I just picked up an 07 AP2 with 38k miles.... (CPO)

I did not notice this sound until I let my friend drive the car and rode in the passenger seat. I hear a slight ringing noise while under accelaration. It does'nt do it if the car is in neutral and I rev-it.

Thoughts? TCT (maybe)?

Is this something that Honda will warranty?

Thanks!

 

Video would definitely help here.

 

I'll try and post up a video.

It looks like it starts right around 2200-2500 RPM

 

Sound sort of like a cricket? Probably your pcv valve. Do a search there has been plenty of discussions about this

 

Hmm, interesting looks like it's a cheap fix and easy to-do.

Thanks for the input!
