Checked oil level and it is OK. oil tempature is fine.
Light sometimes goes off. Also hear a buzzing noise or humm that goes up in pitch as I speed up. Goes away when clutch is pressed in. Just recently had the oil changed. Light came on after I had driven about 200 road miles. Should I replace the pressure sensor and where is the sensor located?
