The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.

There was a loud chirping noise when the car is cold. I changed the water pump, idler pulley, belt and the sound still continued. I suspected the camshaft synchronzier and when I took it to a local mechanice he confirmed the issue. The part was changed and the sound immediately went away.It was difficult to pinpoint on my own because the sound would lessen dramatically once the car became warmer.
same noise,not fixed yet!
I have had this chirping noise for over a year on and off faint then went louder. Had breaks done over about 3 times due to misdiagnisis. Then I thought maybe barring, but mechanics had replaced bushing and tie rod ends last year and they didn't see or check bearings at that time. That noise never went away. I've been annoyed with this loud chirping noise for way too long and being sent back and forth frustrating. Now reading this I think sounds exactly like the issue. Hoping they can fix or find problem next time around. Thank you for posting these, really helps. Sincerely, Ruth Pease
me to i have it in shop now because the fuel pump went also
Car chirps when I start the car in the winter. Chirp goes away when the car is warm.
about every 6 months it will start chirping
