if the 3ed brake light works , rapidly move hazard switch back & forth & recheck, if they now work change turn signal switch , they are being canceled by switch

SOURCE: 2002 jeep wrangler oil pressure gauge drops

When the gauge is at 0, is there any noise from the engine (tick, knock etc?) I would have someone put a mechanical gauge on there and read true pressure.Your driving pressure seems OK but if the low number is "real" something is wrong!

Check for a bad fuse, or a bad/misadjusted brake switch.

It can be a problem with one of the injectors. What is odd it that the ECU has not set a code for a misfire. I would have the ECU scanned even if your check engine light is not on. With a misfire the ECU should have set a code on which cylinder is missing. I would suspect one of the injectors is malfunctioning.
