So i just a new engine installed by mazda this past weekend. The next day i drove it about 15 miles then turned off the car went to eat then turned it back on blam i had a cel. I took it to autozone and they gave me the code p2004. So i read around here that revving it hard would cause the valve to get unstuck. I tried it but the cel was still on. I took it to mazda this morning and they said that my intake manifold runner control solenoid was the issue. Since they used the the same solenoid from my old engine its not under the engine warranty and they want me to buy it. So my question is why is the solenoid not working when it was working on the old engine. Where can i get the solenoid thats not mazda and is it possible for me to change it myself.

 

any help would be appreciated.

 

Umm... a P2004 code is for the APV stuck open.
Unlike the SSV, VDI, and VFAD that uses a solenoid to activate an actuator, the APV uses a motor to spin the valve.
There is a positioning sensor that the PCM uses to monitor if the valve is open/closed.
A solenoid is NOT used to open this valve.

It is more than likely their fault for not assembling it completely.
Maybe they simply forgot to connect a wiring harness.

 

so why would they be telling me that i have to pay for a intake manifold runner control solenoid which is 160 bucks to get my CEL to go away? What the heck is a intake manifold runner control solenoid because i checked online and even through rx8 service manuals and couldnt find anything on it.

 

Maybe they misdiagnosed the issue
Kinda hard when a P2004 code is for the APV.

Only solenoids that actuate valves in the intake manifold is the SSV and VDI.

Maybe print out the section of the shop manual explaining P2004, take it to the dealer, and ask them to explain how they came to their conclusion.

 

Something that i noticed also was when i got the cel read by autozone they gave me a printout stating this:

P2004
variable tumble control system (vtcs) - shutter valve stuck open
probable causes
1- disconnected or damanged cavuum hose
2 - binding vtc actuator
3 - vtc solenoid malfunction

which kinda makes sense to what the tech said... i guess ill go through with it and fork over the 300 bucks, also what exactly does having the p2004 cel actually do. Ive revved the car and it doesnt seem to stumble or struggle. Ive heard that for normal driving it doesnt matter but for longer distance or if your pushing the engine hard it will effect performance. Anyone wanna shed some light on what harm does p2004 cause?

 

Those Autozone printouts is just a generic description and mostly applies to other vehicles (not rotaries).



But it's your money... do what you want with it.

 

thanks for the help, ill use this information to find out what exactly they are charging me for.

 

Don't be intimidated by people trying to scare money out of you. Sounds like Jon knows what he's talking about, but if you doubt him, ask some a few more credible people and confirm it. Don't shell out money just based on their word or judgement.

They are not infallible. Just a few weeks ago, the body shop couldn't start my car, decided the engine was flooded, and was going to hand it over to the service department. Eventually I realized they left my engine computer disconnected.

 

I sent Shijin-Kun a link to download the shop manual so he can print out the DTC section that explains P2004 in detail and take it to the dealer so they can explain how they came to their conclusion on it being a solenoid.
I asked him to keep us posted.

 

Ok so here is an update, i showed the tech the p2004 service manual printout and he insisted that it was the imrc solenoid that was causing the problem. So i asked him if i go this put on it would solve my p2004 cel and he said it would. So i just got my car back after gettign the imrc solenoid installed nad paying 380 bucks. So i drove it work everything was fine until i red lined it and bam i get the CEL again. During my lunch break i will go to the near by autozone to make sure that its the p2004 code and then i will mazda and give them a piece of my mind. Her is a quick question, since the solenoids that they made me buy did not fix my issue what can they do? will i get a refund or will they fix the problem without paying? thanks for the help guys

 

i just called them up and told them that i was still having the same issue the service rep said that he spoke with the tech who worked on my car and he said that there are 3 solenoids and they only replaced 2 of the solenoid that corresponds to the p2004 CEL. He also gave the excuse that the tech who worked on it doesnt know too much on how to troubleshoot the problem and that i would have to wait for the master tech to come back from vacation 2 weeks from now to completely troubleshoot the problem. I told him im not going to pay more for somethign that should have been fixed the first time and he said he would try to work something out.

 

best advice I can give you is to be calm and polite, tell them your concerns, and tell them exactly what you would like them to do to satisfy you. if they think you are being completely unreasonable they will give up on making things right and write you off as just a difficult customer

 

I found this http://www.finishlineperformance.com...14-07-1777.pdf my car falls under the vin number would this be whats happening to my car?

 

Good find!
I would definitely print that out and take it to the dealer!
So they replaced 2 of the 3 solenoids?
3rd one they didn't replace is probably the VFAD solenoid (its the less likely of the three).

