P219E OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P219E can be explicated as Cylinder #3 Imbalance Error. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

It is the engine control module which would examine the cylinder 3. This trouble code would be set by the ECM when the number three cylinder would not be as per the parameters set by the manufacturer. A zirconium dioxide sensing element is used to construct each oxygen sensor which is situated in the center of a vented steel housing. There are some tiny electrodes (generally of platinum) which are attached to the sensing element to wire which would lead in the oxygen sensor harness connector and the connector plugs into the controller area network (CAN) which would then connect the oxygen sensor wiring harness to the PCM connector.

What causes this problem with the Cylinder #3 Imbalance Error?

• The engine compression might not be enough
• Unusable mass air flow or manifold air pressure sensor
• Imperfect wiring and/or connectors
• Broken oxygen sensor/s
• Defective CKP or CMP sensor

1. Oxygen Sensor - If the fuel to air ratio is not correct, the engine may work in lean or rich conditions. This not only hampers the performance output, but also affects the fuel economy, exhaust emissions and acceleration. Thus, a faulty oxygen sensor must be replaced as if it important for keeping in checks the oxygen levels entering/exiting the engine.
2. Engine Control Module - The solenoid might cause a short in the engine control module because of corrosion in the solenoid or the wire running from the solenoid to the ECM harness.
3. Fuel Pump - A faulty pump with low pressure will disturb the engine's air-fuel ratio, which can cause all sorts of performance problems. Aside from hard starting, the vehicle may experience misfires, a loss in power and acceleration, a decrease in fuel efficiency, and even engine stalling. Buy new fuel pump from us!
4. Electronic Control Unit - The ECU power management control module keeps in check the hybrid battery charging functions. If the ECU is faulty, the battery pack will not be able to properly get charged and thus, the ECU might need replacement.
5. Fuel Injector - If there is a leakage in the fuel injectors, then it might cause a rise in the fuel consumption, fuel odours around the vehicle and hard starting. You can always rely on us as we have best auto parts for our customers.
6. Powertrain Control Module - A trouble with the PCM would mean that it is unable to determine the right fuel mixture and would send the car engine either more or less fuel than it requires. Now when the engine gets more, the carbon emission would increase and fuel economy would drop. In case of the opposite, the engine will choke, stutter, and might start stalling sometimes.
7. Diagnostic Tool - Usually any OBD code problem requires deep insight into the problem and high-grade tools in order to fix it properly. Thus, buy quality diagnostic tools form us!

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P219E here:

Common Symptoms

• Illumination in the service engine soon light
• Decline in the fuel efficiency
• Decrease in the general engine performance
• Storage of misfire codes or lean/rich exhaust codes

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P219E:

• Repair or replace the quirky oxygen sensor/s
• Rehabilitate the defaults in the CKP or CMP
• Make sure to mend the faulty wiring and/or connectors
• Recondition the non-functioning mass airflow or manifold air pressure sensor
• Adjust the flawed ECU

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

• The car mechanic should make sure to address the misfire codes, throttle position sensor codes, manifold air pressure codes, and mass air flow sensor codes. Make sure that the car engine is running smoothly and efficiently. If there is an existence of rich or lean condition, then make sure to repair as it might be the leading cause of the P219E being stored. In order to correctly diagnose the code P219E, the mechanic would need a diagnostic scanner, a digital volt/ohmmeter (DVOM), and a source of reliable vehicle information.
• You can always search for technical service bulletins (TSB) that replicate the code stored, vehicle (year, make, model, and engine), and symptoms exhibited. This information can be easily found in your vehicle information source. If you are able to search for the correct TSB, then it can yield a speedy solution to your diagnosis. Now once the scanner has been connected to the vehicle diagnostic port, then you should retrieve all stored codes and pertinent freeze frame data.
• One can always write down this information in case the code proves to be an intermittent one. Then the codes should be cleared up and the vehicle should be taken out for a test drive until one of two things happens; the code is restored or the PCM enters readiness mode. This code might be difficult to diagnose if the PCM enters readiness mode at this point, because the code is intermittent.
• The condition which has caused the P219E code to be stored should be allowed to worsen before the right diagnosis can be made. Now if the code has been restored, then you should continue with your diagnosis. Make sure to obtain connector face views, connector pinout charts, component locator charts, wiring diagrams, and diagnostic flow charts by utilizing your source of vehicle information.
• The visual inspection of the associated wiring and connectors should be performed. The wiring which has been cut, burned, or damaged should be repaired or replaced. Now if the car engine is running smoothly and the error code P219E continues to be reset, then start the car engine and it should be allowed to reach the normal working temperature. The engine should be allowed to stay idle with the transmission in neutral or park).
• The scanner should be connected to the vehicle diagnostic port, and then carefully observe the oxygen sensor input data on the data stream. The scope of the data stream should be narrowed to include only pertinent data and you will get a faster response. If the oxygen sensors are functioning in the correct manner, then the voltage on pre-cat oxygen sensors will cycle continuously between 1 and 900-millivolts once the PCM enters closed loop operation.
• The post-cat sensors will cycle between 1 and 900-millivolts as well but they will settle at a particular point and remain relatively stable) compared to the pre-cat sensors). The oxygen sensors which would not be able to cycle adequately should be considered faulty if the car engine is in proper working order.

Common Mistakes When Diagnosing The P219E Code

• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happens when one doesn't follow all the steps carefully.
• The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek the help of experienced diagnostician to avoid any mistakes.
