Encountering a check engine light in your 2014 Dodge Avenger can be concerning, especially when accompanied by unfamiliar OBD2 codes. If you’ve scanned your vehicle and found the code P0520, it indicates a potential issue with your oil pressure sensor circuit. This article will delve into what this code means, common symptoms, and how to approach diagnosing and resolving the problem.
The OBD2 code P0520 is generally defined as “Engine Oil Pressure Sensor/Switch Circuit Range/Performance.” In simpler terms, your car’s computer, or Powertrain Control Module (PCM), has detected an abnormal reading from the oil pressure sensor. This sensor is crucial as it monitors the engine’s oil pressure, ensuring that critical engine components are properly lubricated to prevent damage. When the PCM detects a signal from the oil pressure sensor that is out of the expected range, or if there’s a performance issue within the sensor’s circuit, it triggers the P0520 code and illuminates the check engine light.
Several symptoms may accompany the P0520 code in your 2014 Dodge Avenger. You might notice the check engine light is on, and potentially observe that your oil pressure gauge on the dashboard is not reading correctly – it could be stuck at low, high, or fluctuating erratically. In some cases, there might be no noticeable symptoms other than the illuminated check engine light. However, ignoring this code is not advisable as proper oil pressure is vital for engine health.
Diagnosing the P0520 code typically involves checking the oil pressure sensor, its wiring, and connections. A mechanic would usually start by visually inspecting the sensor and its circuit for any obvious damage. They might then use a diagnostic scan tool to further investigate the sensor’s readings and the circuit’s integrity. Common causes for this code can range from a faulty oil pressure sensor itself, wiring issues such as shorts or opens in the sensor circuit, or even low oil pressure conditions.
Repairing the P0520 code often involves replacing the oil pressure sensor. Depending on the diagnosis, other repairs might include fixing wiring problems or addressing underlying low oil pressure issues if they exist. While some car owners with mechanical experience might consider replacing the sensor themselves, it’s important to have the right tools and knowledge. If you’re uncomfortable with auto repair, seeking professional help from a certified mechanic is recommended to ensure the issue is correctly diagnosed and resolved, protecting the longevity of your 2014 Dodge Avenger’s engine.
Addressing the P0520 code promptly is crucial. Driving with low or fluctuating oil pressure can lead to significant engine damage over time. Therefore, once you’ve identified the P0520 code in your 2014 Dodge Avenger, it’s best to investigate and repair the issue as soon as possible to maintain your vehicle’s reliability and performance.
