The P2414 fault code indicates an O2 Sensor Exhaust Sample Error for Bank 1 Sensor 1. This code typically relates to the oxygen sensor's performance in measuring the oxygen levels in the exhaust system. It suggests that there is a problem with the sensor that affects its ability to accurately read the exhaust gases, which can result in poor engine performance and increased emissions.

What are the symptoms of the P2414 code?

Symptoms associated with a P2414 fault code may involve:

• Rough idling or stalling of the engine
• Decreased fuel efficiency and poor acceleration
• Increased emissions, potentially leading to failing an emissions test
• The Check Engine Light illuminated on the dashboard.

What causes the P2414 code?

Common causes of the P2414 code can include:

• Faulty oxygen sensor (Bank 1 Sensor 1)
• Exhaust leaks that affect sensor readings
• Electrical issues such as damaged wiring or poor connections
• Contamination or build-up on the sensor causing it to malfunction
• PCM (Powertrain Control Module) software issues.

How to fix P2414?

To address the P2414 fault code, the following steps are recommended:

• Conduct a visual inspection of the oxygen sensor and its wiring for damage or corrosion.
• Test the functionality of Bank 1 Sensor 1 with a scan tool to ensure it's operating within the correct parameters.
• Replace the faulty oxygen sensor if necessary.
• Inspect and repair any exhaust leaks that may be affecting sensor readings.
• Clear the fault codes and perform a test drive to ensure the issue is resolved.
