P051C Dodge Code - Crankcase Pressure Sensor Circuit Low
Quick Answer
The P051C diagnostic trouble code for Dodge vehicles indicates an issue with the crankcase pressure sensor circuit registering a lower than expected voltage. Common causes include Faulty Sensor: The crankcase pressure sensor itself may be malfunctioning, registering lower voltage readings than expected, Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can disrupt the signal and trigger this code, ECM Malfunction: A malfunctioning ECM can also cause erroneous readings from the sensor, leading to this code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P051C Dodge Description
The P051C diagnostic trouble code for Dodge vehicles indicates an issue with the crankcase pressure sensor circuit registering a lower than expected voltage. The crankcase pressure sensor is a crucial component that measures the pressure inside the engine's crankcase. This information is essential for the engine control module (ECM) to optimize fuel delivery and ensure proper engine performance. When the sensor circuit records a low voltage, it can lead to incorrect fuel mixture, inefficient combustion, and overall decreased engine performance.
Common Causes of P051C Dodge
- Faulty Sensor: The crankcase pressure sensor itself may be malfunctioning, registering lower voltage readings than expected.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can disrupt the signal and trigger this code.
- ECM Malfunction: A malfunctioning ECM can also cause erroneous readings from the sensor, leading to this code.
- Vacuum Leaks: Any vacuum leaks in the engine system can affect the pressure readings, causing the sensor to report inaccurately.
Symptoms of P051C Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Engine Misfires: Decreased engine performance, rough idling, and potential misfires can occur due to incorrect fuel mixture caused by the faulty sensor.
- Decreased Fuel Efficiency: The ECM may not be able to adjust fuel delivery accurately, leading to decreased fuel efficiency.
- Engine Stalling: In severe cases, the engine may stall due to inconsistent fuel delivery caused by the sensor issue.
How to Fix P051C Dodge
- Diagnostic Testing: Begin by conducting a thorough diagnostic test to confirm the exact cause of the code and ensure it is related to the crankcase pressure sensor circuit.
- Sensor Replacement: If the sensor is faulty, it will need to be replaced with a new one. Ensure the replacement sensor is OEM or high-quality aftermarket to guarantee proper functioning.
- Wiring Inspection: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
- ECM Check: Verify that the ECM is functioning correctly and reprogram it if necessary to resolve any issues related to the sensor circuit.
- Clearing Codes: After completing the repairs, clear the diagnostic trouble codes from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P051C Dodge
The cost of repairing a crankcase pressure sensor circuit low issue can vary depending on the specific cause of the problem and the labor rates in your area. On average, the parts cost for a new sensor can range from $50 to $150, while the labor cost can be between $100 and $200. Additional costs may apply if wiring repairs or ECM reprogramming are necessary. It's recommended to consult with a trusted mechanic or dealership to get an accurate estimate based on your vehicle's make, model, and location.
