What is p0522 in Jeep?

I am experiencing an unusual issue with my 2013 GC: The engine light is illuminated, indicating code P0522, which signifies a low voltage warning for the oil pressure sensor. Typically, this indicates an open circuit in the sensor, resulting in a constant pressure reading of 100 psi. However, in my case, pressure readings are still being displayed. When idling, the pressure remains at around 90 psi even when warm, which is elevated. When driving, it drops to approximately 50 psi, and upon returning to idle, it returns to around 90 psi. I suspect that the sensor is still the culprit but could there be another component causing these symptoms?

Did you check the actual oil pressure or just replace the sensor? I don’t know which Jeep you have but most OEM in dash gauges aren’t all that accurate.

When you say ‘no crank’, do you mean absolutely nothing or do you hear the starter solenoid clicking and lights dimming like the starter is trying to turn the motor but can’t? If your P0522 code was caused by low oil pressure rather than just a bad sensor you could have locked up the motor

The P0522 code signals low oil pressure sensor or switch input, often due to a faulty sensor, low oil, wrong oil type, wiring issues, or engine problems.

Check and change the oil if needed. Inspect the sensor and wiring for damage.

If no issues are found, diagnostic scanning or a mechanic’s help may be required.

I’ve been driving my Jeep around and noticed a check engine light come on. I ran a scan and got a code P0522. This means the engine computer is getting a low signal from the oil pressure sensor. In simpler terms, it’s like the engine isn’t reporting enough oil pressure, which could be a serious issue if there really is low oil pressure. Luckily, it seems a faulty sensor or wiring problem is more likely culprits than actual engine trouble. I’ll definitely check my oil level first, but then I might need to take my Jeep in for a mechanic to diagnose the P0522 code and make sure everything is running smoothly.

The code P0522 in your 2013 GC indicates a low voltage problem with the oil pressure sensor. While it’s common to suspect the sensor itself, especially if it’s giving a constant high reading like 100 psi, your situation is a bit different since you’re still getting variable readings. Here are some steps you can take to troubleshoot the issue:

Check the Oil Level: Ensure that the oil level is within the recommended range. Low oil levels can lead to low oil pressure, which might trigger the P0522 code.
Inspect the Oil Quality: Dirty or incorrect oil can affect the oil pressure readings. If the oil is due for a change, it’s worth doing so to eliminate this as a potential cause.
Test the Oil Pressure Mechanically: Use a manual oil pressure gauge to test the oil pressure directly. This will help you determine if the issue is with the sensor or if there’s an actual problem with the oil pressure.
Examine the Wiring and Connectors: Check the wiring and connectors for any signs of damage, corrosion, or loose connections. Repair or replace any damaged wiring.
Consider Sensor Replacement: If the wiring and oil levels are fine, and the manual oil pressure test shows normal pressure, the sensor might be faulty. In this case, replacing the sensor could resolve the issue.

Here’s a simplified guide to diagnosing and fixing the P0522 code (ENGINE OIL PRESSURE SENSOR CIRCUIT LOW) for a 2013 Dodge Dart L4-2.0L:

P0522 Code: Engine Oil Pressure Sensor Circuit Low

Symptoms:

  • The check engine light is on.
  • The oil pressure gauge may show incorrect readings.

Causes:

  • Faulty oil pressure sensor.
  • Wiring issues (short to ground).
  • Powertrain Control Module (PCM) issues.

Diagnostic Steps:

Step 1: Preliminary Checks

  1. Ensure the ignition is on and the battery voltage is above 10.38 volts.
  2. Check if any other 5-Volt reference DTCs are present. If so, address those first.

Step 2: Check DTC Status

  1. Start the engine and let it reach normal operating temperature.
  2. Use a scan tool to check if the P0522 code is active.
  • If Yes: Proceed to Step 3.
  • If No: Perform the Intermittent Condition diagnostic procedure.

Step 3: Check for Short to Ground

  1. Turn off the ignition.
  2. Disconnect the harness connectors from the Engine Oil Pressure Switch and the PCM (C2 connector).
  3. Measure the resistance between the ground and the (G6) Engine Oil Pressure Sensor Signal circuit at the Engine Oil Pressure Switch harness connector.
  • If the resistance is above 10k Ohms: Proceed to Step 4.
  • If the resistance is below 10k Ohms: Repair the short to ground in the (G6) circuit. Then perform the Powertrain Verification Test.

Step 4: Check Sensor Signal Circuit

  1. Reconnect the PCM C2 harness connector.
  2. Turn the ignition on.
  3. Use the scan tool to see if the PCM shows an Engine Oil Pressure Sensor Circuit High DTC with the sensor disconnected.
  • If Yes: Replace the Engine Oil Pressure Sensor. Then perform the Powertrain Verification Test.
  • If No: Proceed to Step 5.

Step 5: Inspect Wiring and Connectors

  1. Inspect the wiring and connectors between the Engine Oil Pressure Switch and the PCM.
  2. Look for any damaged wires or corroded terminals.
  3. Perform any applicable Technical Service Bulletins (TSBs).
  • If problems are found: Repair as necessary and perform the Powertrain Verification Test.
  • If no problems are found: Proceed to Step 6.

Step 6: PCM Replacement

  1. If no wiring issues are found and the problem persists, the PCM may need to be replaced and programmed.
  2. Replace and program the PCM following the manufacturer’s guidelines.
  3. Perform the Powertrain Verification Test.

Notes:

  • Always perform the Pre-Diagnostic Troubleshooting procedure before starting the diagnostic steps.
  • Use proper safety measures and tools when working on the vehicle.

By following these steps, you can diagnose and resolve the P0522 code effectively.

The P0522 code indicates a low voltage issue with the oil pressure sensor circuit, which can often be due to a faulty oil pressure sensor.

The P0522 code on a Jeep indicates a low oil pressure sensor or switch input. This problem could be caused by a defective sensor, a low oil level, the wrong oil type, wiring issues, or engine problems.

Have you replaced the sensor alone, or have you also checked the oil pressure? Although I’m not sure which Jeep you have, the majority of OEM dash gauges aren’t very accurate.
Do you really mean “no crank” or do you mean that you can hear the starter solenoid clicking and that the lights are fading as if the started is attempting to turn the motor but is unable to do so? You might have locked up the motor if low oil pressure rather than a faulty sensor was the reason for your P0522 code.
