I cleaned my throttle body and couple of days later my SES came on. I found a loose hose and reset the light. Then it came on a few days later and I took it to Nissan and they said the automatic throttle adjuster went out and they will replace it under warranty. Did cleaning my throttle body cause this to happen.

 

same thing happen this side but gettin a whole new tb

 

is your car idleing high?

 

my car runs like a dream since I cleaned the TB....no problems.

 

no my idle is ok. the car actually runs better. the stupid ses is on though

 

I wonder if 2002-2003 models should even have this done... you'll notice irish44j has a 2000, I do too, our throttle bodies are mechanically controlled (not drive-by-wire)
Maybe the 2k2-2k3 electronic throttle bodies should shy away from performing this procedure?

 

I am wondering the same thing or is there a cleaner that is safe for the electronic ones.

 

I cleaned mine (2003) no problems yet, also not much improvement, but it was dirty.

 

I have cleaned mine a few times already, no problems at all. Once I turned on the car and disconnect the hoses and poor in the FIC and the light came on, but went off after a few days. Ohh by the way the SES light is on again.... I just don't care anymore about it..

 

did u open the butterfly manually with your hands ? i think that what causes the problem

 

I did open it manually. I actually took off the whole assembly and unplugged it and cleaned both sides and down into the intake manifold with a screwdiver with a cloth on the end.

 

dam i wana clean my throttle body but if my SES Light is gana come on them do i take it to a shop or do i try cleaning it my self ?
If i do it my self what do i need what it the best cleaner and how EZ is it to do?

 

My SES light came on during the cleaning of my throttle body. That was only because BGK recommends starting the car and spraying shots of cleaner into the throttle body with the air intake off. With this said there was no air flow accross the MAF sensor so the SES light came on. I unplugged the negative terminal on the battery for a few hours and knock on wood the SES light went off. By the way I have a 2000.

 

this only applies to the 5.5 gen maxes. If you move the butterfly around it will cause the SES. You need to perform an Idle Air Volume Learn Procedure, which will relearn the position of the butterfly.

 

well if thats true the dealer is rapin themselves since they gave me a complete new throttle body

 

I too cleaned it and my car has not been right since. The SES light is on, idles 300 RPM higher than before, and while coming to a stop it's downshifts are jerky and the RPM bounces around. I did open and close the plate by hand while cleaning and I did spray cleaner all inside, but I did not have the car running while I did it.

I took it to the dealer and I can't remember what the code was or what it meant but they said that they checked everything and found nothing wrong so they ordered a new ECU. They acted confused about what the code meant and just came to the conclusion that the ECU was bad. I did not tell them that I cleaned the TB and that this all happened because of that.

So they are going to replace the ECU for nothing because I know that's not it.

 

Do you know how to do this, and if so can you tell us? Is this something that can be done without the dealer?

Well, I just got home from the dealer. They replaced the computer and the car runs better than it did new. I have NO IDEA how cleaning the TB could damage the ECU but a new one solved the problem. I just don't understand. I reset the ECU and everything was the same. The SES light came on in the same amount of time with the same mystery code. There was nothing wrong with the ECU before I cleaned the TB.

I also took the MAF out and wiped it with a alcohol Q-tip like some one said. I bent that little wire on it and thought I broke it. I carefully bent it back and I didn't get any SES light so I guess it's fine. You think I am going to have any problems later on since I bent it. I knew it was fragile but damn.

Off topic - I also had my sub woofer replaced and I saw the invoice that came with it. It said CLARION on the header. I knew that the HU was Clarion but now I see that the speakers are too. So where does Bose come into the scene?

 

seems like all the 5.5gens are having problems with this...i got my friend to hold my butterfly open while i cleaned it...unfortunately i didnt have enough time to take the entire throttle body out and get some of the intake manifold which i wish i did cuz the rag came out filthy...goodness...afterwards the car feels soooo smooth...a must do for people with miles on their cars.

 

I had experience also with this as a 5.5. I got the SES for the longest time and then I went back to stock intake for about a month and the SES light went away.

Probibly dosent too much sense but I wont be cleaning the throttle body again, unless I really really have too.

 

I've had quite a few Nissans including a '99 Max SE and my current 2k3 Max SE. I always clean the throttle body before doing an oil change and have never had the SES light come on afterwards. These cars have stock intakes and I perform the throttle body cleaning with the engine off.

 

dammit, i feel so not-alone now!

haha i thought i was the only one. I thought i may have bent my throttle plate because i held it open with a screwdriver wrapped in a rag. I had suspected i just needed to perform the idle position learning procedure but it seemed a bit too simple. I was checking everything physically first. I'll try the procedure when i get my car back from energy.

P507 Idle Control Valve RPM high

my car runs fine, it just idles at about 1000rpm warmed up.

haha i was too lazy to post b4 so thanks to the thread starter.

 

I have a 2k and I had the same thing happening. Initially, it idled like complete crap afterwards would idle between 1k and 3k!!! The Civic rice boys thought I wanted race them.

I reset the ecu, the light came back on and the same thing kept happening. After a few days it stopped, and the idle is stable at 1k when it used to idle at 500-600 warm.

I read the code and it reports the idle air valve.

A new idle air valve costs $175 and it's just not worth it to me to fix it when it is now idling stable at 900-1k.

 

I would like to add that despite the higher idling, I get seem to get 1-2 more MPG and slightly better throttle response.

 

i attributed the extra throtlle response to the TB cleaning..

 

P0507 Thats the same code I had. It eventually just went away durring a really long drive (300+ miles). and the SES light just turned off.

 

I just got my car back from the dealer and the ticket says "found electronic throttle actuator to have internal failure, replace throttle chamber /ETA performed idle air volume relearn and lear codes" then it lists part chamber assembly and throttle gasket. All under warranty
I hope this is something unrelated but it sounds by all the post in this thread that it is not. Which sucks because my car ran smoother and had better throttle responce and even pulled harder after i cleaned the TB. Guess we will have to find a new way to clean it

 

Can any one make the how-to clean the tb.I want to do this ,but how.
Thanks

 

well i knew they was goin to give u a new tb since they doin that for me , i don't think they did the air volume relearn on mines but anyway no need for u to be re un happy jus look at it this way u gettin a complete fresh and clean tb so might even be more responsive then the one u cleaned.

Does any one have any tips on cleaning the intake manifold?
