P2213 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Do you know what are the symptoms and causes of the P2213 error code? Are you looking for the diagnostic steps to resolve them? Then look no further and keep reading ahead. With the help of the diesel exhaust fluid, the remaining exhaust particles are changed into harmless gas. These exhaust particles can be easily burnt only if the temperature of the exhaust system is very high. The diesel particulate filter DPF will move up to the required temperature when the DEF fluid is injected into the exhaust stream.

The dangerous NOx is then converted into nitrogen, carbon dioxide and water by the system. If there are any leftover NOx in the exhaust stream, they can be easily reduced with the help of reductant catalyst (SRC). The proper functioning of the reductant system is found by the engine computer by using several NOx sensors. If at least one of the NOx sensors fails to work normally, then the P2213 error will be set.

In order to keep the engine effective, stable and properly functioning, the ECM will look after the numerous sensors at any given time. Also, it will keenly monitor the emissions and ensures that it sends very fewer hydrocarbons to the environment as possible. The level of the nitrogen oxide is monitored with the help of NOx sensor by the ECM within the exhaust so that it gets an idea as how much hydrocarbon is ejected. NOx is considered to be the primary PM’s which is produced by the diesel-fuelled engines. It is actively monitored by the ECM and adjustments are made as needed. You must always keep in mind that the exhaust of the diesel engine is one of the dirtiest places in the vehicle. The soot that is formed around the diesel vehicle’s exhaust can damage the switches and sensors within then based on their position. This wouldn’t be bothering much if the soot does not comprise of the specific characteristics. It might be difficult to measure the values if the sensor has too much debris as the ECM will need them to adjust the EVAP as per the specific federal/state/provincial laws. As you move from one state to another where the regulations for emission keeps changing, the aftermarket sensors might at times obey with the local emission standards.

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

• NOx sensor might be broken.
• The sensor pick up might be polluted.
• Defective wirings.
• ECM might face an internal issue.
• Problematic connector.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2213 code by mentioning some major symptoms below:

Common Symptoms

• Emissions of hydrocarbon might be bigger.
• Check engine light might be illuminated.
• The fuel economy might not be reliable.
• Idling might be uneven.
• Too much smoke from the vehicle.

Have a look at some ways with which you can correct the P2213 code:

• The leaky areas in the exhaust system has to be fixed.
• Replacing the defective wires, connectors as well as other components.
• Changing the catalytic connecter if it is worse.
• The faulty oxygen sensor and NOx sensor must be altered.
• The defective PCM must be replaced and reprogrammed.

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of PCM, exhaust gas, oxygen sensors, indicator lamp, MIL and a lot more. We are sure that now all your issues would be resolved.

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

• Start checking the exhaust for any leaks.
• Reset both the trouble codes and the system.
• Carefully check the wires, connectors as well as other components for defects if the code returns.
• Test drive the vehicle by resetting the code and replacing all the required wires, connectors and components.
• If the code still keeps showing up, then use a scanner and download the freeze frame data and trouble codes that are stored.
• Carefully check the exhaust system by raising the vehicle on a lift and setting the engine at a normal operating temperature.
• The temperature of the exhaust must be checked before and after the catalytic converter with the help of a catalytic converter. Compare the values with that of the manufacturer’s specification.
• If the catalytic converter works perfectly, then check the upstream and downstream oxygen sensors with the help of a scanner along with oscilloscope and also the operation of the NOx sensor must be checked.
• Use a DVOM and check the upstream and downstream oxygen sensor as well as the NOx sensor.
• Clear the codes and check the system after fixing the defects.
• If the error still shows up, then separate the PCM as well as its linked control modules so that damages can be prevented and the resistance and continuity of various circuits must also be checked.
• Relate the findings to the manufacturer’s specification.
• If the NOx sensor, as well as the system circuits, perform well, then inspect the PCM as it can be faulty.
• After carrying out every repair, the technician has to clear the codes and test drive the vehicle to see if the error still shows up.

Common mistakes when diagnosing the P2213 code

An issue might arise in the vehicle when the faulty catalytic converter is not looked after for a longer period of time. If these situations are not fixed it might give rise to a bigger problem and results in the failure of the catalytic converter. A typical example of this situation is the conditions of a misfire of the engine which can harm the converters’ platinum element and leads to the failure which is not fixed. Changing the oxygen sensors by mistake is also another common mistake made by the mechanic. This might lead to the spending of the extra amount while the problem may still persist and the code keeps returning.
