Does it do it once the car is warmed up? Could be the high pressure fuel pump. I believe Honda put out a service bulletin for that and they said it’s nothing to be concerned about. It won’t affect your cars performance or reliability but it can be annoying. You can still possibly get your HPFP replaced for free if that’s what it is. I heard mine chirp for a few weeks when I hit 12-13k miles, I’m at 20k now and I don’t hear it anymore.

^^could be the HPFP. You'll hear it under throttle while you're cruising on the highway typically. Not a big deal. Could be a belt, they're squeal/chirp. Whats the mileage on your car and when do you hear it? at idle, under throtttle, cruising, when its hot or cold?

Hi,
It does it when the car is warmed up. I can hear that noise when idle. My car started about 1 month when it hit over 7k miles. Thank you

Do you notice it at all while you're driving? or even if you rev it while sitting still? if you do and it seems to increase relative to speed it sounds like it could be a belt and/or pulley making noise.

Definitely HPFP then, I would only hear it during idle as well.

Pop your engine cover off (no tools needed, just pops right off) and to the right you’ll see the pump (approximately where I circled in yellow). It’s going to be covered in like a greyish/black foam, hold your ear near that area and you should hear the chirping coming from there.

Sorry for the confusion, when I said fuel pump, I was referring to the HPFP (high pressure fuel pump). As for getting it replaced, it’s not required since the car will run just fine with the chirp. It is an annoyance tho, so if you’re certain you want to chase it down take it to the dealer and get it replaced.
