Bongo Fury

I have the engine bay open up and found some sort of sensor probe by the hand brake -- it has a plastic probe pointing downwards.
I think it may be a temperature sensor for the engine bay. Can anyone advise?

It is indeed the temp sensor for the engine bay and it is responsible for controlling the scavenger fan. If you disconnect the plug, the fan should come on.

Thanks Simon - have you managed to get any impedance (disconnected) figures to check it?

No, but it may be in the workshop manual. I'll try to remember to have a look when I get home. You could probably do a basic test with a hairdryer to check it does something.

Hi
Exactly what I do...test every season to check it's working....hairdryer.
You'd actually be surprised at the actual heat needed to turn it on, but as a rule, if the engine is running at normal temperature, and you leave it on a hot day parked for around 10 minutes or so, the heat rising in the engine compartment will turn it on when you switch the ignition back on after parking , and within 1 kilometer or so in normal traffic speeds, it will go off, as the forward motion causes the underbody tray to scoop air and direct it up over the engine, cooling everything in the engine bay....
Cheers
Helen
