Wow, really? Because then that means that the camshaft sensor was replaced too because that's the part that came with the synchronizer.
This is the part that I was showed by a NAPA representative that is a camshaft sensor, so this is what I've been looking for:
THis is what I pulled out of my car thinking it was the camshaft sensor but later realized its the crankshaft sensor:
so now it appears as though the camshaft synchronizer & sensor HAVE been replaced, but the noise still persists. Could this mean that it wasn't installed correctly? I have noticed a slight improvement, but it still chirps.
Out of curiosity, do you think the crankshaft sensor could cause the chirping too?
Another issue I seem to be having now is that the check engine light is pulling through the p0171 & p0174 codes this morning.
(just for background information: for the last two month my car would have the "check engine" light soon on and off about every other week. Last month the chirping started. The last time I pulled the codes it was how I discovered this site and that it was the camshaft synchronizer. 2 weeks ago my MPG has decreased, but on my last 2 fill ups, it has gone back up to normal. So it's not consistent, just like the "check engine soon" light is not consistently on. So right now I'm only trying to focus on one thing at a time...)
Thanks a lot for you help!
