OK, i have 2012 jk 3.6. i have replaced so many parts. but....here we go again. my starter died, killed my battery...so I replaced them both, drove and sounded amazing then......next morning i got p0522 code on jscan, and the cel only comes on when it gets to normal operating temp. the oil cooler and sensors are mopar, 2 months old. i know its the right oil, i checked the oil level, good. but i broke it down and thought the oil cooler was leaking again because its the code i got when it leaked. but i cant see any leaks from the oil cooler. i did find a small leak from the passenger side valve cover but its small, it might be from the pcv valve hose, (i replaced it when i did the oil cooler), maybe knocked the hose loose when putting in new battery???? but either way...it wasnt there before. i dont know how to check the voltage or anything on the sensor. or how to do the piv for oil pressure on jscan and dont want to keep throwing parts at it if its not the problem. any help would be much appreciated, life is hard right now, and i kinda need a hand up. thank you
The P0522 code indicates that there's a problem with the engine oil pressure sensor or the circuit. Since you’ve recently replaced several parts, let’s break it down into manageable steps to help you diagnose the issue.
1. Inspect Wiring and Connector: First, check the wiring and connector to the oil pressure sensor for any signs of damage, corrosion, or loose connections. Sometimes, a bad connection can cause intermittent issues.
2. Testing Oil Pressure Sensor:
- If you have a multimeter, you can test the sensor. Disconnect it and measure the resistance at the sensor terminals with the engine off, then compare it to the specifications in your repair manual.
- You can also check the voltage supply to the sensor with the engine running. The signal wire should output a voltage that corresponds to the oil pressure.
3. Verify Oil Pressure: You can also verify the actual oil pressure using a mechanical gauge. This will help determine if the issue is with the sensor itself or if there’s a deeper problem with oil circulation.
4. Oil Level and Quality**: Although you’ve checked the oil level, ensure that it’s the correct type and hasn’t degraded. Sometimes, low-quality oil or the wrong viscosity can affect pressure readings.
5. PCV and Vacuum Leaks: Address the small leak from the passenger side valve cover. A vacuum leak can cause erratic engine behavior. Ensure the PCV valve hose is properly connected.
6. JScan Usage: To perform a PIV (parameter identification vehicle) test on JScan, you typically navigate to the "Diagnostic" section, look for live data and find oil pressure parameters to see if they fluctuate with RPM. The app should provide on-screen guidance.
7. Clearing Code: After performing checks and replacing any suspect parts, clear the check engine light and run the vehicle to see if the code returns.
If you’re still unsure about how to proceed with the electrical tests, consider reaching out to a local mechanic or someone with more experience in automotive diagnostics. Good luck, and hang in there!
