Jeep tossed codes P0520
Oil Pressure Sensor/Switch and P06DE
Engine Oil Pressure Control Circuit Stuck On in my lap. Engine was down on power.
Common fixes were listed as REPLACE SENSOR and REPLACE OIL PUMP respectively. Decided to replace the oil pressure sensor and change the oil to see if that would clear both codes. If not, the new oil would need to be drained and the oil pan removed to replace the oil pump.
Replacing the sensor requires removing the upper and lower intakes and the coolant temp sensor
Every thing was filthy
Removed the fuel rail and injectors and cleaned everything up
before reassembling with all new packings (O-rings to you non aviation types). Installed new oil & coolant sensors. That cleared all the codes. No need to replace the oil pump this time.
