Air sensor in air duct

[Atomicandy]

I will be taking the engine cover off soon.

The sensor in the air duct. Does it pull off or does it need unbolting.

If it does need unbolting do I need to take the air filter out to get to the other side of the sensor ?

Cheers

There is plug! Its hidden behind the air hose right in front of the firewall. In the near of the throttle body plugs because its on the same loom.
you can unbold the cover and slide it a bit backwards then you can see the plug.

Don't want to break it

I don't have that sensor on my '05 plate AA2 300. Could it be after-market? Where does the cable run to?

[Atomicandy]

Into the main loom. I'm guessing it's a temp sensor

Still not sure what it is but the pic suggests it's a connector that just pulls off

[Atomicandy]

It's solid. I'll unbolt it and go from there

its a clip connector.
you can also loose to upper clamp on the dryer hose. then you can press hose down on the intake manifold. now you can see the connector from point were you took the picture.

Filter in/out easy and good practice anyway. Interested to know what's on the other side

The picture looks like outdoor heat shrink tubing (thicker and with a glue on the inside). I would want to disconnect it and look at it from the inside and outside in a more convenient location before deciding whether it was actually a workable plug/socket combo.

HOWEVER... Since the nuts are on the outside (funny, the nuts can usually be found on the inside of an Atom ), I'd be worried about the inside bolts / bracket / whatever dropping off and sliding down the air hose into places where they shouldn't be*, so I'd suggest disconnecting the lower hose clamp and putting a ziplock (reclosable, in case that's a US-only brand thing) with a rubber band on both disconnected ends to keep stuff from getting in / falling out**.

* Changing the cabin heater / AC blower motor on a BMW is similar. The factory instructions say "You may find it useful to remove the head from the engine block first" and once you get to the blower, it is easy for the screws to fall down inside the blower housing, where they will get stuck in the air conditioner evaporator coil fins. You can either remove the entire dash / center console from the interior of the car to get it, or you can remove the Final Stage Resistor after removing the glove box and then fish around in the opening with a magnet-ended gizmo to get the screw out. Ask me how I know this (#1)

** Be sure to remove the plastic bag from the end(s) of the intake. Otherwise there will be a huge scary bang as (hopefully) the bag splits (as opposed to being sucked into the engine). Ask me how I know this (#2)

There you can see the plug!
