• Solutions

The P2415 fault code indicates an issue with the Oxygen (O2) sensor located in the exhaust system, specifically for Bank 2 Sensor 1. This sensor plays a crucial role in monitoring the level of oxygen in the exhaust gases, providing data to the engine control module (ECM) for optimal engine performance. A malfunction in this sensor can lead to inaccurate readings, triggering the check engine light and potentially causing increased emissions.

What are the symptoms of the P2415 code?

Symptoms associated with the P2415 fault code may include:

• Check engine light illuminated on the dashboard
• Decreased fuel efficiency due to incorrect air-fuel mixture
• Rough engine idle or performance issues
• Increased emissions during vehicle inspection
• Possible failure of emissions tests

What causes the P2415 code?

Common causes of the P2415 fault code include:

• Faulty O2 sensor for Bank 2 Sensor 1
• Wiring issues, such as frayed or damaged wires leading to the sensor
• Poor connections or corroded terminals at the O2 sensor
• Exhaust leaks near the sensor, impacting its readings
• Engine performance issues that affect the O2 sensor readings

How to fix P2415?

To resolve the P2415 fault code, the following steps are recommended:

• Inspect the wiring and connectors associated with Bank 2 Sensor 1 for any signs of damage or corrosion.
• Test the O2 sensor for proper functionality using a multimeter or scan tool to gauge its output.
• Replace the faulty O2 sensor if it is found to be non-functional.
• Repair any exhaust leaks that may be affecting the sensor's readings.
• Clear the fault code and perform a test drive to ensure the issue is resolved and the check engine light remains off.
