Oil pressure sending unit
My check engine light came on yesterday, ran a diagnostics test and the code was for the Oil Pressure Switch Failure. After looking around for what to get it was the Sending unit itself. Has anyone done this fix by themselves and is it hard? Thanks guys.

It sounds as though you ran the HEC (Hybrid Electronic Cluster. aka instrument cluster) diagnostics test?
Thing is, that has nothing to do the with SES lamp, and PCM diagnostic trouble codes (DTCs) --read more about this here and you'll also find that the oil pressure sending unit code is a normal bug in these tests.
The only way to determine why the SES is on is to scan the OBD2 port with a DTC scanner.

Get the DTC numbers, not just the description. Many of the short form descriptions are very similar. the actual code is needed to diagnose properly...
When you get the DTCs look them up here.

None of what?
If you are referring to the codes provided by the instrument cluster diagnostics, none of them are listed in the powertrain DTC listing because they have nothing to do with the SES light or engine operation.
You need to read, or have read, the OBD2 codes with a scan tool connected to the OBD2 port which is by your right knee when you are sitting in the driver's seat.
The instrument cluster diagnostic mode, and the codes it can show, are of NO value in determining why the SES light is on--none...

. Well put on my O/R X and the light went off. I'm pretty sure that, even though I turned off the rear O2 sensors, one of them was loose or something. No more worrying. Guess I get to save my newly purchased Oil Pressure Sending unit for another day
