Hello, and thank you for your question. Do you have a Idle Air Control Valve code?

Yea I do it's P0505Yeah it’s P0505
Automotive Expert
I hate to be the bearer of bad news. When you get this code, this requires the Ecm to be repaired and the Idle Air Control valve to be replaced. Let me explain...

What does that mean
Automotive Expert
The P0505 code is for the IAC control system. What happens is this. The IAC has [coolant](/topics-coolant-nissan/) going around the chamber to cool it. So there is a gasket for the IAC. ( Idle Air Control ). When this gasket fails, coolant seeps onto the IAC motors and shorts them out. So now when the IAC gets shorted, it also damages the ECM where it would control the IAC. So if you were to replace just the IAC, the Ecm since that circuit is damaged, will damage the new IAC. So what needs to be done to correct this, is to replace the IAC and the ECM both at the same time. Other wise you will never get a head of the issue. When you do that, you will need to reprogram all your keys for your car and have a Idle relearn performed to verify the repair. Since the Ecm is no longer available, you would need to send your Ecm out for replacement

what is the ECM
Automotive Expert
Engine Control Module. The Engine Computer

Oh okay and how much money do you think I will spend on all of this
Automotive Expert
I am going to guess between the Ecm repair and the Idle Air control valve, with parts, labor and key programming, I am going to say around 1k dollars

Damn I wish I had that type of money
Automotive Expert
Yeah.. It's a shame...This issue puts most of these cars in the junk yard. So don't even think about trying to get a used Ecm. Most likely they are bad.

Right
