Hello,

My oil pressure gauge in my BNR32 reads low. At startup its at 2bar and then reads 1bar no matter what. I ordered a new sender from Nissan but I'm wondering if it could also be the gauge. Is it ever the gauge thats broken? Or is it always the sender?

Also to replace it I don't need to drain the oil do I?

Thanks
Mitch

PS: I did order some Defi Gauges but they will take a while to get to me. So I want to make sure my oil pressure is good in the mean time.

The sender unit is under the inlet plenum.

Screw it off with a snubby spanner, check oil pressure with a mechanical pressure tester gauge.

If happy, fit the new one,... wallah!

I don't really have access to a mechanical tester gauge. I guess I'll just give the sender a shot hopefully that fixes it.

Just installed a new sender unit, now oil pressure gauge is reading 2kg/cm^2 and moves until ~2.2kg/cm^2 even at 6000rpm.
