The car's computer is having trouble getting the right information from one of the oxygen sensors in the exhaust system.
The OBD-II code P2415 indicates an issue with the oxygen sensor's ability to properly sample the exhaust gases in Bank 2, Sensor 1.
The P2415 code is triggered when the Engine Control Module (ECM) detects an error in the exhaust sample taken by the oxygen sensor located in Bank 2, Sensor 1. This sensor is responsible for monitoring the amount of oxygen in the exhaust gases and providing feedback to the ECM to adjust the air-fuel mixture for optimal combustion.
• Check Engine Light illuminated
• Poor fuel economy
• Rough engine idle
• Faulty oxygen sensor
• Wiring issues or poor electrical connection
• Exhaust leaks near the sensor
ECM: Engine Control Module
Oxygen Sensor: A device that measures the oxygen level in the exhaust gases
• Use an OBD-II scanner to confirm the P2415 code.
• Inspect the wiring and connectors for damage or corrosion.
• Check for exhaust leaks near the sensor.
• Replace the faulty oxygen sensor.
• Repair or replace damaged wiring or connectors.
• Fix any exhaust leaks.

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regular maintenance checks
• Timely replacement of oxygen sensors
• Ensure exhaust system integrity
Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid ignoring the Check Engine Light.
Oxygen sensors may be covered under emissions warranty.
This code has been associated with sensor failures and exhaust leaks in various models.
Moderate – Should be addressed soon to avoid potential engine performance issues.
Driving with a faulty oxygen sensor can lead to increased emissions and may not comply with emissions regulations.
• Engine at operating temperature
• Vehicle running at idle
The oxygen sensor is located in the exhaust manifold or exhaust pipe on Bank 2, upstream of the catalytic converter.
Q: Can I drive with a P2415 code?
A: It's possible, but not recommended as it can lead to poor fuel economy and increased emissions.
Q: How often should oxygen sensors be replaced?
A: Typically every 60,000 to 100,000 miles, but refer to your vehicle's maintenance schedule.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
