P2213

NOx Sensor Circuit Bank 2

Emissions / NOx sensor Generic OBD-II Medium

What it means

P2213 is a general circuit fault for the NOx sensor on bank 2 — the ECM can't get a valid reading from it. This sensor feeds the emissions (and SCR, on diesels) system. Drivability is usually normal, but the emissions monitor is affected, and the cause is typically the sensor, its wiring, or connector.

Medium

Can I keep driving? The engine runs normally, but the emissions/SCR system relies on this sensor; leaving it can trigger warning lights, failed emissions, and eventually a power derate on some diesels.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Faulty NOx sensor (bank 2)
  2. Open or shorted NOx sensor wiring
  3. Poor or corroded connector at the sensor
  4. Contaminated sensor tip or an exhaust leak near the sensor

How to diagnose & fix

Work through it in order

  1. Scan the NOx sensor live data and compare against a known-good range.
  2. Inspect the sensor connector and wiring for damage, shorts, or corrosion.
  3. Check for exhaust leaks near the sensor that could skew readings.
  4. Replace the NOx sensor if it won't report a valid signal with good wiring.
  5. Clear and complete a drive cycle to confirm.

FAQ

Quick answers

Is it safe to drive with P2213?+
Mechanically yes, but this is an emissions sensor — expect the light to stay on, possible emissions-test failure, and on some diesels a gradual power derate if it's ignored.
Can I just clear P2213?+
It returns while the sensor or wiring is faulty, and the emissions system stays flagged until it's repaired.
