what should go to this??


and where does this go?



haha i was lookin under my bay today and noticed these 2 things not plugged to where they should go... any ideas?

I think they're both related to the cat??

1 throttle position switch
2 looks like fuel breather pipe

^+1 Agreed.

should there be a plug er.. pluged into that then???

The elecrical plug might be redundant, there is a similar one in my car that is unconnected. The hose needs reconnecting though.

Electrical socket shown is definitely TPS.

Will move this to Tech Help, not Photo Gallery...

Connecting to what? If it's a breather pipe for the fuel tank it needs to be left as it is surely?

Where does the other end of the pipe go?
Does this car have a cat? (Or what age and model is the car?)

The open end of the rubber hose is marked by a hose clip, if it was meant to be left unconnected it would not have had a hose clip on it.

does it run at present?
without the tps plugged in

its a 325i tourer, it seems to run fine thats why i wonderd if they were ment to have plugs to em, i only noticed it when i was topping my water up

It will but the idle will be high, It wont drive very well at full throttle either.

The pipe looks to have had a clip around it so it need's re-connecting, but im not exactly sure what it's for from that pic.

looks like it may need to go to the throttle body
just a guess.if your happy now wait till you plug this in and the tps

This engine cannot possibly run anything like properly with the TPS disconnected!

il try and get a video of it tomorrow, iv had it over a month and its ran fine

I don't want video's! I want three simple questions answered!!!!!

Find the relays near the coolant bottle under a black cover and trace the wireing back, the TPS wire branches off from that not far down (less that 12" iirc) it's a 3 pin plug.

Once the ECU knows to use it's full throttle map you will see the differance, i did on my M20B20

See what you mean, which kind of indicates it's not a breather pipe as first suspected.

Means no such thing - depends on the spec of the car.
