P246C OBD Error Code: Problem & Solutions

<<See All OBD Codes

Stressed? Tired of seeing the check engine light flashing? No worries, Parts Avatar has a solution for all your problems! Here’s all that you need to know about the error code P246C. This generic OBD-II code decreased engine performance is also known as a diesel particulate filter restriction - forced limited power. While converting the leftover exhaust particles to nontoxic gases, the diesel exhaust fluid is employed. The temperature in the exhaust system should be risen, in order to burn off the particles. This temperature in diesel particulate filter (DPF) is obtained by injecting DEF fluid into the exhaust stream. Then the system performs the function of converting the NOx to nitrogen, carbon dioxide and water. Also, to reduce the NOx in the exhaust stream, the reductant catalyst (SRC) is added. The exhaust pressure before and after the diesel particulate filter (DPF) is monitored by the engine computer (PCM). If you observe extreme high pressure on the inlet side, a restriction in the DPF should be suspected. The code P246C is stored by the powertrain control module. The powertrain control module at times, may limit the power available from the engine to avoid any damage to the additional components.

To avoid any discrepancies (such as conditions where it may be overloaded) the diesel particulate filter (DPF) is monitored. The calculated restrictions of the DPF to the two thresholds is compared by the monitor. The wrench light illuminates, after exceeding the first threshold for a sufficient period of time. Both malfunction indicator light and wrench light illuminate when the second threshold exceeds a sufficient period of time. The engine output gets limited and the EGR illuminates too.

What causes this problem with the Diesel Particulate Filter Restriction - Forced Limited Power?

• A damaged diesel particulate filter

1. Diesel Particulate Filter - An increased idle speed? Or are you facing some intermittent starting issues? If yes, then it signals at a faulty diesel particulate filter. So it is very important to replace the malfunctioning diesel particulate filter with us at equitable prices.
2. Powertrain Control Module - This is regarded as the brain of the system. So if you want to prevent the situation from getting worse get your engine computer mended or restored now!
3. Carburetor - Having problems with the carburetor? Backfiring or overheating? Don’t you worry, Parts Avatar has it all. A faulty carburetor could end up being the root cause behind the error code P246C.
4. Exhaust Gas Recirculation - A lot of problems can arise due to a damaged exhaust gas recirculation. Major problems include a diminishing engine performance. Tune into Parts Avatar for your new EGR.
5. Distributor Cap - Excessive or unusual engine noises? Yes, it is due to your broken or defective distributor cap. Change or repair or now in order to get rid of all large number of problems.
6. Camshaft - Get your error code P246C fixed instantly with a new camshaft. It is likely to create problems like engine stalling and rough idle. Parts Avatar is just the right place that provides the best camshaft across the country.
7. Spark Plug - Weary and damage spark plugs can often be problematic. So to add some spark to your ride you definitely need the perfect quality spark plugs offered at Parts Avatar. Isn’t that just the perfect deal?

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 P246C here:

Common Symptoms

• Reduced engine performance
• Black smoke emissions
• Lack of power

Here are some ways with the help of which you will be able to correct the OBD code P246C:

• Repair or replace a defective/clogged diesel particulate filter
• Make sure all the electrical components in the system that are damaged are mended or restored immediately

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade diesel particulate filter, PCM, carburetor, EGR, distributor cap, camshaft, spark plug and a lot more for our precious customers.

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

If the code P246C is stored, you are likely to hear loud noises and explosions from the rear of the vehicle upon acceleration. Check the carburetor to make sure that the fuel and the air combination are balanced appropriately. Perform a thorough inspection of the distributor cap for any cracks or hairline splits as this can produce a backfire if the settings fail to match the specifications. Then proceed further to check the spark plugs to ensure that they are neat and undamaged. Next, the engine gaskets should be inspected for any traces of damage (as they are responsible for maintaining correct gas exchange within the engine. The OBD-II code P246C refers to the camshaft (cam) timing. In such cases where the cam timing is over-retarded, one likely to observe an illuminated engine light with the code being stored.

Common Mistakes When Diagnosing the P246C Code

Here we have listed a few common mistakes that should be prevented in order to perform a successful diagnosis:

• A malfunctioning diesel particulate filter (DPF)
• You must complete the Manual DPF regeneration
• A failure in the powertrain control module (PCM)
• Update the powertrain control module (PCM) software
