my coworkers was nice enough to point out the fresh oil under the front of mine a couple weeks ago. Now I get to track down and fix a leak on the engine. I've never had a vehicle that leaked before.

I cleaned my breather last fall because it was rusted up. I checked again and it was closed up again so I ordered a new one from St. Charles. It was less than $5. Definately worth it.

I think I found an EGR from a junkyard for $50. I'm about to order it.

Well, I was about to order an EGR from a junkyard today and the CEL went off, so that's good. Hopefully the thing stays off.

If you know someone with a Tech II or Waekon EGR tester, you can have the valve checked rather than replace it on a hunch. You can command the EGR open and watch it to see if it moves of not. There is no other easy way to check pintle position feedback from the EGR valve to the PCM.

The circuit board and wiper contact points internal to the EGR valve get dirty and/or burnt over time . IIRC, the post I saw on disemboweling the valve and repairing the 'paths' on the circuit board (with solder or solder pen) was on planetisuzu.

Joel

that procedure looks a bit out of my league. The CEL is still off, so hopefully it stays that way. If not, I'll order from a junk yard. I may try the procedure after I get a new one.

stupid CEL, GRRRRR.

I'm ready to admit it will not fix itself. I'll order the new EGR tomorrow.

Bowtie, I should go get it checked, but for the cost of the diagnostics, I can get a used EGR. I'm hoping this will take care of it.


I keep looking at mazda 3's. I like them, just don't want to spend the money.

Yup the 3's are nice. My wife drives one. 30-35 MPG, so it is our road trip (or any trip we are both in the car) car.

https://mywebspace.wisc.edu/rendres/web/garage/mazda.jpg

Those are really nice looking cars. I think the ford fusion looks cool too. I do miss the ~11gal fillups of my 2001 nissan sentra.:banghead: Just not enough room for us. The only thing I hated about the small cars we owned was the feeling of sitting on the ground. Never liked falling into them and then hauling your arse out.:rolleyes: $3/gal+ we'll have to learn to like it!

Joel

I'm starting to see more and more of those M3, as well as the M6's - I like both of them.

What's the set-up of the engine? And is it an easy one for maintenance, or does it require a lot of maintenance between 40-100k miles??

Well the good thing is that it doesn't have a timing belt, but has a timing chain.

The one goofy thing is the fuel filter is in the tank! There is no recomened interval for changing it.

As for the setup, it has a 160 hp and torque .... not sure. We have 5 speed so it is pretty zippy. Our previous car was a 1992 Prelude Si (non-vortec, 93 was the first year of the vortex), and I think it had a bit more get up and go to her (also rated at 160hp).

..The one goofy thing is the fuel filter is in the tank! There is no recomened interval for changing it..

Yeah, you see this more and more now. Our TB has the 'in-tank' filter as well. They are usually a big sock on the fuel pump p/up. Not much of a chance of them plugging which is nice. You swap them out when you change the pump (hopefully not before!). Our 2001 sentra had the sock.

Joel

I heard the 3 has an odd type of oil filter. It is not the simple screw on type.

I am going to inquire about a lease, probably not going to do it, I still like the Rodeo, but I'll be honest, gas is a factor now.

The CEL has gone back off. I'm still going to check out the J/Y.

Yes, a bunch of vehicles use a drop in oil filter now. It's basically a plastic cannister with a threaded lid. Un-screw the cap, pull out the old & drop in a new oil filter element. Sealed trannys, drop in oil filters, maint free everything..:uhoh:

Joel

I couldnt buy a mazda, too many ford parts :lol:

The 6 is built on the ford fusion platform and the 3 is built on the ford fungus platform. The good part though is they arent just rebadged fords, they have some mazda parts and styling. I do like the looks of the both the 3 and 6 though.

BTW, I would take an RX-8 if someone happened to give me one for my bday next month :wink:

I went to the junkyard today and of course there were no Rodeos in there. I saw some EGR's from Saturns and some other GM vehicles. They did look the same. I am going to go back and give it a try I think. The Saturn was a 97 and there was a Grand Am(?) that was a 96. I may take the one out of the Saturn, it looked better.


marc

The one I grabbed out of the Grand Am seems to be working fine. So far, no CEL.

That's good info Marc! I knew I'd seen other GM vehicles with the same looking EGR valve. Do u remember what year/engine that GA had?

Not sure about the year, maybe a '96. There was a '97 Saturn that had a similar looking EGR in it, but it was harder to get at. There was a thread over on Planetisuzu (in Gizmo's post there is a link) that mentioned the interchangeability.

The engine I got it from was one of those 3800 V6's I believe.

marc

Hope it stays off for you now. Glad the GM part has worked, now thats 2 accounts of it working.

yea, it's off, so that's good. I did notice that the numbers on the tops of the EGR's are different, plus, they are different part numbers to order online. With that said, they look identicle except the connector is on the opposite side. The connector is identicle though,, and it does plug in fine. I would like to think that if it didn't work the CEL would come on. As far as it fitting, it drops right on perfect.

marc

I just pulled, and then erased, this code, P1404, which is supposed to indicate EGR issues.

Idle was very rough at times and eventually I got the CEL.

I disconnected the battery (which is key), and then disconnected and removed my Idle Air Control Motor (which is very simple).

The pintle and the port look clean.

I reinstalled the IACM, connected the battery, started it up, and drove. Runs great. Very smooth.

The CEL has not come on again yet.

Any time the idle gets rough, which has happened quite a few times in the 14 years I've had this car (currently at 254,600 miles), I pull and/or replace the IACM.

The key is to disconnect the battery, since if you replace the IACM without disconnecting the battery, the engine will run extremely rough, and could possibly damage it (?).

Once the battery is disconnected and then reconnected, the system calculates and sets the required parameters automatically.
