P2217 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Do you know why the P2217 error code is stored in your vehicle? Are you looking for the symptoms and causes of this error? Then, look no further and keep reading ahead. The DEF helps to convert the excess exhaust particles to harmless gases. If you want to burn off those excess particles, the exhaust systems’ temperature has to be increased. As the DEF is injected, the exhaust stream will raise the temperature of the DPF as needed which then helps to convert the harmful NOx to nitrogen, CO2, and water respectively.

To minimize the NOx which is present in the exhaust stream, the reductant catalyst was added. To check the functioning of the reductant system, the PCM will use several NOx sensors. Failure of one of the NOx sensor will set the P2217 error in the vehicle.

The ECM will look after several sensors at any time so that the engine is effective, consistent and properly functioning. Apart from this, it also effectively monitors the emissions and ensures to eject very less hydrocarbons to the atmosphere as possible. The nitrogen oxide level is monitored by the ECM by using the NOx sensor within the exhaust so as to have a knowledge of the amount of hydrocarbons which is ejected. One of the primary PM’s that the diesel-fuelled engine produces is the NOx. The sensor is actively monitored by the ECM and altered as needed. The dirtiest place on the vehicle is the diesel engine exhaust. The soot which is formed in the exhaust of the diesel vehicle can damage the switches and sensors based on their location. This may not bother much if the soot does not own the characteristics. You will not be able to correctly measure the ECM’s values if the sensor is not free of debris as the ECM must alter the EVAP system as per the needed federal/state/provincial laws. When you go from one state to other, where emission regulations change, aftermarket sensors might sometime fulfill with local emission standards.

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

• The NOx sensor might be faulty.
• Unclean sensor pick up.
• Faulty wiring.
• Internal issues in the ECM.
• A problem in the connector.

1. Diesel Exhaust Fluid - If the DEF is contaminated, then the diesel exhaust fluid consumption by your engine system will be more. Replace the contaminated DEF instantly.
2. Exhaust System - Avoid the P2217 error code by replacing the damaged exhaust system if you see black smoke from the exhaust of the vehicle.
3. Diesel Particulate Filter - The DPF can turn out to be faulty if there is too much of power loss in the vehicle. Get rid of the defective DPF as soon as possible.
4. Powertrain Control Module - The PCM helps in generating output signals to control relays, actuators, and solenoids. If there is no proper output signal or if it is erratic then the PCM might be faulty. Fix the faulty PCM instantly
5. Engine Control Module - The behavior of your engine will be very erratic if the ECM is faulty or broken. Get it fixed or replaced as soon as possible.
6. Nitrogen Oxide Sensor - The common symptom that you will notice for a faulty nitrogen oxide sensor is the illumination of the engine light in the dashboard. Replace it immediately.
7. Nitrogen Oxide Connector - Fixing the damaged nitrogen oxide sensor connector can help to avoid the P2217 error code.
8. Catalytic Converter - The performance of the engine will be very poor if the catalytic converter is damaged. Avoid the P2084 error by changing the damaged catalytic converter.

Willing to know some common symptoms of OBD Code P2217? Your wish is our demand. Have a look at them below:

Common Symptoms

• Emissions of hydrocarbon are increased.
• Blinking of the check engine light.
• Fuel economy might not be constant.
• Unpredictable idle.
• Smoke might be extreme.

We have listed out some ways which would help you to correct the occurrence of OBD Code P2217. They are mentioned here as follows:

• Repairing the leaks in the exhaust system.
• Altering the catalytic converter.
• Fixing the malfunctioning oxygen sensor and NOx sensor.
• Replacement of the PCM, as well as its interrelated modules.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of PCM, exhaust gas, oxygen sensors, indicator lamp and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P2217 fault code:

• As a very first step, the mechanic will make sure that the error code is real so that he can reset the code and test drive the vehicle to see if it appears again.
• If the error shows up immediately, then the mechanic will diagnose the error which caused this error code to be stored and will make the necessary repairs like changing the oxygen sensor.
• If needed, the mechanic will also change or fix the damaged catalytic converter.
• Now examine the sensor as well as the harness.
• The very reason for the error can be the elements to which the vehicle is exposed to.
• Make sure that the sensor is intact and in proper condition as the curbs, rocks, snow, and ice can damage the sensors.
• The harness is always in close connection with the exhaust. So, there are chances that the electrical wires might get burnt or damaged which gives rise to a bigger problem. Allow the engine to cool, before you proceed to work near the exhaust.
• The sensor has to be cleaned properly.
• The sensor will go through numerous heating up and cooling up and you must be aware of it.
• The sensor expands and diminishes so often that they get caught at times in the sensor ‘bung’ on the exhaust.
• You have to apply heat to the threads in one such scenario. But it must not be applied straight on the sensor, as you may end up hurting the NOx sensor.
• It’s always best to skip this step if you haven’t tried applied heat to the free bolts and nuts.
• If you still have doubts in your own skills or abilities, it is best to take your vehicle to the nearby service station and hand it over to the trained mechanic.

Common Mistakes When Diagnosing the P2217 Code

• Damaged NOx sensor.
• Faulty PCM.
• Electrical wiring issue.
