Oil light

[maldotcom2]

I would have thought the oil light would come on when i unplug the sensor, but it doesn't. Does it only come on when there is actually a signal for low oil pressure or is there a problem?

[wamboin23]

only when there is no/low pressure.

all the oil pressure switch does is earth the warning light, so disconnecting means no circuit at all.

Ok thanks for clearing that up.
