P2219 - OBD Trouble Code

<<See All OBD Codes

Do you know what does P2219 error code refer to? How can this be resolved? Keep reading ahead. The temperature data and the exhaust composition from the oxygen sensor will be used by your vehicle’s PCM to find the input data of the NOx sensor circuit. The P2219 error code will get stored if the level isn’t found and the check engine light will be blinking. This error code is specifically related to bank 2 which means that it has the cylinder-2.

The required NOx sensor reading for each of the catalytic converter is found by the PCM by using the data which is sent from the downstream and upstream oxygen sensors. The downstream oxygen sensors will be stable than the upstream sensors as they tend to oscillate, mirroring the varying conditions of the fuel mixtures.

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

• An improper fuel usage.
• The coolant temperature sensor, manifold air pressure sensor, MAF sensor, fuel injection component or fuel pressure regulator might be faulty which allows more fuel to be dropped into the exhaust system.
• The ignition might misfire.
• There might be leakage in the flex hose, downpipe, exhaust manifold or a few other exhaust components which are located upstream from the catalytic converter.

1. Powertrain Control Module - Bad input from the sensors as well as other control modules will cause the malfunctioning of the PCM. Get the right replacement for your defective PCM at the best prices from Parts Avatar.
2. Engine Control Module - Corroded internal wiring harness can cause a short in the engine control module. Avoid the P2219 error in the vehicle by replacing the faulty ECM.
3. Exhaust Gas Temperature Sensor - Illumination of the check engine light and DPF light show that the temperature sensor is defective. Get rid of it as soon as possible.
4. Oxygen Sensors - Very poor idle or erratic jerking are the common symptoms for a damaged oxygen sensor. Replace the faulty oxygen sensor by getting a new one from PartsAvatar.
5. Nitrogen Oxide Sensor - There will be loud noise like thumping sound from the engine if the NOx sensor malfunctions. Get it replaced quickly to avoid P2219 error code.
6. Engine Wiring Connectors - The engine wiring connectors play an important role in connecting various components. Is the engine wiring connector broken? Get the replacement for faulty engine wiring connectors at affordable prices from PartsAvatar.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P2219 code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms

• At some instances, the P2219 error code may not be always visible.
• A few drivers might just notice a check engine light.
• Stalling of the engine might take place where the engine will hesitate to start.
• There might be hissing noise or other problems if the catalytic converter fail.

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

• The catalytic converter has to be fixed or changed.
• Alteration of the faulty oxygen sensors.
• Faulty electrical components need fixation.

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 P2219 fault code:

• As a very first and primary step, the mechanic will use an OBD-II scanner and read every code that is stored in the vehicle.
• This reading will also include the readings of the upstream and downstream oxygen sensor with the help of an oscilloscope.
• The same step will be repeated likewise for the NOx sensor which looks after the second engine bank.
• Every circuit, wires, and sensor have to be carefully checked by the mechanic.
• Also, the voltage has to be carefully inspected.
• The measured voltage has to be very close to that of the fully charged battery.
• If there are any stored error code, the mechanic will look for the faults and repair them accordingly.
• Once the repair is done, the system will be reset, the vehicle will be test-driven to see if the error codes appear again.
• This will help the technician to know if the issue was resolved or not.

Common Mistakes When Diagnosing the P2219 Code

• One of the common error that may arise when diagnosing the P2219 error is that the trained mechanic will fail to spend enough time analyzing as to what caused the catalytic converter to be faulty.
• As already mentioned above, this component might get easily damaged after a specific time of usage.
• Another common fault is changing the oxygen sensor before performing a complete analysis to make sure that it is not functioning accurately.
