It's below the front exhaust pipe LH side near to where the pipe fits to the engine.

W/shop manual says remove the front LH ex.pipe and LH side cat. for access.

One bolt holds the sensor along with its 'O' ring and electrical connection.

Please post your update!

The code you have is correct for that sensor.

It has a connector on top with removable plug, on picture it looks like two internal contacts.

Below this is the little bracket that holds it on, one bolt.

Looks like you remove bolt and pull it up.

Resistance accross the contacts approx 620 ohm

There is another test where you put a meter accross the contacts of the sensor

and place a magnet quickly past the sensor end, a very small intermittent voltage should be generated.

There are other tests involving the engine and ECT ECU, complicated!
