P2215 - OBD Trouble Code

<<See All OBD Codes

Do you know what does NOx sensor circuit low bank 2 mean? Are you looking for the diagnostic procedures? Then keep reading further. The exhaust particles which are left behind is converter into harmless gases which is assisted by the DEF. the temperature must be high to burn these exhaust particles. As the DEF is injected in the exhaust stream, DPF will be raised to the expected temperature. This will finally convert the injurious NOx to nitrogen, CO2, and water.

If there is any NOx still present in the exhaust stream it will be reduced with the help of reductant catalyst. The proper functioning of the reductant system is confirmed by the ECM by utilizing numerous NOx sensors.

At any specific time, the ECM can easily monitor the numerous sensors to keep the engine properly functional, stable and effective. Apart from this, it also monitors the emission and makes sure that it sends very few hydrocarbons into the atmosphere. In order to monitor the NO2 level within the exhaust, the ECM will utilize the NOx sensor so that it gets a clear idea as to how much hydrocarbons is let out. Diesel fuelled engines usually produce NOx which is the main PM’s. It is keenly monitored by the ECM and adjusted accordingly. The unclean place in the vehicle is the exhaust of the diesel engine. The black soot that is formed around the exhaust can easily harm the switches and sensors based on their position within the exhaust. This wouldn’t be of a big issue if the soot didn’t possess the necessary characteristics. If there is too much debris in the sensor, it might be difficult to accurately measure the values which the ECM needs to change the EVAP system as per the federal/state/provincial laws. The aftermarket sensors might easily agree with the local emission standards as you move from state to state.

What causes this problem with the NOx Sensor Circuit Low Bank 2?

• The NOx sensor might be defective.
• The sensor pick up might be dirty.
• The wires might be damaged.
• An internal issue in the ECM.
• Issues with the connector.

If you are facing OBD error code P2215, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Hydrocarbon emission is more.
• Illumination of check engine light.
• Inconsistent fuel economy.
• Irregular idle.
• Increased smoke.

It is very important to fix the fault code P2215. So here are some ways with which you can correct this issue:

• Changing the leaky exhaust system.
• The damaged catalytic converter must be fixed.
• Replacing the defective oxygen sensor and NOx sensor.
• The PCM, as well as its other linked control modules, have to be repaired.

To do all this, you will need few high-quality auto parts such as Diesel Exhaust Fluid, Exhaust System, Diesel Particulate Filter, PCM, ECM, NOx sensor, NOx connector, catalytic converter and so on. From where will you get them? From your local store? Well, why go there when you can order quality parts with us while sitting in the comfort of your home. So, just browse through our website and order your needed parts today.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Carefully check the sensor as well as the harness.
• Most often, the elements to which our vehicle is exposed can be the reason for these issues.
• Often, the rocks, curbs, snow, and ice can damage the sensors and so make sure that the sensor is together and in good condition.
• Always keep in mind that the harness of the sensors is always in close connection to the exhaust.
• So there is a high chance that the wires might get molten or burnt resulting in severe issues.
• It’s always best to allow the engine to cool before you start working near the exhaust.
• Now you have to clean the sensor.
• You must be aware of the fact that the sensor which is placed in the exhaust goes through numerous cycles of heating and cooling down.
• Subsequently, they also expand and contract so many times that they get captured in the sensor ‘bung’ on the exhaust.
• If this is the scenario, then you must start applying the heat to the threads, but not directly on the sensor as you might damage the NOx sensor.
• If you haven’t tried practicing to apply heat to the free nuts or bolts, its’ always best to avoid this step.
• If you still have any doubts, it’s always best to leave your vehicle to a reputable service station and hand them over to a trained mechanic.

Common mistakes when diagnosing the P2215 code

• Faulty NOx sensor.
• Defective PCM.
• Issues with the wires.
