Can someone help me out.

This part on my car is making a faint ticking noise when the car is in idle. I just replaced my MAF which cleared my CEL code P0171 However I can't imagine this part ticking being good, even though it hasn't thrown a code yet.

Any idea what this is called ? Check valve?


Can anyone help. I would like to get the problem fixed asap.

N80 valve. Its an EVAP system cycling valve, and yes, its supposed to click.

 

It is supposed to click loudly enough to hear in the cabin of the car, also it is not a constant clicking, it kinda starts and stops as it pleases. Is that still normal?

Also I looked up n80 valve on ecs tuning and couldn't find anything, any help in means of locating one of these guys?

Thanks for everything!

 

unless you are getting a code/CEL for it, its normal.

 

Is this it? I found part number 06B-133-459-D on mine. I think it is bad. My engine has been idling hard and the check engine light has been coming on and off. I changed the in-line check valve, but I think I need to order this as well.

 

It clicks loudly, but not constantly, right?

 

Mine is not clicking constantly. I haven't heard it click recently... so may need replaced...

 

If it ain't broken, don't fix it. I think it's supposed to behave like it does.