If you're really concern, you can always talk it over with another dealer.
You are never stuck with the same dealer you purchased your car through.

 

I told them about the bulletin but they didnt pay too much mind to what i was telling them. They kept on saying that they are going to wait for the master tech to come back from vacation in 2 weeks until they do anything. The only reason i dont want to take it to another place is i dont want to pay again... im not made of money lol. The dealership is going to work something out so i dont have to pay again.

 

That's good.
Hope things work out for you.
Let us know what they discover.

 

Sounds like you are handling things correctly. Just don't give up, keep on them. You paid to rectify this code, and that's what you should get.

 

personally id be livid. What they wound up telling you was this:

You just paid an improperly trained tech $100 to improperly diagnose your car, then this improperly trained tech installed an improperly diagnosed part into your car. As expected the problem was not fixed.

You just paid almost $400 to have an idiot install parts you didnt need on your car, nevermind the amount of time to bring it in etc, and the frustration of still having the problem AND they want you to just wait 2 weeks for someone to come and look at it.

yes i'd be livid.

That's not how it works, i'd demand my money back for the diagnostic and repair, then i'd want it looked at right then. If the master tech is not there, ask them who diagnoses the rest of the cars, if that goes nowhere tell the service manager (yes talk to the service manager) you want to speak to the regional representative, if anything he will send mazda engineers to solve this problem. You mention the regional rep and i guarantee the dealer stops this game and fixes your car.

best of luck.

!

Don't you have to re-set the ECU to clear the code?

Try that since you have to wait.

 

You would think that the tech would have done that before giving the car back.
Then again, this wasn't their "master tech".

 

when they gave it to me it didnt have the cel, when i was driving on the my way to work it came on, and ill prove end up asking to get my money back and talk to the service manager tomorrow...sigh couldnt of this been solved the first time around T_T

 

with a proper tech at a good dealer? yes. Your dealer and tech? i guess not. Wish someone with a service manual who could help you was near by, id diag it for you if i was there in person.

Alright so heres an update of what has happened this morning: (its a little long lol)

I walked into the Mazda dealership and spoke with the service rep ive been talking to for this issue.

Me: Morning

(at this moment the service rep already know by name and knows why im there)

Rep: how can I help you

Me: Is there someone here who can fix the problem im having with my car because I cant wait 2 weeks for it to get fixed.

Rep: Why is your car acting weird.

Me: No but this problem should have been solved already and in 2 weeks I have a car even I have to go to and I cant have my car not being able to redline.

Rep: Ok well you can come back tomorrow and we can have the tech look at it again.

Me: I talked to another mazda tech and they told me to give the tech these paper for reference (hands over the print out of the dtc p2004 code sheet and the service bulliten)

(Rep reviews it and hands it back to me)

Rep: you can show the tech these when you bring the car tomorrow

Me: is there a reason why I cant leave it here today.

Rep: we are full and we wouldn’t be able to work on your car today/

Me: well im here now so it would save me the trip tomorrow

Rep: ok give me your keys and sign this paper

Me: is it possible to get my money for the parts and service that didn’t fix my problem?

Rep: the parts are already on your car so we cant give you your money back

Me: these parts didn’t fix my problem

Rep: we can give you your money back but you would have to pay to get the parts removed

Me: that’s unreasonable, lets contact mazda to see if they can send an engineer to actually fix my problem.

Rep: an engineer would not come out to take a look at this problem

Me: really so if I called the regional manager they wouldn’t send someone to take a look at my car

(rep begins to panic a little)

rep: let take another look at the car and see if we can find something else on it

me: im not paying for the service and part right

rep: if we have to order parts from outside then you will have to pay for that

me: No I wont….

I walk away after that and call for my ride, while im waiting for my rid I look up on my phone for the number to contact mazda. I call mazda and I asked who I could file a complaint for bad service and the phone rep asked to explain the whole situation. So I did, the phone rep said he would speak with the dealership to get the problem fixed today if possible, they will contact me later.

 

When he said you'd have to pay to have them removed you should've told him that they were paid for to be installed to fix a problem. The problem was not fixed and therefore the parts should be removed and replaced free, you should not have to pay to fix their mistake. Perhaps it's their stores policy but I'm sure mazda could find a way to assist you in at least limiting the damage to your pocket.

Other then that glad to see some of my advice has been helpful in your situation, hopefully they take your problem serious and give you the service you deserve/paid for.

Keep me updated,
Kevin.
