Location for OIL PRESSURE SENSOR'S are, on Engine BLOCK At 90 degree angle BEHIND OIL FILTER , And One Just Above the Starter Poking out Same Direction as OIL FILTER, I would Suggest that you Replace Both at the same time, this IS NOT MANDATORY, But I have found it to be a time-saver and Sometimes it IS Necessary to replace them Both.

I have a pontiac bonneville 2002 ssei and the oil guage was usually between 40-80 when running. Now it is dropping to like 30 when just idling, what could cause this?

A number of things could impact this, a dirty oil filter, different type or weight, of oil or quite simply wear within the engine or oil pump (or combination of both)
First I'd get a gauge under the hood and get a true pressure check on the oil, perhaps the sending unit is failing. If it reads fine be certain the filter is clean. If still nothing it is within the engine, you can try to use a heavier oil that may increase your oil pressure.

I hope thi may have assisted you,

Where is the oil gauge switch on 2002 pontiac bonneville

i am assuming your car has the 3.8 liter v6. on the passenger side of the engine it is below the alternator and behind the power steering pump. it screws into an aluminum housing on the back side if the block.
first disconnect the wire harness connector and find a metric deep well socket or use a pair of channel lock pliers, but be carefull not to overtighten the oil pressure sending unit when use install it or you can
strip the threads in the housing or damage the plastic wire harness connector housing on the sending unit.

My 01 bonneville oil pressure gauge is showing 120 and my gas gauge is all over the place

HI, the oil pressure sending unit may be malfunctioning at this point. this will cause erratic readings. if your oil level is proper and there are no apparent oil leaks, you will need to replace the oil pressure sending unit. this will fix the erratic oil pressure readings.

Concerning the gas gauge. this device also has a sending unit that sends the correct fuel level reading to the gas gauge via wire transfer. this sending unit is located and attached to the fuel pump assembly inside the gas tank. replacing this device will fix this issue as well.

Please rate and god bless:)

Pontiac Bonneville(2000) oil pressure sending unit

The oil pressure sending unit is located behind the oil filter, Threaded into an aluminunm housing. It has wiring that plugs into the sending unit. The oil filter has to be removed and you will need a deep well socket and a 6 inch extension. Change the oil and the sending unit together.
