Legendary
Definitely try the sender first...as already mentioned they are prone to failure.
GU PATROL 2011 Ti, with goodies...

just had a similar nightmare with the wife's patrol - bottom line we did a mechanical old fashioned gauge check where the sensor screws into the block - Nissan dealer supplied a sensor with too high a 'sender' pressure twice - a new oil pump was quoted at approx £1000 - did a'mechanical' comparison check with our other patrol through the rev range re. the manual and low and behold the oil pressure on this suspect engine is better than the everyday workhorse - have just done 1500miles with the suspect engine fitted with a non standard sensor at a cost of £9.50 instead of the Nissan dealer quote of £125 for the same thing - happy days

you can use the standard GM 0-90 Ohm sender - far more reliable (1965-1995 IIRC, single pin type) You can also use the later models found in Silverados (1995+) that are 3 pins, but its a bit of mucking about trying to get and rewire a male plug to adapt
the nissan sensors are rubbish - and more so when you look at the price.
you can also use 0-90 Ohm dual pole sensors have one side for pressure and one for the light
VDO have switchable Ohms pressure senders, just make sure it can be switched 0-90Ohm and not the 0-180 Ohm or 0-240 Ohm types)
