P2487 Code - Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 5
Quick Answer
The P2487 diagnostic trouble code (DTC) refers to a malfunction in the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 2 Sensor 5. Common causes include Faulty EGT Sensor: The most common cause of the P2487 code is a malfunctioning EGT sensor that is sending incorrect signals to the ECM, Wiring Issues: Damaged or corroded wiring connections between the EGT sensor and the ECM can lead to circuit high voltage readings, ECM Malfunction: A rare but possible cause of the code could be a fault within the engine control module itself. 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 P2487 Description
The P2487 diagnostic trouble code (DTC) refers to a malfunction in the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 2 Sensor 5. This sensor is responsible for monitoring the temperature of the exhaust gases after they have passed through the catalytic converter. The EGT sensor plays a crucial role in ensuring the proper functioning of the emissions system and helps the engine control module (ECM) adjust fuel delivery and timing for optimal performance and reduced emissions.
Common Causes of P2487
- Faulty EGT Sensor: The most common cause of the P2487 code is a malfunctioning EGT sensor that is sending incorrect signals to the ECM.
- Wiring Issues: Damaged or corroded wiring connections between the EGT sensor and the ECM can lead to circuit high voltage readings.
- ECM Malfunction: A rare but possible cause of the code could be a fault within the engine control module itself.
- Exhaust System Leak: A leak in the exhaust system before the EGT sensor can cause the sensor to read higher temperatures than actual.
- Overheating: Excessive heat in the exhaust system or engine compartment can also trigger the P2487 code.
Symptoms of P2487
- Check Engine Light: The most common symptom associated with the P2487 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Power: The engine may experience a decrease in power output or responsiveness due to incorrect fuel delivery and timing adjustments.
- Poor Fuel Economy: A malfunctioning EGT sensor can cause the engine to run inefficiently, leading to decreased fuel efficiency.
- Emission Failures: High exhaust gas temperatures can result in increased emissions, potentially causing the vehicle to fail emissions tests.
- Rough Idle: In some cases, the engine may exhibit rough idling or hesitation when accelerating.
How to Fix P2487
- Diagnostic: Begin by using a scan tool to retrieve the specific DTC and verify the issue with the EGT sensor circuit.
- Inspection: Inspect the EGT sensor, wiring, and connectors for any visible damage or corrosion. Repair or replace as necessary.
- Clear Codes: Clear the DTC from the ECM memory and test drive the vehicle to see if the code returns.
- Sensor Replacement: If the EGT sensor is faulty, replace it with a new sensor that meets the manufacturer's specifications.
- ECM Reprogramming: In rare cases where the ECM is at fault, reprogramming or replacing the ECM may be necessary.
Cost to Fix P2487
The cost of repairing a P2487 code can vary depending on the extent of the issue and the specific repairs needed. In general, the price for replacing an EGT sensor can range from $100 to $300, including parts and labor. However, additional costs may apply if wiring repairs or ECM reprogramming are required. It's important to note that labor rates at auto repair shops can vary widely, so it's advisable to check with local shops for a more accurate estimate.
