The P2213 fault code indicates an issue with the NOx sensor circuit in Bank 2 of the vehicle's exhaust system. The NOx sensor plays a critical role in monitoring nitrogen oxide emissions to ensure compliance with environmental regulations. When the sensor detects abnormal voltage levels or a failure in the circuit, the P2213 code is triggered. This can lead to increased emissions and potential engine performance issues.

What are the symptoms of the P2213 code?

Drivers may notice multiple symptoms associated with the P2213 code, including:

• Illumination of the check engine light
• Decreased fuel efficiency
• Increased exhaust emissions
• Rough engine idling or performance issues
• Failed emissions test during vehicle inspection

What causes the P2213 code?

Several factors can lead to the P2213 fault code, including:

• Faulty NOx sensor
• Damaged wiring or connectors in the NOx sensor circuit
• Poor connection at the sensor or the ECU
• Contamination or buildup within the sensor
• Issues with the engine's exhaust system that affect sensor performance

How to fix P2213?

To resolve the P2213 fault code, the following steps can be taken:

• Perform a thorough diagnostic to confirm the fault code and identify the underlying issue.
• Inspect the NOx sensor wiring and connectors for damage or corrosion and repair as necessary.
• Replace a faulty NOx sensor if testing indicates it is not functioning correctly.
• Clear the fault codes and test drive the vehicle to ensure the issue has been resolved and the check engine light remains off.
