There is, what looks like, some type of sensor that attaches to the fuel rail. It is about 4 inches away from the firewall. I was cleaning my engine and my sleeve hit it...and of course made the top of it pop off. No...it couldn't just fall on to the ground...it vanished. There is now a 3 prong end exposed...what is this?

Damn don't you hate when that happens? I had the wire clip on the ref sensor connector do that and only found it a year later, after selling the car. The replacement wasn't available at the dealer and I had to pay 5 bucks as a favor for replacement.

if its a round connector that runs near the ref/speed sensors it doesnt do anything anyway

Porsche hates us...the engineers are passive-aggressive.

Its about 3 inches away from the o2 sensor hub...towards the passenger side. There is a clip that attaches it to the fuel rail.

I believe you'll find it's actually attached to the chain hook on the end-cap of the cam box. That is a plug for a Porsche factory diagnostic sensor.

dropped the belly pan and nothing ?

BlackOp

Thats where it lives...I have a feeling.

BlackOp

Yeah...thats it. I was just concerned by the exposed prongs.

It sounds like your talking about this:

If so -it doesn't serve much of a function... If you bend a metal coat hanger into a hook, you should be able to get it...

Can it run with the flux capacitor missing?

As long as it didn't fall into the bellhousing black hole don't worry about it...

basically it just goes to another sensor near the ref sensors- no power is hooked to this and it is just for factory use. I usually just pull that sensor and pitch it.
