Had a oil filter housing replacement done. Afterwards, the camshaft adjuster solenoid light was on. Replaced sensor, code would not clear and got 2 codes p0023/p0020. Car in limp mode. Mechanic changed all 4 sensors, checked wire connectors. Did oil flush, and oil change. Jeep still shows codes and in limp mode.. Help!
P0020 Code: Intake “A” Camshaft Position Actuator Circuit/Open (Bank 2) and P0023 Code: Exhaust “B” Camshaft Position Actuator Circuit (Bank 2).

These codes appear to indicate an open circuit on both the intake and exhaust Camshaft Position Actuator. I would check to make sure the electrical plugs for both Actuators are plugged in.
"V6 and V8 engines have 2 Banks, and Bank 1 is always the bank where cylinder number 1 is located – the other bank is Bank 2." In other words there's a Bank on each side of a V6 engine. For example, Bank 1 represents the 3 piston cylinders on the left side of the engine and Bank 2 represents the 3 piston cylinders on the right side of the engine.
'A' represents the intake camshaft position actuator and 'B' represents the exhaust camshaft position actuator.
