I broke the connectors trying to get them off when I was removing the intake manifold. Didn't seem like it should have been hard, they were twisting but would not slide off... What is this sensor anyway?

 

My guess would be the knock sensor. Is this an EA81T?

Yes, it's an EA81T.

Yeah - I would also guess knock sensor. I was thinking you were showing an EA82 block and they look different. The EA81T is very primitive so that makes sense

That's what I was suspecting.

 

Still haven't gotten those connectors off. Have to find some sort of replacement.

Be careful of the sensor itself (hard or impossible to find). They look like standard female bullet connectors once you get them off. Just solder them back on to the wires or retrofit something else.
