Error Code P2216: What It Means & What To Do?

<<See All OBD Codes

Are you looking for information with respect to NOx sensor circuit high bank 2? Then you are at the right place and keep reading ahead to gather more information. The exhaust particles in the vehicle are converted to gas which is harmless, and is assisted by the DEF. the temperature must be increased to burn these remaining exhaust particles. The exhaust stream will bring the DPF up to the needed temperature when the DEF is injected into it, where the dangerous NOx in the system is then converted into nitrogen, carbon dioxide, and water.

The reductant catalyst can be added more if the NOx was still present in the exhaust system. The proper functioning of the reductant system is checked with the help of multiple sensors by the PCM. The P2216 error will be set if at least one of the NOx sensors malfunctions.

The ECM looks after numerous sensors at any particular time to keep the engine steady, effective and efficient. It makes sure that very less hydrocarbon is let out in the atmosphere and monitors the emission very actively. The ECM will get an idea about the number of hydrocarbons that is left into the atmosphere when it uses the NOx sensor and monitors the nitrogen oxide levels. NOx is the main primary PM’s which is produced often by the diesel fuelled engines. The system will be adjusted as needed and the sensor will be regularly monitored by the ECM. Always remember that the muddiest place on the vehicle is the diesel engines’ exhaust. The switches and sensors within the exhaust can be easily damaged based on the location when black soot is formed in the exhaust of the diesel vehicle. A sensor which is not free of rubbles might find it difficult to calculate the values which the ECM needs to alter the EVAP system according to the state/provincial/federal laws. In some situations, the aftermarket sensors will easily agree with the local emission standards as they move from state to state.

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

• Broken NOx sensor.
• The sensor pick up might be unclean.
• The wires might be defective.
• ECM might have internal problems.
• Connector might face some issues.

1. Diesel Exhaust Fluid - The shutdown or de-rating of the engine system may take place if the diesel exhaust fluid is very poor. Change it quickly to avoid the P2216 error code in the vehicle.
2. Exhaust System - Do you hear strange noises from the engine? Then it is a sign that the exhaust system is malfunctioning which needs a very quick replacement.
3. Diesel Particulate Filter - A very hard acceleration is an indication that the diesel particulate filter is faulty. Replacing it quickly can help you to avoid the P2216 error code.
4. Powertrain Control Module - Malfunctioning of the powertrain control module can arise due to power relay or voltage issues. Changing the defective PCM can help you to get rid of the P2216 error in your vehicle.
5. Engine Control Module - Engine stalling is one of the symptoms for a defective ECM which needs replacement as soon as possible.
6. Nitrogen Oxide Sensor - The vehicle will lose mileage and the acceleration will be poor if the nitrogen oxide sensor is faulty. Avoid the P2216 error by replacing the damaged nitrogen oxide sensor.
7. Nitrogen Oxide Connector - Is the nitrogen oxide broken? Are you looking to replace the damaged NOx connector? Get them from Parts Avatar at an affordable cost online.
8. Catalytic Converter - A leaky exhaust valve is a sign of a defective catalytic converter. The damaged catalytic converter has to be replaced as soon as possible.

Here are some steps which you should follow in order to diagnose this P2216 fault code:

• The primary step is to carefully check the sensor as well as the harness.
• In most scenarios, the error can actually arise because of the elements to which the vehicle is exposed.
• The sensors are always supposed to be in proper condition and remain intact as the ice, rocks, curbs, and snow can easily cause the failure of the sensors.
• Even at times, the electrical wires can be easily burnt or molten and cause every issue in the vehicle as the harness remain very close and intact to the exhaust.
• Allowing the engine to cool down before working near the exhaust is always the best idea.
• The sensor has to be cleaned properly.
• Be aware that the sensor is always located in the exhaust and it will go through several cycles of cooling and heating up.
• Likewise, they enlarge and diminish so many times that they get caught in the sensor ‘bung’ which is the threaded hole on the exhaust.
• If you are experiencing this scenario, then the heat has to be applied but not directly on the sensor, because you can damage the sensor unknowingly.
• If you are new to applying heat to the breaking nuts and bolts then it is wise to skip this step.
• Similarly, if you doubt your own potential and skill, take your vehicle to the nearby service location and give it to the professionals as they can handle the situation much better.

Common Mistakes When Diagnosing the P2216 Code

• Defective NOx sensor.
• Damaged PCM.
• Problematic wires.
