Sorry to bring back a one year old thread but I had a few questions and yes I have been using the advaned search correctly.

I have the the exact same codes as ManFriday, the p0171 and p0410

I have a amazing rev and acceleration in first gear and all the other gears are just sluggish and wont rev fast even with stepping on it

Somebody please help me out, Ill try to diagnose some more

Carbon Fibr

P0410 - AIR system problem
P0171 - System too lean

Cat is probably plugged.

0171 problem solved.

0410 = clean SSV & check air pump lines&connections

You sir, are the epitome of awesomeness.

Will do this weekend. Although I know the cat wasn't the problem because I took it off to put in a midpipe and the honeycombs were crystal clear.

And noticed youre a fellow Ducati rider! Ducatis ftw!

Wait a minute....

About a couple months ago I had the stealership steal $2300 to replace my OMP due to my RX8 being completely in limp mode, worse than what I am experiencing now. Could the loss of power be due to their programming of the OMP? At least that's what I'm thinking at the moment.

Carbon Fibr

Yeah Ducati's are the cats ***~ cant wait on summer. Panigale here I come.


as for power loss.
Idunno.
If your slugish in all other gears accept first. Id say its a computer issue.
But than again if your only seing a slight power loss id say update your ignition system, worked on my car when I noticed a sputter around 6k rpm.
Proper air, proper fuel, proper spark = happy

Sensors too is what you're going to probably to have to check.
Id say MAF sensor & O2 sensors. Just do some cleaning.
i could be wrong though.
Read around. Use google to search different key words always adding in rx8Club, theres a lot on this topic. See what people have tried and see what has worked.

Aight sweet man. Hopefully its just the computer problem and I can just take it back to the dealership so they can correct their mistake

hey - first post and its a stupid one/tread revival,,,,,,
having the P0410 issue, with my code reader air system ect... located the air pump un-plugged it re-plugged it in lol it pumps and runs but its still throwing that code :/
does any one have a definite answer to p0410 because in not keen on replacing a running pump.




my background is more hands on, I've pulled rebuilt and reinstalled a 05 Mazda 6 2.3l gt 5speed,
iv'e built a '95 240sx with kade-T and a just bought an 04 rx8 6spd not running, got it running and ordered my coilovers, exhaust piping(going to fab up my own 3") installed a run/turbo timer, installed a cai and intend to relocate the battery and fuse boxes to the rear.

I'm not a fan of anyone touching my cars other than me, especially the dealer

Hey guys, sorry for the late post but I am in desperate need of help.
2004 mazda rx8
76000 miles.

She runs normally besides the check engine light.

I have the P0410 code, I checked the vacuum solenoid, air pump, and control valve and they are all working properly. Went to the stealership who wanted 600 dollars to clean out the manifold which may not even be the problem which is something I know I could do but it is going to be a bitch, but I have been reading through a lot of posts and noticed it obviously is clogged somewhere. My question is to you: What should I try next? Should I check the Cat? Should I use sea foam? What should I do first!?

anyone have part numbers for the solenoid and pump? car runs great in every gear. we dont hear the pump on start up, so we're thinking it's either the pump or solenoid

have emissions coming up..... otherwise we wouldnt be worrying about it. catless mid, so it's not the cat

Hey guys, as old as this thread is, it's still good that it's here, cause I got problems myself...

So I have 2 CEL codes, the P2259 fault code, and a pending P0410 code. The 2259 says Secondary Air Injection System Control B Circuit Low, and the 0410 says Seconday Air Injection System. I figured the 2259 was the AIR Solenoid, the one with the blue plug in the rear of the intake manifold, and the 0410 was the air pump itself. The pump was making funny noises, sometimes it would sound as if it was on the verge of running, but was barely working, so I just replaced it. I cleaned the contact to the solenoid (to try and avoid a longer process), and the codes are back. I don't know why I get a pump CEL because I replaced the pump and is working properly... help...?

I had the same exact issue as you regarding both codes plus a P0661 code. I replaced all 3 solenoids which eliminated all of the codes, for a time being at least.

Initially I just replaced the air pump which I knew was shot and with the codes still not remedied, I committed a free Sunday afternoon to replacing all three solenoids (everyone needs to take their upper intake manifold off once to experience the frustration of removing hidden bolts in spaces only meant for toddlers to service:cussin g:). After clearing the codes and a 15 minute test drive, I was code free... or so I thought.

After a 3rd or forth startup, the P0410 code would re-appeared. The only item I did not replace from the EGR system was the check valve. I'm hoping this will solve my P0410 issue so I can finally get my vehicle inspected.

