Hey, I am new here. I just bought a 2001 Maxima SE knowing that it needed some work. It has the p0505 code. All the research I have looked at says the IACV and the ECM are done for. I pulled the ECM and sure enough it is burnt up. So, i am looking to send it off to get it repaired. Where do you guys recommend? The two websites that I find appealing are avproecm.com and circuitboardmedics.com. avpro is $250, life time warranty and the chip they put in can tell if the IAC is overloading again, and will basically shut it down so the ecm is protected. circuitboardmedics is $200 with one year warranty. Only prob is avpro only deals with money orders, and their site isnt very professional, is it a scam?? Any way I appreciate any feedback!

 

Why don't you fix your IACV and buy new (used) ECM. My 00 ECM was dead and bought used one from ebay for 80 bucks I think.

 

IACV i will buy new, if i get a used ecm, the keys need reprogramed, and there is no nissan dealer in town, plus the $100 charge.
How do you fix the IACV?

 

Check the local locksmiths in your town. Most of them make and program car keys.

 

Both websites are legit, however I think it's overkill to replace the mosfet with avpro's custom mosfet circuit with overload protection given it took 11 freaking years for my first IACV to fail. It's not like these things pop every 2 or 3 years or something. As far as warranty, others here who have had their boards replaced will tell you that these companies will give you the run around if you ever try to make a warranty claim, so don't let their warranty give you any kind of warm fuzzies. There have also been a few folks who sent boards for repair but the boards still didn't work, and of course these companies claim they did and they must have been re-damaged, blah blah blah, so you could end up wasting a few hundred though that outcome seems fairly rare. Anyway, by far the cheapest and easiest solution is to buy an STA509A mosfet off eBay for $12 and either install it yourself if you can solder or find someone to solder it in for you (a TV repair shop for example, and they won't charge you anywhere near what these places want).
