oil pressure sensor on 2001 Volvo S80

where is the oil pressure sensor and how is it replaced?

It's on the front side of the engine, under the intake manifold. If you have an oil light coming on, it's likely the oil pan seals are leaking internally and causing the oil pump to suck in air, causing the oil light to illuminate.
Very common issue on these engines.
replaced oil panseals light still stays on at idle
