P2213 - NOx SENSOR CIRCUIT BANK 2
Description of DTC code P2213
The Engine Control Module (ECM) is responsible for constantly monitoring the various sensors with which the vehicle is equipped to keep the engine running efficiently. It also monitors emissions so that as little as possible is released into the atmosphere.
The ECM uses the NOx Sensor (Nitrogen Oxide) to monitor the levels of this chemical compound inside the exhaust, and thus know the hydrocarbons that will be expelled. Because nitrogen oxide is highly produced in diesel engines, the ECM constantly watches this sensor to make system adjustments accordingly.
When the DTC code P2213 OBD2 is set, it is mostly because a fault was found in the NOx Sensor circuit of bank 2.
Symptoms of fault code P2213
- Check Engine light illuminated.
- Hydrocarbon emissions increase.
- Increased fuel consumption.
- An excessive amount of smoke comes out of the exhaust.
Causes of OBD2 P2213
The factors for which the P2213 OBDII diagnostic code is set are:
- Perhaps the Nitrogen Oxide Sensor is faulty.
- Nox Sensor wiring damaged.
- The Three-way Catalytic Converter (TWC) may have defects.
- Damaged wiring
- Internal ECM issue
- Connector problems
Possible solutions of the DTC code P2213
To troubleshoot the problems related to the P2213 OBD2 fault code are as follows:
- Check the Nitrogen Oxide Sensor along with its cables and respective connector. Check that the sensor has no elements that interfere with its proper functioning. Also, take into account that the wires may be exposed to high exhaust temperatures, so they may be damaged. Repair it as required.
- Clean the Nox Sensor and verify that it is properly installed and tightened.
- Replace the Nox Sensor.
