So I've had this whistling/whine noise coming from around the driver's side headlight for about a week now. the sound first started on a cold morning and stops every time i rev the engine but as the video shows it comes back up again. at times it smells like something is burning.

i currently have a CEL for the TPS which i would think has nothing to do with this sound. and i know i need a tct

the air pump is right there and engages on cold start up only. The likely source. They do fail after a while, or something could be disconnected.

 

so you think it's the air pump? because even when my engine is fully warm, the sound continues. every now and then it will stfu.

 

Yeah it kinda sounds like your airpump might be going bad. Mine started turning on and off randomly then blew the fuse. I had to buy a new one from here. I had the CEL for it though, it was the P0410 code if I remember right. Man you must have bad luck! I just sold you that knock sensor you had a CEL for!

 

LOL! Yeah I know, that knock sensor was my own fault when I replaced the clutch. I replaced the sensor, had the pleasure of not seeing that CEL for about a week and bam! Got another CEL. I'm heading to Autozone, maybe I do have the code.

 

Wow sorry to hear man! Yeah pull the codes and come back and let us know whats up.

 

wow your engine is really chatty. that TCT sounds really bad. have you checked the oil and made sure it's at the level it should be? my TCT is a lil noisy once the oil level is low. i replaced it last summer.

 

trust me, i check my oil weekly as i'm running mobil 1. AP1's and Mobil one =

 

yeah my engine starts to make noise around 3k miles. plus i'm anal about changing my oil at 3k miles

 

Doesn't sound like a bad tensioner to me.
