Honda Civic FD1 Maintainance (DIY)

[TG10E24]

Honda Civic FD1 - R18A Throttle Body cleaning after ~ 50,000Km.

Symptoms: Vibration when the A/C is cycling ON
What happened: There was a very little amount of carbon build up on the throttle body and the RPM was dropped by ~200 due to the reduced gap between the throttle body and the plate. It was enough to make the vibration when the A/C compressor is adding some load to the engine. It got recovered within a second; however I felt that so badly LOL

* Need to remove the air box completely
** Don't force open the throttle plate (It will damage the throttle body, strip gears and mess your idling)

*** To open the throttle plate for cleaning, turn the ignition ON and ask some one to press the accelerator or use a weight.

**** Use throttle body cleaner, contact cleaner or carb cleaner.

***** Don't forget to hook the MAF sensor before turn on the ignition otherwise it will log 2 errors (you can clear them if you have a scanner).

****** This method is without disconnecting the battery. No need to re learn the idle after cleaning.

Before:

 

 

 

After:

 

Cleaned everything and also cleaned the engine + transmission because it's hard to reach this area after assembling the air box
 

Vibration during A/C cycling ON has disappeared and the RPM is stable at ~800

P, N + A/C ON
 

D, R + A/C ON

Honda - Solution for chattering noise under the dash.

If you are hearing some kind of a chattering noise from under the dashboard, this might be for you (Video 1 - after 11 seconds).

There are multiple actuators in the air conditioning system; however in my case, it was the actuator used to mix cold and hot air.

As you can see, the actuator is having hard time to recognize its position (Video 2).

Solution is to clean all the brushes with alcohol and carefully bend them up (slightly) to make a good contact with the carbon trace (resistor).

Note: Grease you see here is dielectric grease. Don't clean them if you don't have dielectric grease with you.

Hope this saves you time and money.

(PS: If it's still giving troubles, most probably your carbon traces are out of the shape and need a replacement )

Tried this and it worked for me too. My FD4 was vibrated when the AC engaged. Now it's gone. Thanks for the thread buddy.
