Ok I got the check engine light for the IAC valve, (AKA sensor 0205).
I have the Haynes manual and they said i could check the resistor on it the IAC valve, and i did. this is the results i got.
Terminal 1,2=38.3
Terminal 2,3=38.3
Terminal 3,4=34.2
Terminal 4,5=34.2
Haynes manual mentions they should be around 30 ohms but they are higher so i want to be sure if that IAC valve is bad.
I really need someone to check there IAC valve terminal and tell me what reading they get. please if you can I really appreciate it.

 

FSM ('97) says to check resistance between terminal 2 and terminals 1,3 then terminal 5 and terminals 4,6. Resistance should be approx 30 ohms at 20 degrees C (or 68 degrees F). Looks like you checked between 3 and 4 which isn't needed/correct, and you left out between 5 and 6. Your values look good, though, because it varies with temp, and 30 ohms is an approximate. If that part was bad, I'd think you'd get an infinite reading or something drastically higher. You can also check the mechanical operation of it by: 1) Remove idle air adjusting assembly (IACV-AAC valve is built in). 2) leave the electrical connector plugged in. 3) turn ignition switch "on" and "off" making sure the IACV-AAC valve shaft moves freely back and forth according to ignition switch position. If negative, replace valve.
PM or email me if you need further info from a FSM.

Hope this helps.

Thanks a lot FOr your help, i am going to sleep now. i will email you tommarow. i have work in the morning.
