Can someone enlighten me as to what this sensor is above the oil filter and below the vtec solenoid valve?

If it helps its bolted into the crank case and it attaches to the same part of the loom as the 2 vtec sensors do. it is bolted to the loom with a verysmall 7mm bolt as shown in the attached picture.

I think it may be the engine oil pressure sensor? or possible the engine oil temperature sensor?

Thanks

 

Oil pressure switch. Makes oil light turn on if low oil pressure detected.

 

Oil pressure sensor. Needs a wire connected to it!
