Default Coolant Temperature Sensor (ECT) location

Where is the Electronic Coolant Temperature (ECT) sensor located? I have a 1995 Legacy with an EJ22 engine.

I appreciate the help!

It's located at the back passenger side of the coolant cross-over pipe, which runs underneath the intake manifold. It's pretty tough to see/access with the intake manifold in place, but if you look down below the throttle body and towards the passenger side a bit you should see it. All the ones I've seen have a brown plastic connector.

I think the connector is of triangle shape.
Also the sensor (once you unscrew it and take it out) is about 5cm long.
You can examine its output with ECUexplorer to see if it gives reasonable values.

I'll have to get a bunch of hoses out of the way to get at it but it should be easy to do once I clear the way. I assume the single-wire sensor next to the ECT sensor is the sender for the temperature gauge. I'll be sure to clean up that connection.

Yeah, you're correct, the single wire sensor is for the temp gauge on the dash.

I think the newer models don't have the single wire sensor though....

Default Location on Loyale?

My loyale is coding a temp sensor fault. Haynes tells me to check it... but they don't say where it is! Where is the coolant temp sensor on the 1.8L (Nat. Aspirated MT) loyale engine?

Thanks!

I can't say for certain, but I wouldn't be at all surprised if it's located in the coolant cross-over manifold just like on the larger EJs.
