05 Pacifica, 3.5L, 152k miles. My oil light comes on intermittently. Have been told that it may be a bad engine oil pressure switch. I would like to change the switch this weekend (part is $25 at Chrysler dealer parts desk).
Is this a bear to get to, to change? It looks like the switch is located at the front, lower left side of the engine. To get to it appears very challenging. Has anyone replaced this switch? Could the periodic oil light flash suggest something else?
Any directions, diagrams, instructions, suggestions, alternate ideas, and experience is much obliged...

OK, jacked the front-end up and looked up next to the oil filter and getting to the oil pressure sensor looks impossible (to me). I bought a new switch at a Chrysler Parts desk.
It looks like to get to it, I have to take off a cylinder looking thing (oil pump?) that is connected to the timing belt. Just removing the oil filter seems like not enough. The sensor is up and to the "right" (toward the passenger side). I can't even get an eye on it.
Can I get to the oil pressure sensor if I take off the lower front bumper cover? This looks like a "beyond Weekend Wrench" sort of a job.
this is all there is 10 min job use an oil pressure switch socket or an o2 sensor socket not a wrench
Raise vehicle on hoist.
Position an oil collecting container under switch location.
Disconnect electrical connector.
Unscrew oil pressure switch from oil filter adapter (Engine Oil Cooler and Filter Ad).
