OBD-II Generic Error Code P2213: How to Fix It

Q: Can I drive my car with a P2213 error code?

In most cases, your vehicle will remain drivable with a P2213 code, but it is not recommended to ignore it for long. The fault can reduce fuel efficiency, increase harmful NOx emissions, and may cause your vehicle to fail an emissions inspection. On some diesel vehicles, persistent NOx sensor faults can trigger limp mode or additional restrictions, limiting engine performance.

Q: What does Bank 2 mean for error code P2213?

Bank 2 refers to the side of the engine that does NOT contain cylinder number 1. On a V6 or V8 engine, there are two cylinder banks. The specific location of Bank 2 varies by vehicle make and model, so always consult a vehicle-specific diagram or service manual to correctly identify which side of the exhaust system to inspect.

Q: How much does it cost to fix a P2213 code?

If only the NOx sensor needs replacement, parts typically range from $80 to $300 depending on the vehicle make, model, and sensor type, with labor adding $50 to $150 at a shop. However, if the issue is a faulty SCR catalyst, DPF, wiring harness, or ECM, repair costs can rise significantly — sometimes to $500 or more. Getting an accurate diagnosis before replacing parts is strongly recommended.

Q: Will a P2213 code cause my car to fail an emissions test?

Yes, in most regions a P2213 fault code will cause your vehicle to fail an emissions inspection. The check engine light will be illuminated, and the emissions control readiness monitors will likely be incomplete or flagged as failed. You will need to resolve the fault and complete a full drive cycle so readiness monitors pass before the vehicle can be re-tested.

Q: Can a bad DEF (Diesel Exhaust Fluid) level trigger P2213?

Yes, on diesel vehicles low, contaminated, or incorrect DEF fluid can cause the SCR system to malfunction, leading to abnormal NOx sensor readings and triggering fault codes like P2213. Always check DEF fluid level and quality as an early diagnostic step on diesel vehicles before replacing more expensive components.

Abstract

Error code P2213 indicates that the Nitrogen Oxide (NOx) sensor on Bank 2 of your vehicle is reporting a signal that falls outside the expected operating range. The NOx sensor monitors exhaust gases to help your vehicle's engine control module (ECM) manage fuel delivery and emissions systems accurately. Left unaddressed, this fault can reduce fuel efficiency, increase harmful emissions, and potentially trigger further drivetrain or emissions-related faults.
