Hey guys,

So i got the check engine light on and the code came up P0505 which was the idle control system, so i got it replaced and then no problems for about 2 months, but then i recently the eng light came back on saying the same code.

So it is a faulty part, or do i need to replace the ECU, or anything else?

Thanks in advance!

 

Are you having any problems with the idle? I had the p0505 recently. Check out this thread: http://forums.maxima.org/5th-generat...-stalling.html I ended up replacing the IACV and ECM.

 

my car has 271,000km on it, its wierd those things that happened to you guys is not happening to me like the stalling (knock on wood)

 

Seems like this issue is becoming more common as we start to see our 5th gens age....

I have this issue as well and I would start with replacing the IACV and go from there.

 

i did replace the IACV, the engine light is styll on.
next im thinking ECU?

 

Did you get the code re-checked? Same one, different?

 

yeah im gunna get it rechecked tomorrow by my mechanic, but today the light came off again lol, and in the morning it also stalls sumtimes on days like today (rainy and muggy outside),
and i replaced the starter about 8months ago.

 

You can get it checked for free at autozone, pep boys, etc. Hopefully you're not paying your mechanic to check a code. Have you tried the Idle Air Relearn? If it won't take the relearn, then your ECM is probably fried as well.

 

i live in ottawa canada no autozone
but my mechanic usually doesnt charge me to check it,
especially if it comes right back on.
I havent tried the idle air relearn but i will ask him for sure, and try that!
hopefully ecm is styll good

 

so i went to my mechanic today and the engine light wasnt one,
he wasnt sure what the relearn was,
how do u perform it?
thanks
