Default fault code question

Greetings, PT'ers! Just got 2 fault codes and I am wondering if one relates to the other? Codes are P 522 and P 137. I know that one is for a defective oil pressure sensor, but I am wondering if the other is also related to the pressure sensor. Thanks for any assistance!!

P0137: o2 Sensor Circuit Low Voltage Bank 1 Sensor 2.

Shouldn't have anything to do with the Oil Pressure sensor code. BTW, the PT only has one Bank so it's pointing to sensor 2 which is by the CAT.

Yeah....Replace your oil sensor,and your downstream(#2) O2 sensor,those codes should go away.......I would also recommend using only Mopar replacements,but you can use aftermarket(Dorman,Bosch,etc?),and if either of those codes returns,more than likely it'll be because the aftermarket part failed.
Money saving tip(s): You may want to check/clean-up the electrical plug for the #2 O2 sensor,the code could possibly be caused by just a faulty connection.
The OP sensor could also be checked/cleaned the same way,but it can sometimes back out (come loose) of the fitting,and cause the code.

But,depending on the exact age & mileage of your PT,it may just be time for replacements,as those are regularly serviceable/replacable parts.
