P2485 Code - Exhaust Gas Temperature Sensor Circuit/Open Bank 2 Sensor 5
Quick Answer
The P2485 code indicates a problem with the Exhaust Gas Temperature (EGT) sensor circuit for Bank 2 Sensor 5. Common causes include Faulty EGT Sensor: The most common cause of the P2485 code is a malfunctioning EGT sensor for Bank 2 Sensor 5, Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can also trigger this code, ECM Malfunction: A problem with the engine control module (ECM) could be causing the EGT sensor circuit to malfunction. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2485 Description
The P2485 code indicates a problem with the Exhaust Gas Temperature (EGT) sensor circuit for Bank 2 Sensor 5. This sensor is responsible for monitoring the exhaust gas temperature in a specific section of the exhaust system. The EGT sensor plays a crucial role in helping the engine control module (ECM) regulate fuel injection timing and quantity, as well as monitor the performance of the diesel particulate filter (DPF) system in diesel vehicles.
Common Causes of P2485
- Faulty EGT Sensor: The most common cause of the P2485 code is a malfunctioning EGT sensor for Bank 2 Sensor 5.
- Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can also trigger this code.
- ECM Malfunction: A problem with the engine control module (ECM) could be causing the EGT sensor circuit to malfunction.
- Exhaust System Leak: An exhaust system leak near the EGT sensor can lead to incorrect temperature readings and trigger the P2485 code.
Symptoms of P2485
- Check Engine Light: The most common symptom associated with the P2485 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Engine Power: The vehicle may experience a loss of power or sluggish acceleration due to incorrect fuel injection timing caused by the malfunctioning EGT sensor.
- Increased Emissions: A faulty EGT sensor can lead to increased emissions, which may cause the vehicle to fail emissions tests.
- Rough Idling: The engine may idle roughly or inconsistently due to the improper fuel injection caused by the malfunctioning sensor.
How to Fix P2485
- Diagnose the Issue: Use a diagnostic scanner to confirm the P2485 code and perform a visual inspection of the EGT sensor and its wiring.
- Replace the EGT Sensor: If the sensor is faulty, replace Bank 2 Sensor 5 with a new one according to the manufacturer's specifications.
- Repair Wiring: If there are any damaged or corroded wires, repair or replace them as necessary.
- Clear Codes: After completing the repair, clear the codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2485
The cost of repairing the P2485 code can vary depending on the make and model of the vehicle, as well as the location and labor rates of the auto repair shop. On average, the cost of replacing an EGT sensor can range from $150 to $300, including parts and labor. Additional costs may apply if wiring repairs or ECM diagnostics are necessary. It is recommended to contact local auto repair shops for a more accurate estimate based on your specific vehicle.
