703

Alright so I'm back with another "what is that noise"
Car has been making this strange whirling noise for a while. At first I thought it was the Harmonic balancer so I had that replaced along with a few other things and to my surprise the noise is back. Yay...

Specs on the noise
can hear it at idle along with lower speeds
coming from passenger side
very noticeable in cabin, not so much outside with hood open

I think I captured the sound ok on video, here is the link

any input is appreciated.

Could it be your blower?

GS057

Is the AC on or off?

703

Everything is off except for the radio
car is stock other than a corsa exhaust

Knob Jockey

Maybe it's the CD Drive in your Nav.

You could try pulling some fuses.

Turned radio off and it's still making the same noise.
On my way home from work this morning, the check engine light came on as well.. go figure.

Checked for code(s)?
'Sounds' like noise may have revealed issue w/ a CEL, but all anyone can do w/o codes is guess.

G/L & please update, post WTH CEL's about.

Got the check engine light codes and they are
PO121 - throttle/pedal position sensor A circuit range/performance

PO430 - Catalyst system efficiency below threshold

With that being said I noticed the noise wasn't there today or not as prevalent. I'm not sure if it has to do with the weather (it was significantly warmer today) or what but this is exactly how it goes. It'll be there to annoy the crap to me and as soon as I take it anywhere to get looked at, it stops and people look at me like I have 3 heads trying to explain it.

TPS going bad I've heard of before, IIRC it isn't a major fix.
Don't know where to start w/ cat issue, though many members probably know what's up, hopefully will chime-in, help.

Intermittent faults are the absolute worst scenario for all but the most seasoned, experienced tech to track down, no codes a'tall worse yet.
Especially based solely on an owner's complaint/symptom, it isn't easy.

Fortunately no need to explain anything w/ those codes, anymore.
2 valid codes provides a starting point for effectively tracing issue.
Let your wrench explain the whys.

sounds like your cat is coming apart. try hitting it with a rubber mallet and see if you can hear any clunking.

In the last 10 years you haven't said much. And when you have...it is really stupid.
