Guide To P200F OBD Error Code Solutions

<<See All OBD Codes

Error code P200F? Don’t know where to start from? No worries, Parts Avatar is here to help you! Here’ how you can solve the error code P200F. This generic OBD-II code decreased engine performance is also known as a catalyst system over temperature. The catalytic converter performs the task of converting the exhaust gases left over by the combustion process to nontoxic emissions. Then the engine control module (ECM) parallels the front and rear oxygen sensors to each other to determine catalytic converter adequacy.

It should be noted that, the PCM stores the code P200F, if the intake from the rear oxygen sensor starts to collate the front oxygen sensor. One can observe that the catalytic converters are wrapped under federally mandated 8yr/80,000-mile warranty by the vehicle's manufacturer. Usually, the catalytic converters collapse as a result of something else (engine misfires, internal oil leak, or internal coolant leak) not being mended or restored. Also, most of times, the primary cause of the failure is usually not covered under warranty.

What causes this problem with the Catalyst System Over Temperature Bank 2

• A malfunction in the SCR system
• A fault in the SCR injector
• Deficient or dirty DEF fluid
• Distorted exhaust temperature sensor
• A damaged SCR controller or programming error
• Leakage in the pre-catalyst exhaust
• Wrong installation of aftermarket or high-performance exhaust components

1. Catalytic converter - Engine misfires, loss of power while accelerating and degraded performance are likely to follow after a catalytic converter malfunctions. We recommend you to repair or replace as soon as possible.
2. Powertrain control module - Do you have any idea about the extent to which a faulty powertrain control module can harm your system? A faulty powertrain control module brings along issues like a malfunction in the functioning of the entire engine, also the sparks and ignition timing from the spark plugs are controlled and received by the PCM. Tune into Parts Avatar if you want to get your error code fixed.
3. Oxygen sensor - A lot of issues can arise due to a defective oxygen sensor including rough idle, poor engine performance, hesitation and stalling. A damaged one should be changed or repaired immediately if you want to get rid of the error code P200F.
4. Diesel exhaust fluid pump - Do you know that a faulty diesel exhaust fluid pump can of problems like potential damage to components, including DEF dosing pump and diesel particulate filter and malfunctions with the machine’s SCR system. Parts Avatar is just the right place that provides superior quality diesel exhaust fluid pump across the country.
5. Exhaust gas temperature sensor - Engine overheating? Check engine light flashing on? Fall in the fuel economy? Yes, all this is likely to follow a defective exhaust temperature sensor. Tune into Parts Avatar for your new exhaust temperature sensor offered at just the right prices.
6. Exhaust system parts - Error code P200F? Don’t know the reason behind it? Well, it is often triggered due defective exhaust system parts. Apart from this problems with the fuel efficiency, loss of power and no acceleration can be observed too. Mend or restore your exhaust system parts now! Tune into Parts Avatar for you brand new exhaust system partsavailable at budget friendly prices.

It is vital 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 P200F here:

Common Symptoms

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P200F code to be stored:

Firstly, if there are SCR codes stored, they should be attended before making an effort to diagnose the stored P200F. Before attempting a diagnosis for this type of code, the pre-catalyst exhaust leaks should be fixed. For this purpose, all that is required is a diagnostic scanner, a digital volt/ohmmeter (DVOM), an infrared thermometer with a laser pointer, and a source of vehicle specific diagnostic information to diagnose the code P200F. Locate a technical service bulletin (TSB) that parallels the vehicle year, make/model as well as the engine size, code/s stored, and symptoms displayed. This really helps in acquiring important diagnostic information.

Start the diagnosis with a thorough visual inspection of the SCR injection system, exhaust temperature sensors, NOx sensors, and oxygen (02) sensor harnesses and connectors. It is essential to repair or replace all the corroded or damaged wiring and connectors. Connect the scanner to the vehicle diagnostic connector to restore all stored codes and all the relevant freeze frame data. It is advised to register this information down before the codes are cleared. Test drive the vehicle till the PCM either enters readiness mode or the code reappears. The code is an intermittent one (and will be quite challenging) if the PCM enters readiness mode.

In such a case, the conditions that added to the code being stored may need to worsen before a correct diagnosis can actually be made. If the code be reappears, look out for source of vehicle information to obtain diagnostic flow charts, connector pin out charts, connector face views along with the component testing procedures and specifications. It should be noted that this information is required to execute the next step of your diagnosis. Next, utilize the infrared thermometer to gather actual pre and post catalyst temperatures. The scanner data stream should be observed to compare the actual findings with the information found on the scanner data display screen. Also collate the exhaust temperature sensor data between engine banks. If in case any discrepancies in the exhaust temperature are found, test the respective sensor/s using the DVOM. Sensors installed that fail to parallel manufacturer specifications, should be considered defective. If all sensors and circuitry appear to be functioning according to the manufacturer’ specifications, suspect that the catalyst element is malfunctioning or that the SCR system is inoperative. Lastly, ensure that the DEF reservoir is full of the appropriate fluid and the SCR system is functioning as per the requirements.

Common Mistakes When Diagnosing the P200F Code

Here we have listed a few common mistakes that should be avoided while diagnosing the error code P200F:

• A failed catalytic converter
• A faulty oxygen sensor
