P0514 Dodge Code - Temperature Sensor Rationality
Quick Answer
The P0514 code in a Dodge vehicle indicates an issue with the temperature sensor rationality. Common causes include Faulty Temperature Sensor: A defective temperature sensor could be sending incorrect readings to the ECM, Wiring Issues: Damaged or corroded wiring connecting the temperature sensors to the ECM can cause signal discrepancies, ECM Malfunction: A malfunctioning ECM may not be able to interpret the temperature sensor data correctly, leading to the P0514 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 P0514 Dodge Description
The P0514 code in a Dodge vehicle indicates an issue with the temperature sensor rationality. This means that the Engine Control Module (ECM) has detected a discrepancy between the signals from the various temperature sensors in the engine. The ECM uses data from these sensors to regulate various functions, such as fuel injection timing, ignition timing, and idle speed control. When the temperature sensor readings do not align, it can lead to improper engine performance and potentially cause damage if not addressed.
Common Causes of P0514 Dodge
- Faulty Temperature Sensor: A defective temperature sensor could be sending incorrect readings to the ECM.
- Wiring Issues: Damaged or corroded wiring connecting the temperature sensors to the ECM can cause signal discrepancies.
- ECM Malfunction: A malfunctioning ECM may not be able to interpret the temperature sensor data correctly, leading to the P0514 code.
- Sensor Placement: Improper placement of the temperature sensors in the engine can result in inaccurate readings.
- Environmental Factors: Extreme temperatures or exposure to contaminants can affect the performance of temperature sensors.
Symptoms of P0514 Dodge
- Check Engine Light: The most common symptom associated with the P0514 code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Fuel Efficiency: A malfunctioning temperature sensor can lead to incorrect fuel delivery, resulting in decreased fuel efficiency.
- Engine Overheating: Inaccurate temperature sensor readings may cause the engine to overheat due to improper cooling system operation.
- Rough Idle: The engine may experience rough idling or stalling if the ECM is not receiving accurate temperature data from the sensors.
How to Fix P0514 Dodge
- Diagnostic Testing: Use a diagnostic scanner to retrieve the fault code and perform a thorough inspection of the temperature sensors and wiring.
- Replace Temperature Sensors: If a faulty temperature sensor is identified, replace it with a new, OEM-approved sensor.
- Check Wiring: Inspect the wiring harness for any damage or corrosion and repair or replace as needed.
- Reset ECM: Clear the fault code from the ECM and reset the system to see if the issue persists.
- Test Drive: After completing the repairs, test drive the vehicle to ensure that the issue has been resolved and that the check engine light does not reappear.
Cost to Fix P0514 Dodge
The typical repair costs for addressing a P0514 code in a Dodge vehicle can vary depending on the specific cause of the issue. In general, replacing a temperature sensor can cost between $50 to $200, including parts and labor. If wiring repairs are necessary, additional costs may apply. Diagnostic testing and labor rates at auto repair shops can range from $80 to $150 per hour. It is advisable to consult with a qualified mechanic or dealership to get a more accurate estimate based on the specific circumstances of your vehicle.
