Help ID'ing Plug on Forester- Got it.- Thanks!

[wtdash]

EDIT: well, not really, but I got the engine installed and started it up - No CELs, so hoping/guessing it was 'extra'..

 

 

Hi,

1998 Forester - 5-speed.

I'm reinstalling the engine and failed to label the plug circled below. I can't find its mate (it might be unused). It's on the 5-speed's bellhousing near where the 3 big, main plugs connect.

Thanks,

TD

First guess due to location and contacts is probably O2 sensor. And the ohter end fell down by the Y-pipe and you don't see it.

Unfortunately, it's not the O2 as that plug is more oval and I'm very familiar w/it (due to changing it multiple times on previous Subies).

 

But I appreciate the reply.

 

Edit: It's more a triangle shape. :-)

can you take a wider pic please so I can find it on the FSM

O2 was my first guess. O2 sensors look different on different subaru's, there are various 1 to 5 wire styles. Sounds like you're sure so I can't think of what it is. I just did a 99 EJ swap and there's nothing in that area electrical that I disconnected.

 

Sort of looks like the master cylinder plug but that's the wrong side. How many wires does it have?

 

Did you check everything non-engine related - like cruise control - a/c components, etc back there? Maybe it was a connection that wasn't necessary to unplug for removal?

 

Or put it all back together and see if it fires up?

That's not the female plug on the bottom right corner of your white circle??

[logic23]

im pretty sure that is one of the two wires that goes to the transmisson. There should be a grey on and a red one. The other end is most likely sitting on the top of the trans.

Knock sensor?? located in the mid driver side of the engine under the intake manifold.

Sir N,

I went ahead and put it back together before I thought to take a better pic. :-(

 

But thanks for the offer.

Thanks all....it's 'none of the above'. But I appreciate the replies.

 

(The one empty plug is the 02, but I ID'd that one.)

 

 

There are 2 wires - 1 white and 1 black w/white stripe - going into the plug.

 

I'm going to just fire it up and see if I get a CEL...hopefully tomorrow.

 

Thanks,

Td