Eirulisse

Ok, so as I mentioned before, I replaced the airpump and my codes were back. I was able to get some time and get stuff sorted out, and I changed the AIR solenoid without taking out the UIM or braking the little bracket small hands ftw! :D and now both codes are gone and I passed emissions. I wasn't able to check the valve, but it seemed ok. Now that the valve actually opens, the air pump is more silent as well.

It was disconnected and that's what was throwing the code...I think. I've got one more cold start to verify.

Is there any benefit to replacing my air solenoid and purge valve solenoid other than emissions? Will it help with mpg or something (i get from 12-14 city and 15-18 highway)? I have CEL codes P2259 and P0443. I have another code that I don't remember what it was, but after doing some research on the forums, it's related to the purge valve also. My cat is gutted so emissions is not something I'm worried about unless it will reduce the amount of fumes from my exhaust even a little. Riding with the windows down is just not possible unless I want to completely smell like exhaust after about 5 mins. Otherwise the car runs fine. Idle fluctuates sometimes between 1k and 800. But only for like a second then it stays around 8-900. It will go up to 1k and stay for a second and then go back down. It might do it 2 or 3 times sitting at a red light. Sometimes it doesn't do it at all.

That code show up on mine and my car run rough I can't figure out what's wrong with it .. Can someone help me?

rotaryifidel

I am having the same issues and also have the following codes.P096/P0037/P096/P0410/P0031/P2259/P0661/P0443/P0172... the car will not start up,all coils and wires are good but replaced the cat on my 2005 8.
Any help would be appreciated.

I am slightly new to the forums but ive been looking around trying to find a spot to post my question and this seems like the spot if its not sorry! I have had my engine light on for a year now i have a 04 rx8 its the code 90410 Secondary air flow pump seized and fuse blown. I understand where it is under the hood and what it does for the car my questions are should i try to fix the one i have if that is possible or try to but a used one online for around "150$"? This is causing me alot of issues because i am trying to sell or trade in this car and the fix for this from dealers is almost 1200 dollars and if can do it for under 200 it will up my trade in by that much so any help is greatly appreciated and welcomed. Thank you for your time!

You can either send your ecu to someone that can delete the code for you ... pm me for details on who can do this . Or , you can just get another pump .... if you ask on here someone will have one for peanuts . I've got 2-3 of them in my parts bin ..... but shipping from NZ would kill that idea.

I’m just giving my experience from this P0410 code, in hope to saving someone money. Before buying any new pump or parts make sure you properly diagnose this code. There are a lot of avenues for this code dealing with the secondary air pump. My first task was taking my air pump apart, I live in NY and the winters are cold. My car has 100k on it 75 on the motor after recall.

I took the pump apart and I found that the nut holding the fan blade onto the motor had come off. I could see the nut on the bottom vent side at the bottom of the motor. I used a Dremel and made a large enough hole to pull it out and reassembled the pump. Pump was fixed, now I checked my fuse for it and replaced the 60amp yellow fuse as it was blown.

i had cleared the code and the P0410 continued to show so now at this point I had been stuck for finding anymore diagnosis on our forum. I did find suggestions on parts but no maintenance or cleaning of the egr valve located directly across from the air pump. This is bound to the air pump with a bigger hose shaped like a “U”.

I started to search the P0410 code through google and found a few videos on cleaning the egr or check valves linked to the secondary air pumps. Please note that your air pump may be noticeably louder at start up due to a clogged or dirty egr/check valve. I used 10mm wrench for the two bolts (upside down) under valve and disconnected the “u” shape hose along with the small hose at the back of the Valve. As I removed the valve I noticed the pipe leading to exhaust manifold and the bottom side of the valve were both clogged with residue and gunk. There is also a metal gasket between the two that I had to clean.

I used brake parts cleaner and flushed the valve out from the bottom side twice. Then I filled it with brake cleaner and let it sit for about half hour. Flushed it two more times and cleaned out with a rag and small screw driver (carefully) inside. Blew it out with air and reattached everything to the car. This morning it was 8 degrees, I started the car and it was super quiet compared to before. More importantly no P0410 code and I didn’t have to buy a single part.

alexg231

so it starts up when the engine is stone cold for like 2 minutes and then shuts off?

Monstermills

Yeah like he said it’s a circular box on the passenger side, it turns on when engine is cold and sounds like a vacuum. You can pop the hose off leading to the exhaust and check for air coming out too. They fail and are the major culprit. Mine actually went bad shortly after I cleaned my egr. I found one on eBay for around $60.

If you are running catless, there's no point to the 2nd air pump.
