Let me start by saying that this car is pissing me offffff!

I"ve had this P0505 for ever, which is the famous IACV.. So i replaced brand new IACV, checkd resistance, cleared the SES, nothing same code, and low idle sometimes stalling...

Now to say i've been reading around the org, and i seen a couple posts which indicate that my ECU is GONE!!!

is that correct? and if so, where can i get one? can i purchase one from a junk yard?

Thanks

 

what year max you have? I had that code on my 99 for a long time, replaced new part and code still kept coming back, tested each wires and i guess by moving wires around it got a good signal and eventually went away. I didn't have any broken wires just a bag connection at one of the pins. Electrical problems are a pain to diagnose. good luck.

you can purchase a used ECU from a junk yard and swap it out if you have a 95-98 maxima, for 99 max you will have to get the key reprogrammed.

 

I forget to mention it...

2001 maxima AE 5spd w/124K

 

you will need to get the ecu reprogrammed when you swap it out. car will not start otherwise.

check your connections thoroughly.
