Error Code P246B: What It Means & What To Do?

OBD Code P246B - Vehicle Conditions Incorrect for Diesel Particulate Filter Regeneration

<<See All OBD Codes

Wondering on how are you going to start the diagnosis procedure? Don’t worry, just join Parts Avatar in this journey of diagnosing and treating the error code P246B. The conditions essential for the diesel particulate filter regeneration is continuously monitored by the powertrain control module (PCM). It is advised to be careful while performing the test as it tends to fail if the level of the diesel particulate regeneration is not at the target reduction even after 13 minutes of active regeneration.

It is notable that in order to convert the remaining exhaust particles to nontoxic gases, the diesel exhaust fluid is utilized. An increased temperature is required in the exhaust system to completely burn off the particles. An injection of the DEF into the exhaust stream is required to attain the desired temperature in the diesel particulate filter (DPF). Only then the system is able to alter the NOx into nitrogen, carbon dioxide and water. To further decrease the NOx present in the exhaust system, the reductant catalyst (SRC) is added on. To clean itself, the filter is required to go into the “regeneration mode”. This happens only after certain driving conditions are set. The code P246B is set by the engine control module (ECM), when the filter gets too full. Also, at times, the vehicle enters the “limp home mode” thereby limiting the engine power available and the speed at which the vehicle is driven.

 

What causes this problem with the Vehicle Conditions Incorrect for Diesel Particulate Filter Regeneration?

 

  • Problems associated to the fuel system
  • Malfunctioning parts in the turbocharger system
  • Exhaust leakages
  • A fault in the oxidation catalytic converter (OC)
  • The aftermarket exhaust accessories or performance alterations

Replace/Repair These Parts To Fix OBD Code P246B

  1. Diesel particulate filter - Is you diesel particulate filter contaminated? Perform a thorough cleansing or replace it as soon as possible if you wish to see the error code P246B disappear.
  2. Powertrain control module - Abbreviated as PCM; if faulty this can cause a lot of problems. A faulty one leads to downward emissions along with other issues like a sluggish engine crank, failure in the emission system etc. We advise you to get your faulty PCM changed now by simply logging into Parts Avatar.
  3. Turbocharger - An unsound turbocharger can end up being the chief host inviting the error code P246B. So replacing one can be one of the wisest decisions to avoid a problematic system.
  4. 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.
  5. Diesel exhaust fluid pump - Observing a loss of efficiency due to a faulty DEF pump? Yes, it is likely to lead to complications in the operations of the system. It is advised that you get it changed right away.
  6. Exhaust system parts - Is black smoke emitting out from the system? Poor fuel economy? Engine overheating? All this happens due to a malfunctioning exhaust system parts. Tune into Parts Avatar, your one stop destination for best products and services!
  7. Fuel system parts - A lot of issues can arise due to a defective fuel system parts 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 P246B.
  8. Thermostat - Coolant leaks, temperature gauge reading very high? All this is likely to follow a malfunctioning thermostat. Change or repair now!

Easy Diagnosis Of Engine Error OBD Code P246B

Want to diagnose the error code P246B? Well, then you should follow these steps in order to diagnose this fault code:

 

An advanced OBD-II trouble code scanner should be applied to diagnose this trouble code P246B. The scanner should be used to check and view the freeze frame data and assess the code by a qualified mechanic. The mechanic should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be test driven to see if the code persists. If the code vanishes it could likely be due to a malfunctioning diagnose or may display an intermittent issue.

 

Common Mistakes When Diagnosing The P246B Code

 

Here we have listed a few common mistakes that should be avoided while performing the procedure:

 

  • A fault in the diesel particulate filter (DPF)
  • Manual DPF regeneration should be complete
  • A defective powertrain control module (PCM)
  • A software update in the powertrain control module (PCM)
  • A possible defect in the thermostat
