1. What Does the 2014 Dodge Avenger OBD2 Code P0520 Mean?

The OBD2 code P0520 for a 2014 Dodge Avenger means there’s a malfunction in the engine oil pressure sensor/switch circuit. This code is triggered when the car’s computer, known as the Powertrain Control Module (PCM), detects an irregular signal from the oil pressure sensor. The oil pressure sensor monitors the engine oil pressure, a critical parameter for engine lubrication and health. According to a study by the National Institute for Automotive Service Excellence (ASE), maintaining proper oil pressure is vital for preventing engine wear and tear. The PCM uses this information to ensure the engine is operating correctly and to alert the driver if there’s a problem. When the PCM detects that the oil pressure sensor’s signal is out of the expected range, it sets the P0520 code, turning on the check engine light. This could indicate a range of issues, from a faulty sensor to wiring problems or even low oil pressure.

Understanding the P0520 code involves recognizing its implications for your vehicle’s health. The sensor’s role in monitoring oil pressure is crucial because proper lubrication prevents excessive friction and wear between engine components. Ignoring this code can lead to severe engine damage.

2. What Are the Common Causes of the P0520 Code in a 2014 Dodge Avenger?

Several factors can trigger the P0520 code in your 2014 Dodge Avenger. Identifying the root cause is the first step in effectively resolving the issue.

• Faulty Oil Pressure Sensor: The sensor itself might be defective. Over time, sensors can degrade or fail due to exposure to heat, vibration, and contaminants.
• Wiring Issues: Damaged, corroded, or loose wiring connected to the oil pressure sensor can cause incorrect signals. According to a Bosch Automotive Handbook, wiring faults are a common cause of sensor malfunctions.
• Connector Problems: The connector that attaches the wiring to the sensor can become corroded or loose, leading to intermittent or incorrect readings.
• Low Oil Pressure: Actual low oil pressure due to a failing oil pump, clogged oil filter, or internal engine damage can also trigger the code.
• PCM Issues: Although less common, a malfunctioning Powertrain Control Module (PCM) can incorrectly interpret sensor signals or set the code in error.
• Incorrect Oil Type: Using the wrong type or weight of oil can affect oil pressure and sensor readings. Always refer to your vehicle’s manual for the correct oil specifications.
• Oil Leaks: Significant oil leaks can cause low oil pressure, leading to the P0520 code. Check for leaks around the engine, oil filter, and oil pan.

According to research published in the “SAE International Journal of Engines,” regular maintenance and inspection of these components can significantly reduce the likelihood of encountering the P0520 code. Addressing these potential causes promptly can help maintain your engine’s health.

3. What Are the Symptoms of the P0520 Code in a 2014 Dodge Avenger?

Recognizing the symptoms associated with the P0520 code can help you address the issue quickly, preventing further damage. Common symptoms include:

• Check Engine Light: This is the most obvious sign. The check engine light will illuminate on your dashboard.
• Oil Pressure Warning Light: In addition to the check engine light, the oil pressure warning light may also come on.
• Inaccurate Oil Pressure Gauge Reading: The oil pressure gauge on your dashboard may show unusually high or low readings, or it may not work at all.
• Engine Noise: You might hear unusual engine noises, such as knocking or ticking, due to inadequate lubrication.
• Reduced Engine Performance: The engine may exhibit reduced power or acceleration due to improper oil pressure.
• Engine Stalling: In severe cases, the engine may stall, especially at low speeds or when idling.
• Rough Idling: The engine may idle roughly, indicating inconsistent oil pressure affecting engine performance.
• Increased Engine Temperature: Inadequate lubrication can lead to increased friction and, consequently, higher engine temperatures.

According to a study by AAA, ignoring these symptoms can lead to more severe and costly engine repairs. Monitoring these signs and addressing them promptly can safeguard your vehicle’s engine.

4. How to Diagnose the P0520 Code in a 2014 Dodge Avenger?

Diagnosing the P0520 code requires a systematic approach to pinpoint the exact cause. Here’s a step-by-step guide:

1. OBD2 Scanner:
   • Connect an OBD2 scanner to your 2014 Dodge Avenger’s diagnostic port.
   • Read the trouble codes. Note all codes, including any pending or historical codes.
   • Clear the codes and take the car for a test drive to see if the P0520 code returns.
2. Visual Inspection:
   • Inspect the oil pressure sensor for any visible damage.
   • Check the wiring and connectors leading to the sensor for corrosion, damage, or loose connections.
3. Check Oil Level and Condition:
   • Ensure the oil level is correct. Low oil levels can trigger the P0520 code.
   • Check the oil for contamination or debris, which could indicate internal engine problems.
4. Oil Pressure Test:
   • Use a manual oil pressure gauge to verify the oil pressure.
   • Compare the reading with the manufacturer’s specifications. Low oil pressure can indicate a failing oil pump or other engine issues.
5. Sensor Testing:
   • Use a multimeter to test the oil pressure sensor’s voltage and resistance.
   • Compare your readings with the manufacturer’s specifications to determine if the sensor is functioning correctly.
6. Wiring and Connector Testing:
   • Use a multimeter to check the continuity of the wiring between the sensor and the PCM.
   • Check for shorts to ground or voltage in the wiring.
   • Ensure the connector is making good contact and is free from corrosion.
7. PCM Inspection:
   • If all other components check out, the PCM may be the issue.
   • Inspect the PCM for any signs of damage or corrosion.
   • Consider having the PCM tested or reprogrammed by a professional.

According to a study published in “Automotive Engineering International,” accurate diagnosis using diagnostic tools and methodical inspection can reduce repair times and costs. Follow these steps to accurately diagnose the P0520 code in your 2014 Dodge Avenger.
