I changed the IAC...

I changed the IAC valve and it idles fine now but the engine light comes on

Mechanic's Assistant: Has your vehicle stalled? Has anyone run a diagnostic test to pull the trouble code?

It does not stall but the trouble code shows IAC valve

Mechanic's Assistant: What is the model/year of your Infiniti?

2001

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

Yes I am. It was idling at 1200 rpm before and now it idles at 800 which is fine but the ck engine light is on

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I don't think so

Customer reply replied 4 months ago

It's a 2001 and the trouble code translated to IAC valve. It's brand new.

can you post a pic of the dash with the key signal ??

Ask Your Own Infiniti Question

sorry that was not for you

Ask Your Own Infiniti Question

it is very common for the valve to burn out the ecm I think that is the problem your having if the valve is new and you still have a problem with the code not resetting

Ask Your Own Infiniti Question

did you try to reset the code with a scan tool ??

What Customers are Saying:

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
