Code P2473 Dodge Description
The P2473 diagnostic trouble code (DTC) for Dodge vehicles indicates a problem with the Exhaust Gas Temperature (EGT) sensor circuit on Bank 2 Sensor 4. This sensor is responsible for monitoring the temperature of the exhaust gas as it exits the engine. The EGT sensor plays a crucial role in ensuring the engine operates efficiently and within safe temperature limits.
Common Causes of P2473 Dodge
- Faulty EGT Sensor: The EGT sensor itself may be defective or damaged, causing inaccurate temperature readings.
- Wiring Issues: Problems with the wiring harness connecting the EGT sensor to the ECM can lead to circuit malfunctions.
- ECM Malfunction: A malfunctioning Engine Control Module may not be able to properly communicate with the EGT sensor.
- Exhaust System Leak: An exhaust leak near the EGT sensor can affect its readings and trigger this code.
- Environmental Factors: Extreme temperatures or harsh driving conditions can also contribute to the failure of the EGT sensor.
Symptoms of P2473 Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in power and efficiency due to inaccurate temperature readings from the EGT sensor.
- Increased Fuel Consumption: A faulty EGT sensor can cause incorrect fuel injection, leading to higher fuel consumption.
- Rough Idling: The engine may idle roughly or inconsistently if the EGT sensor is not functioning correctly.
- Failed Emissions Test: If the EGT sensor is malfunctioning, it can lead to increased emissions, potentially causing the vehicle to fail emissions tests.
How to Fix P2473 Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific DTC and pinpoint the exact cause of the problem.
- Inspect Wiring and Connections: Check the wiring harness for any damage or loose connections that may be affecting the EGT sensor's circuit.
- Test EGT Sensor: Test the EGT sensor itself to determine if it is functioning properly or needs to be replaced.
- Repair or Replace Components: Depending on the diagnosis, repair or replace the faulty EGT sensor, wiring, or ECM.
- Clear DTCs and Test Drive: Once the repair is complete, clear the DTCs from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2473 Dodge
The cost of repairing the Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 4 can vary depending on the specific cause of the issue and the parts needed for the repair. On average, the cost of replacing an EGT sensor can range from $100 to $300, while addressing wiring or ECM issues may increase the overall cost. Labor rates at auto repair shops typically range from $80 to $150 per hour, but rates can vary based on location and shop.
