Encountering trouble starting your 2012 Dodge Avenger can be frustrating, especially when accompanied by OBDII codes. If your scanner is showing codes P0339, P0335, and P0522, you’re likely dealing with issues related to your vehicle’s sensors. These codes, specifically P0339 and P0335 for Crankshaft Position Sensors and P0522 for the Engine Oil Pressure Sensor, can point to potential problems that might even leave you stranded. This guide will help you understand these codes, explore potential causes, and estimate the 2012 Dodge Avenger Obdii Code P0339 P0335 P0522 Repair Cost.
Understanding OBDII Codes P0339, P0335, and P0522
OBDII (On-Board Diagnostics II) codes are standardized codes used to identify potential issues within your vehicle’s systems. When your Dodge Avenger’s computer detects a problem, it illuminates the check engine light and stores a corresponding code. Let’s break down the codes P0339, P0335, and P0522:
- P0339 – Crankshaft Position Sensor “B” Circuit Intermittent: This code indicates an intermittent fault in the circuit for Crankshaft Position Sensor B. The crankshaft position sensor monitors the position and rotational speed of the crankshaft. This information is crucial for ignition timing and fuel injection. An intermittent signal can disrupt these processes, leading to starting problems or engine stalling.
- P0335 – Crankshaft Position Sensor “A” Circuit: Similar to P0339, code P0335 signals a malfunction in the circuit for Crankshaft Position Sensor A. This code suggests a more general issue with the sensor or its circuit, which can range from a faulty sensor to wiring problems. Like P0339, this can cause no-start conditions and engine performance issues.
- P0522 – Engine Oil Pressure Sensor/Switch Low Voltage: This code indicates that the engine oil pressure sensor is reporting a low voltage signal. This could mean actual low oil pressure, a faulty sensor, or a wiring issue in the sensor’s circuit. Low oil pressure is a serious concern as it can lead to engine damage.
While these codes can appear independently, their combined presence, especially in a no-start scenario for a 2012 Dodge Avenger, suggests a potential cluster of sensor-related or electrical issues.
Diagnosing the Issue: Step-by-Step Troubleshooting
When faced with a no-start condition and these OBDII codes, a systematic approach to diagnosis is crucial. Here’s a troubleshooting process you can follow:
-
Battery and Connections Check: Start with the basics. Ensure your battery is properly charged and holding a charge. Check the battery terminals and connections for corrosion or looseness. A weak battery or poor connections can cause a multitude of electrical issues, sometimes triggering seemingly unrelated sensor codes.

-
Inspect Sensor Wiring and Connectors: Visually inspect the wiring and connectors for both Crankshaft Position Sensors and the Oil Pressure Sensor. Look for signs of damage, fraying, or corrosion. Sometimes, rodents can chew on wiring harnesses, leading to intermittent sensor signals or complete failures. Ensure the connectors are securely plugged into the sensors.
-
Crankshaft Position Sensor Testing:
- Resistance Test: Use a multimeter to check the resistance of the Crankshaft Position Sensors. Refer to the 2012 Dodge Avenger repair manual for the specific resistance values. An out-of-range reading suggests a faulty sensor.
- Signal Test (If Possible to Start): If the engine can be started intermittently, use a scan tool or oscilloscope to check the signal output from the Crankshaft Position Sensors while cranking or running. An erratic or absent signal confirms a sensor issue.
-
Oil Pressure Sensor Testing:
- Oil Pressure Gauge Check: Manually check the engine oil pressure using a mechanical oil pressure gauge. This will help determine if the issue is actual low oil pressure or a faulty sensor.
- Sensor Voltage Check: With the ignition on, use a multimeter to check the voltage at the Oil Pressure Sensor connector. Compare this reading to the expected voltage specified in the service manual.
-
OBDII Scanner Data Monitoring: Utilize an OBDII scanner to monitor live data from the sensors. Observe the readings from the Crankshaft Position Sensors and the Oil Pressure Sensor while attempting to start the vehicle. This can provide valuable clues about sensor functionality and signal integrity.

PCM/ECM Inspection (Advanced): In rare cases, the Powertrain Control Module (PCM) or Engine Control Module (ECM) itself may be faulty. However, this is usually considered after ruling out sensor and wiring issues. PCM/ECM diagnosis often requires specialized equipment and expertise.
2012 Dodge Avenger OBDII Code P0339 P0335 P0522 Repair Cost
The repair cost for OBDII codes P0339, P0335, and P0522 on a 2012 Dodge Avenger can vary depending on the actual problem and the repair approach. Here’s a breakdown of potential costs:
-
Crankshaft Position Sensor Replacement:
- Parts: Crankshaft Position Sensors are relatively inexpensive, typically ranging from $30 to $80 each, depending on the brand and quality.
- Labor: Labor costs can vary from $100 to $300, depending on the location of the sensor and labor rates in your area. Some Dodge Avenger models may have easily accessible sensors, while others might require more involved disassembly.
- Total Cost per Sensor: Expect to pay between $130 and $380 per Crankshaft Position Sensor replacement. If both sensors are replaced, the cost will be doubled.
-
Oil Pressure Sensor Replacement:
- Parts: Oil Pressure Sensors are also reasonably priced, usually between $20 and $60.
- Labor: Labor for replacing the Oil Pressure Sensor can range from $80 to $250. Accessibility is a key factor here as well.
- Total Cost: The total cost for Oil Pressure Sensor replacement typically falls between $100 and $310.
-
Wiring Repair: If the issue is traced to wiring problems, the cost can vary significantly depending on the extent of the damage and the time required for repair. Wiring repairs can range from $50 to $500 or more.
-
PCM/ECM Replacement (If Necessary): PCM or ECM replacement is the most expensive scenario. A new PCM/ECM can cost between $500 and $1500 or more, plus labor for programming and installation, potentially adding another $200 to $500.
Estimated Total Repair Range:
Considering sensor replacements and potential wiring issues, the total repair cost for 2012 Dodge Avenger OBDII codes P0339, P0335, and P0522 could range from $230 to $1500 or more. It’s always recommended to get a precise quote from a qualified mechanic after a thorough diagnosis.
DIY vs. Professional Repair
For those with automotive repair experience, replacing sensors and checking wiring might be a DIY project, potentially saving on labor costs. However, accurate diagnosis is crucial. Misdiagnosis can lead to unnecessary parts replacements and continued problems.
If you are not comfortable with automotive diagnostics and repair, it’s best to consult a professional mechanic. They have the tools, expertise, and experience to accurately diagnose the root cause of the problem and perform the necessary repairs efficiently. A professional diagnosis can also help avoid throwing parts at the problem and ensure the issue is resolved correctly the first time.
Conclusion
Dealing with OBDII codes P0339, P0335, and P0522 on your 2012 Dodge Avenger can be concerning, especially when it leads to starting issues.
