Hello Everyone!!!!

I have a 1999 Accord LX and recently received a eror code 0505. The book tells me its a "Idle Control System Malfunction".

Can anyone tell/show me where this unit is and what does it do?? How much is the unit itself??

Thanks for all the help.

 

I have a 97 but on mine it is on top of the intake near the throttle body. If you are looking at the engine from the passenger side it is on the left at the top of the engine behind the throttle body. It is very close to the body and is round. You can take it off with 2 or 3 bolts but I understand it does have hoses underneath that have to be disconnected. Then there is a screen that is usually gunked up and needs a good cleanning to restore your idle to normal. It is on my to do list at 140,000 miles. It keeps the idle regulated I believe however the computer tries to adjust air/fuel when it it dirty to keep the idle at 800 rpm. Would not think it would ever need replacement but could need a part replaced. Cleanning is what it would need most of the time.

 

Thanks for the info TR-3.

I heard it also could just need cleaning. I'll try to take it off and figure out how to clean it.

Wish me luck.
