HELP!!! IAC replacement troubles - 6G Celicas Forums

Topic #50390 10 posts Started by axelrduvirage
my car is a USDM from the BOSTON area. i bought it a few years ago from a reputable used car dealer here in Nova Scotia. i am having trouble determining if my car is CALI spec or just pain ol' USDM. i need to replace the Idle Air Control (IAC) valve since i am having startup and idling issues. i called the local TOYOTA parts counter and after spending 20 minutes on the phone and giving him my full VIN, the "specialist" could not commit to placing the order since he wasn't sure the car is CALI or USDM. i found the TOYOTA part number on the IAC and he told me it didn't make sense since that was a CALI SPEC part number on a non-CALI car. he also suggested that it was replaced with the wrong part-- but there is a yellow lacquer mark across the top of one of the mounting screws (looks like a manufacturer's tamper seal). this leads me to believe that it is the original. if anyone can tell me how to confirm my engine is CALI SPEC i would appreciate it greatly. i can then get on with the diagnostics and repairs. if this helps, here are a few TOYOTA part numbers from the EGR/VAC "plumbing":



1999 2.2l 5sfe automatic



IAC 2270-74291

EGR 25620-74310

EVM (modulator) 25870-74090

MAP sensor 89420-20300





thanks

hey Lew,

yeah...they want something like $280CDN for the CALI-spec and $235CDN for the non-CALI. i will try the carb cleaner in the lines trick...it sounds like it could clear things up. i found a really good write-up on celicatech on how-to. if you have a moment can you check your engine bay and see if the numbres i posted are the same on your car. it would definately let me know if it is indeed CALI-spec.


appreciatively

i originally thought i was gonna have to replace mine as well, but i was wrong. i just took off the 2 screws and the iac block. then i wiggled the valve a lil till it was free, then sprayed it with brake part cleaner. i kept wiggling it while i was doin this as well for about 1-2 mins. just to make shure. then i let it dry, and i put everything back together.

You say you don't understand how we go dumb, but have you ever been where i'm from?-=-] Livin it in tha bay's a lil different [-=-
i have 2 available if you need one
yeah. it does not need to be replaced but just cleaned out more than likely. mine needed cleaned too.

anyway, to tell if your car is CALI-spec or not. look on the the underhood emissions label. it'll either say something like "california emissions" or "federal emissions" or something along those lines.

going to clean out the IAC tomorrow if i get the chance. thanks for the tip. funny thing about the label under the hood...it's not the original. it's actually for the 7afe, which i know mine DOES NOT have.
well, you should be able to call a dealer, tell them your VIN number, and they could tell you which it is.

quoting myself here :"...after spending 20 minutes on the phone and giving him my full VIN, the "specialist" could not commit to placing the order since he wasn't sure the car is CALI or USDM..."

That's normal.

The VIN brings up alot, but there are still things it won't bring up.

We always have to check when we get parts.

Just like someone already said, check the emissions sticker under the hood.

It will either say Meets Requirements of California Emissions or M R o Federal Emissions.
