oil pressure

2016 JKU Recently replaced oil filter housing/cooler with new aluminum one that come with new sensors. Now randomly the oil light pops up on the dash and the go to menu to check the oil pressure, it reads 0. It also seems to only happen going up hills. Everything seems to be running smooth...

I changed the oil in my 2015 JKU. I put mobil 1 5W-20 full synthetic. I put about 5.5 quarts in and swapped the filter n it seemed to run fine and the dipstick said level was right. Went to the store and when i got on it sounds like the rockers or lifters of ticking now. checked the cold level...

Does anyone have a work around for replacing the oil pressure sensor on a 2013 jeep wrangler JK with a 3.6 pentastar engine besides removing upper and lower intake? Thank you in advance
