Hello! I'm new to this site and hopefully i can get some useful tips out!

I've had these codes for awhile now, was told it was the fuel pump. Got it replaced along with a new o2 sensor. CEL still lights up. Also, did all the minor inexpensive easy fixes, no luck. I recently noticed an oil leak on top of the oil filter, possibly the oil pressure switch. Then i came to a realization, but not sure.

So my question is, Can the oil leaking through the oil pressure switch fall on the o2 sensor causing the problem? Still going to replace the OPS, but thought an answer on here would be faster than the anticipating success or fail.
