  • It is important to have the issue diagnosed and repaired promptly to avoid further damage to the vehicle.

There are several causes of the automobile fault code p246b, including fuel system and turbocharger concerns, exhaust leaks, and more.

  • The automobile fault code P246B can be caused by several factors.
  • These include fuel system concerns, issues with the turbocharger system, exhaust leaks, problems with the oxidation catalytic converter (OC), and the use of aftermarket exhaust accessories or performance modifications.
  • It is important to address these issues promptly to prevent further damage to the vehicle and ensure optimal performance.

To fix the p246b automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p246b, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P246B can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing the P246B fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P246B fault code is related to the diesel particulate filter regeneration process.

The Powertrain Control Module (PCM) monitors the conditions necessary for this process.

If the level of diesel particulate filter regeneration is not at the target reduction after 13 minutes of active regeneration, the test fails. This fault code indicates that the vehicle conditions are incorrect for diesel particulate filter regeneration. It is important to address this issue promptly to ensure proper functioning of the diesel particulate filter and avoid further damage to the vehicle.

What are the possible causes of the P246B automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P246B fault code. This code is caused by fuel system concerns, turbocharger system concern, exhaust leaks, oxidation catalytic converter (OC), or aftermarket exhaust accessories or performance modifications. To fix this issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P246B automobile fault code?

If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light due to the P246B fault code, it could be caused by fuel system concerns, turbocharger system concerns, exhaust leaks, oxidation catalytic converter (OC), or aftermarket exhaust accessories or performance modifications. To fix it, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

Is it possible for aftermarket exhaust accessories or performance modifications to cause the P246B automobile fault code?

Yes, it is possible for aftermarket exhaust accessories or performance modifications to cause the P246B automobile fault code. This code is triggered when the oxidation catalytic converter (OC) is not performing as expected. Aftermarket exhaust accessories or performance modifications can cause exhaust leaks or affect the turbocharger system, which can lead to issues with the OC. If you encounter this issue, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
