Do you know what causes the P2214 error code to get stored in the vehicle? If not, keep reading further. The DEF helps to change the remaining exhaust particles into harmless gases. If these particles have to be burnt off, the temperature of the exhaust system needs to be more and as the DEF fluid is inserted into the stream of the exhaust, it will push the DPF to the expected temperature. The dangerous NOx is then converted into nitrogen, CO2, and water by the system. The remaining NOx in the exhaust stream is reduced with the help of SRC. Numerous Nox sensors will be used by the PCM to check the reductant systems performance. Malfunctioning of at least one of the NOx sensor will set the P2214 error in the vehicle.

Numerous sensors at a given time can be easily looked after by the ECM so as to keep the engine functioning, reliable and effective. It also actively looks after the emission and guarantees that fewer hydrocarbons are let to the atmosphere. In order to get an idea of the hydrocarbon which is let into the atmosphere, the ECM will use a NOx sensor to monitor the levels of nitrogen oxide. Engines which are diesel-fuelled, produce NOx as the main PM’s. This is constantly looked after by the ECM and altered as needed. The unclean place in the vehicle is the diesel engine’s exhaust. The switches and sensors can turn out to be defective based on their location if there is black soot formed around the exhaust. This wouldn’t bother much if the soot does not own unique characteristics. The sensor will not be able to calculate the values which the ECM needs if there is so much debris as the ECM must constantly change the EVAP based on the federal/state/provincial laws. Occasionally, the aftermarket sensors will agree with the local emission standards as they pass from state to state.

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

• The catalytic converter might be damaged.
• The oxygen sensor might be faulty which also sends an oxygen sensor code and catalytic converter code.
• Some problem which signals the PCM that the failure of the catalytic converter may cause the P2214 error to be stored, which also includes the leakage in the exhaust manifold as well as other exhaust components like hoses and downpipes.

1. Diesel Exhaust Fluid - If the diesel exhaust fluid is poor, then the malfunctioning of the machine SCR’s system will take place. Replace it as soon as possible.
2. Exhaust System - If there is a loud roaring noise in the vehicle, then it’s high time to replace the faulty exhaust system and get rid of the P2214 error code.
3. Diesel Particulate Filter - Does your engine fail to start? Does your engine find it very hard to start or accelerate? Then the DPF can be faulty. Change it quickly.
4. Powertrain Control Module - If the sensor circuit is shorted it will overload the engine and damage the PCM module. If you find the powertrain control module to be damaged get the replacement from Parts Avatar.
5. Engine Control Module - Does your engine turn off without any reason? Then it’s a high time to replace your ECM as it can be faulty.
6. Nitrogen Oxide Sensor - If you are experiencing fewer miles per gallon than you normally do, then the nitrogen oxide sensor could have been damaged which needs immediate fixation.
7. Nitrogen Oxide Connector - The broken or damaged nitrogen oxide connector needs quick replacement to avoid P2214 error code.
8. Catalytic Converter - Engine misfiring is a sign of a defective catalytic converter. Repair or replace it with a new one to avoid the P2214 error code.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P2214 code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms

• Hydrocarbon emission might be enlarged.
• Flashing of the check engine light.
• Fuel economy might not be regular.
• Intermittent idle.
• More smoke.

Learn the ways with which you can correct this trouble code:

• Leaks in the exhaust system must be repaired.
• All the components and the electrical connections have to be checked and fixed.
• Catalytic converter replacement.
• NOX sensor, as well as its connector, must be altered.
• Changing the NOx sensors’ battery voltage feed circuit.
• PCM, as well as its linked control modules, must be checked and fixed.

However, if you face any issue then we have stocked a wide range of best-priced PCM, exhaust gas, oxygen sensors, indicator lamp, MIL (malfunction indicator lamp) and more to help you out in fixing your car.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2214 code to be stored:

• The OBD-II error code – P2214 is diagnosed with the help of a scanner.
• Initially, the technician will carefully check the error codes and see if there are any additional error code that is catalytic converter or oxygen sensor related error codes.
• If he finds these error codes, then he will gather the data as well as the freeze frame data to know as to when the error was set in the vehicle.
• Then the error codes will be cleared and the mechanic will test-drive the vehicle.
• If the error codes keep coming up, then the technician will carefully look at the wires as well as its connections, by checking if there are any corrosion or any other indications of shorted or loose connectors.
• Then the exhaust system has to be checked for leaky areas and the conditions are tracked and compared along with the manufacturer’s recommendation by using a temperature gun.
• The oxygen sensor, as well as the NOx sensor, will then be tested with the help of a voltage meter by narrowing down the data fields of the scanner to particular sensors.

Common mistakes when diagnosing the P2214 code

The common mistake which arises while diagnosing the P2214 error code is the faulty catalytic converter. This error code might arise very often and cannot be overlooked as you diagnose this code as it may give rise to the unnecessary replacement of the catalytic converter. Even at times, a faulty oxygen sensor can be the reason and it has to be fully examined before replacing any other components.
