Anyone hear a " hissing sound " when the car ignition is turned to the on position ?
Hi everyone
I have owned 2 SC and I notice both of the SC I have owned get a odd " hissing " sound
when the ignition is turned to the " On" position with the key located in the engine area
It will come on and then go off
Sometimes this " hissing " sound will come back on when driving and then off again
Have anyone heard this " hissing " sound when the key is turned only to the
" on " position ?
Thanks for your feedback

I can hear the noise coming from the engine compartment . It is like a fuel pump, ABS or a relay coming in and then off It is more a light low humming sound
When you turn the key to " on" and not start or cranking the car , does anyone hear any low humming coming from the engine compartment ? It is clear there is a low noise . I have one SC I sold and now another one and they both emit this same noise

Actually you can get noise from the fuel pump also amplifier fan running I believe that your abs can produce sound also actuator for air cond heating. Others may add to this thread I have not experienced this or maybe not paid attention

The low humming noise is very obvious and it will come on when you turn the key
to the " on" position without cranking the car
Sometimes it will also come on and then off when you are driving the car
Does everyone hear this low humming noise ? It happens with both of my SC
I guess it is not a big concern but it is there

I must say the above is closest to what I think it is. When you start your car, the 1st exhaust gases go to the charcoal canister, hence the need for the infamous EGR valves. You need heat to get your catalytic converter running to burn the bad gases.

Are you guys all hearing this low emitting " humming " when you turn the key to the on position ?
It will also come on in occasions and then off when driving the car
I am pretty sure this was also the noise I heard in my 04 SC with 53K As well
Before I bought my current 03
It is not a buzzing or a whining of moaning noise but a low humming
noise
Otherwise the SC has been solid all around
Just changed timing belt , pump and all belts
Cheers

This low humming noise is noticeable when you first put the key In the " on " position
Sometimes you will hear it come on and then off when driving
I am just curious is this common for the SC

How long does it last?
I turned my key on and heard the fuel pump, antenna, HVAC servomechanism adjust the air defectors inside the dash and the boot sequence in the engine compartment.
Everything was complete within 15 seconds, then silence.
If you are hearing more of a humming sound, it is most likely the fuel pump.
If you have a smart phone, use your camera and create a video, then post it to YouTube.

Hi BgW70
I will try to post it on you tube but the low humming you mention
Is usually when you put the key in the " On " position
It will sometimes stay on and when you start the car and then off
does this sound like a servo ? It is definitely coming from the engine
Area . I opened the hood and it looks like it is coming from the firewall
And the engine .
What is a boot sequence ? What is an air deflector ?
