Anyone know what this is called and where to get a new one? Metal and plastic in between oil filter and fuel filter on 22re. Looks like a block temp unit of some kind doesn't go through to a galley way oil or coolant, just screws in to block and attaches to wire harness. Knock sensor maybe?

 

Knock sensor.
Oil sending unit is below the oil filter

 

Any ideas on where to get one and how much

 

Your local parts place should have them. Or your local toyota dealer
