P1C55 Dodge Code - NOX Sensor Intermittent Bank 1 Sensor 1
Quick Answer
The P1C55 diagnostic trouble code (DTC) for Dodge vehicles indicates an intermittent issue with the NOx (nitrogen oxide) sensor in Bank 1 Sensor 1. Common causes include Faulty NOx Sensor: The sensor itself may be defective and not providing accurate readings, Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the signal from the sensor to the ECM, ECM Malfunction: A problem with the engine control module can prevent it from receiving or interpreting data from the NOx sensor correctly. 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 P1C55 Dodge Description
The P1C55 diagnostic trouble code (DTC) for Dodge vehicles indicates an intermittent issue with the NOx (nitrogen oxide) sensor in Bank 1 Sensor 1. The NOx sensor plays a crucial role in monitoring and controlling the levels of harmful emissions produced by the vehicle's engine. This specific sensor is responsible for measuring the amount of nitrogen oxide in the exhaust gases before they are released into the environment.
Common Causes of P1C55 Dodge
- Faulty NOx Sensor: The sensor itself may be defective and not providing accurate readings.
- Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the signal from the sensor to the ECM.
- ECM Malfunction: A problem with the engine control module can prevent it from receiving or interpreting data from the NOx sensor correctly.
- Exhaust System Leaks: Leaks in the exhaust system can affect the readings of the NOx sensor, leading to intermittent issues.
Symptoms of P1C55 Dodge
- Check Engine Light: The most common symptom of this DTC is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: An intermittent NOx sensor can lead to an improper air-fuel mixture, resulting in decreased fuel efficiency.
- Poor Engine Performance: The vehicle may experience rough idling, hesitation, or a lack of power when driving.
- Failed Emissions Test: If the NOx sensor is not functioning correctly, the vehicle may fail emissions tests due to high nitrogen oxide emissions.
How to Fix P1C55 Dodge
- Diagnose the Issue: Use a diagnostic tool to retrieve the specific DTC and perform further testing to pinpoint the exact cause of the intermittent NOx sensor.
- Inspect Wiring: Check the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring.
- Test NOx Sensor: Test the NOx sensor to determine if it is functioning correctly. Replace the sensor if necessary.
- Clear Codes: After the repair is completed, clear the DTCs and reset the ECM to see if the issue has been resolved.
- Perform Emissions Test: Once the repair is done, it is advisable to perform an emissions test to ensure that the vehicle is now compliant with regulations.
Cost to Fix P1C55 Dodge
The cost of repairing an intermittent NOx sensor in Bank 1 Sensor 1 can vary depending on the cause of the issue and the specific parts needed. On average, the cost of replacing a NOx sensor can range from $200 to $500, including parts and labor. However, additional costs may apply if wiring repairs or ECM diagnostics are required. It is recommended to consult with a professional mechanic or dealership to get a more accurate estimate based on the specific vehicle make and model. Keep in mind that labor rates can vary, so it is essential to inquire about rates in your local area before proceeding with the repair.
