Error Code P219D: What It Means & What To Do?

<<See All OBD Codes

The trouble code P219D can be elucidated as Cylinder #2 Imbalance Error. To check the air to fuel ratio for each cylinder of the car engine, the powertrain control module would utilize the input from heated exhaust oxygen sensors which are also known as air fuel sensors and crankshaft position (CKP) and camshaft position (CMP) sensors.

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. The cylinder 2 is being monitored by the engine control module. This trouble code would be set by the ECM when an imbalance error in the number two cylinder would be detected by the engine control module.

What causes this problem with the Cylinder #2 Imbalance Error?

• Poor engine compression
• Some issues related to the oxygen sensor/s
• There can be distorted wiring and/or connectors
• The CKP or CMP sensor might not be functioning properly
• The mass air flow or manifold air pressure sensor might be damaged

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times, a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Oxygen Sensor - Oxygen sensor plays a vital role in anticipating the levels of oxygen measured for the optimal air to fuel ratios for the combustion process and also for the exhaust emissions to keep the emission levels under check. Thus, replace faulty oxygen sensor now!
3. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
4. Mass Air Flow Sensor - A faulty mass airflow sensor will cause problems similar to low compression or low vacuum, and will also show symptoms similar to when your vehicle has low fuel pressure from a faulty fuel pump. Thus, replace damaged/faulty MAF sensor today!
5. Fuel Pump - If the fuel pump is damaged, it can cause engine to sputter at high speeds and sometimes may not even start. Loss of power during acceleration, rising engine temperatures and problematic throttle response are other major problems too. Replace faulty pump today!
6. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?
7. Fuel Injector - The fuel injectors are an important component of the fuel delivery system that helps in proper utilization of the fuel entering the engine. This not only helps in taking care of the air to fuel ratios in the engine, helping the combustion process but also enhances the performance. Thus, replace faulty injector now!

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

• The technician should start by addressing 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 P219D being stored. In order to correctly diagnose the code P219D, 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 P219D 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 P219D 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 P219D 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.
