Question about 1989 Toyota Pickup SR5
I have a 1989 toyota pickup. The IACV screw came out. WHat can I do to fix this?
If you have the screw and the little spring around it just screw it back in. If it is lost then go to the wreckers or carby repair shop and get another screw and spring. screw it all the way in until it touches then unscrew it 2 full turns . That will get it started and then adjust in or out until the engine idles smoothly.

the MAF sensor is between the air filter and throttle body. the idle controll is at the throttle body.
Its located on the throttle body on the left side. Follow the air intake to an intake manifold which sits on top of the throttle body.

You idle air control valve should be located on the throttle body. Here is a link to a picture of it so you can see what you are looking for: http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?categoryDisplayName=Engine+Management&fromType=parts&fromString=search&parentId=cat30067¤tPage=1&filterByKeyWord=IAC&isSearchByPartNumber=false&navValue=15900207&categoryNValue=15999999&fromWhere=&itemId=prod61721&displayName=Idle+Air+Control+Valve&searchText=IAC Let me know if you have any other questions.

P0505 is correct, but replacing the IAC won't help if the PCM cannot control and/or monitor the operation
you need to measure voltage at the IAC and/or the signal return to the PCM

Yes, I just had the same problem and I cleaned it with STP throttle body and carb cleaner. Take off the air big air hose off of the throttle body. You will see a small hole on the lower right side. Put the spray nasal on your cleaner can. Stick the plastic nasal directly into the hold and spray it for about 7 seconds. Then take the nasal off of the can and stick it in the hole pushing it in and out for a few minutes. Then put nasal back on the can and spray for another 7 seconds. Now wait for 20 minutes. spray one last time for a few seconds and you are good to go. You will be shocked on how much better you echo will run. I almost spent 225.00 for a new idle control valve, man I sure am glad I did this. My car is running better now then when I first bought it. Good Luck !!
