What P2213 means
P2213 mirrors P2200 for the second cylinder bank: the NOx sensor serving bank 2 ahead of its SCR catalyst reports a general electrical fault. That presumes an engine whose banks feed separate aftertreatment lines. No manufacturer documents P2213 publicly; even V8 diesels such as GM's 6.6L Duramax, Ford's 6.7L and the Cummins 5.0L in Nissan's Titan XD route both banks into a single SCR line and use bank 1 codes only. As a guide, GM's LML logs P2200 when the smart sensor keeps signalling an interrupted wire for 0.5 or 10 s, and Ford adds probe-line shorts and checksum errors inside the sensor controller. CARB requires circuit faults on NOx sensors to be caught. P2214 to P2217 cover the other bank 2 signal faults.
P2213 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2213
- Malfunction indicator lamp on
- No NOx value from the bank 2 sensor in live data
- SCR warning, possibly with an inducement countdown
Common causes of P2213
- Most likelyInternal fault in the bank 2 NOx probe or its sensor control unit
- PossibleHeat-damaged or chafed lead between probe and sensor control unit
- PossibleWater or corrosion in the bank 2 sensor connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2213 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 13 | The exact fault in that area. |
What to do next
- Note P2213 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2213
What does P2213 mean?
P2213 means "NOx Sensor Circuit (Bank 2)". P2213 mirrors P2200 for the second cylinder bank: the NOx sensor serving bank 2 ahead of its SCR catalyst reports a general electrical fault. It is a generic code, so it means the same on every make.
Is it safe to drive with P2213?
Drive gently and only to a workshop. With P2213 the car can go into limp mode (reduced power) to protect itself.
Will P2213 fail an emissions test?
Yes, it can. P2213 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2213 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2213 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
