P2213 — NOx Sensor Circuit Bank 2
OBD2 code P2213 flags a problem with the sensor and actuator circuits (nox sensor circuit bank 2). The car is usually drivable while you plan the repair. Common culprits: blown fuse feeding the circuit, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.
powertrain (engine/transmission)
Is it safe to drive?
Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm P2213 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the nox sensor circuit bank 2 for damage, corrosion, chafing or poor contact.
- Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
- Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2213 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for P2213 (parts and labor, USD, independent shop rates): Replace the faulty sensor or actuator: $150–$500; Repair wiring or connectors: $80–$250; Control module repair: $300–$1,000. Overall, fixing P2213 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
What are the symptoms of P2213?
Drivers most often notice: possible limp mode depending on the affected component, Check Engine Light on, the affected system operates intermittently or not at all, increased fuel consumption in some cases.
What does OBD2 code P2213 mean?
OBD2 code P2213 flags a problem with the sensor and actuator circuits (nox sensor circuit bank 2). The car is usually drivable while you plan the repair. Common culprits: blown fuse feeding the circuit, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.

How much does it cost to fix P2213?
Replace the faulty sensor or actuator — $150–$500; Repair wiring or connectors — $80–$250; Control module repair — $300–$1,000. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.
What is the most common cause of P2213?
The most common causes are: blown fuse feeding the circuit, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.
What does P2213 mean?
When P2213 appears on a scan, it means the control module has flagged a problem in the sensor and actuator circuits: nox sensor circuit bank 2. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.
“Bank 2” means the side of the engine opposite to cylinder 1. Verify which side that is on your specific engine before testing or replacing parts.
To set P2213, the control module compares live readings of the sensor and actuator circuits against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.
What causes P2213?
- faulty sensor or actuator of the affected circuit
- control module driver fault
- open or shorted wiring in the circuit
- poor ground connection
