Hi i'm planning on removing my Tb soon to clean it i was wondering if any one here has done it befor and if you have any tips that would help me out.

I've heard things about disconnecting your negative battery cable for 20 mins and then starting the car when your finished.

If somebody could clear this up for me and share some tips that would be great.

Thanks.

 

The TPS (throttle position sensor) is attached to the back of the TB. If you can, leave it connected to the TB and just unplug it from the wiring harness. If you do need to take it off the TB completely, make sure you've got some way of checking voltage so you can make sure everything is setup properly when you put it all back together.

Clean out the inside of the TB, along with the butterfly plate. You'll also want to clean the exterior and the back of the TB. There's not really much to the TB itself, so you'll see when you take it off. You'll probabaly need an new TB gasket, so keep that in mind.

Disconnecting the negative battery cable will reset the ECU and allow it to relearn some parameters faster. It's not absolutely necessary, but from a safety standpoint, you should disconnect the neg battery cable to prevent any arcing and such while you're working on the car ... especially with this project since wiring is involved.

Good luck.

 

ahh thanks alot man that helped out alot , hey one more thing bro because i heard lots of peolple have idiling problmes when they reattach it again like the rpm meter bounces to 1300 back down to 900 is that the ECU trying to readjust it self.

Can u just give me some steps to follow befor i put on the Tb back onto the manifold , like how long do i let the car idle for when i turn on the car or, do i turn on the car then disconnect the negative battery cable for 20 mins then rettach it.



Thanks.

 

ok never mind i got it i hope this will help every one else who plans removing thier Tb and cleaning it, i found these steps on some volkswagen forum i'm pretty sure it's the same steps would apply to a honda or any other car.

I have searched and searched and have not found much on this topic so I decided to do it myself and then tell everyone about it!
First: Disconnect the Battery! I have always been one of those guys that does not disconnect the battery because i know what i am doing but in this case it is extremely important to do so in order to reset the idle position. (found that out the hard way)

Second: Disconnect air hoses and electrical components from the intake manifold (throttle body) and disconnect the air hose from the intake side as well and rotate the hose clockwise so it is out of your way. (you can completely take it off if you want, but it is not necessary)

Third: Remove the 4 hex bolts and the throttle wire (it is not electrical, it is the wire that connects to the accelerator and makes you GO!) Then remove the throttle body from the intake manifold.

Fourth: Get some carb/ throttle body cleaner and a tooth brush and go to town on that dirty son of a B. You can also spray some into the intake manifold and wipe it out with a paper towell if that is gunked up too.

Fifth: Place the throttle body back onto the intake manifold and put the 4 bolts back in. Reconnect the accelerator wire (it wraps around the bottom and seat the little ball on the end in place. Reconnect the air hoses and electrical components, you are almost done!

Sixth: reconnect the battery and with the hood open turn the ignition on to run position (do not start the engine yet) and you will hear a buzzing noise comming from the throttle body. It is aligning itself.

Seventh: Turn the ignition off and then start your car. if your idle is still messed up you should turn your car back off and disconnect the battery again and do step six over
