The P246D automobile fault code indicates a problem with the Diesel Particulate Filter Pressure Sensor. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this issue could be a faulty sensor, an open or shorted harness, or a poor electrical connection. It is important to address this issue promptly as it can lead to reduced engine performance and increased emissions. The repair process involves visually inspecting the wiring harness and connectors for any damage or corrosion.

The difficulty level of this repair is considered to be moderate, with an estimated repair time of 1.0 hour.

To interpret the fault code, it is recommended to check the “Possible Causes” listed above and visually inspect the related components.

Repair Importance Level6.67 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p246d fault code. Here are the symptoms to look out for:

  • The P246D fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience increased emissions, reduced acceleration, and a rough idle.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P246D automobile fault code can be caused by a faulty sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P246D can be caused by a faulty Diesel Particulate Filter Pressure Sensor.
  • It can also be caused by an open or shorted Diesel Particulate Filter Pressure Sensor harness.
  • Additionally, a poor electrical connection in the Diesel Particulate Filter Pressure Sensor circuit can also trigger this fault code.

To fix the p246d automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p246d, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for 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 P246D can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P246D fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time.

The P246D fault code is related to the Diesel Particulate Filter (DPF) pressure sensor. The Powertrain Control Module (PCM) monitors the sensor’s signal value during idle and part load operating conditions. The test fails when the sensor’s signal value at idle is less than 0.15 kPa (0.022 psi) or when it’s less than a minimum value or greater than a maximum value at part load.

The minimum and maximum values are based on the volume of exhaust. The fault code indicates a correlation issue between the pressure sensors ‘A’ and ‘B’.

What are the possible causes of the P246D automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P246D fault code. This code is usually caused by a faulty diesel particulate filter pressure sensor, an open or shorted harness, or a poor electrical connection in the sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P246D fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P246D fault code, there are a few things you can do to fix it. First, check for a faulty Diesel Particulate Filter Pressure Sensor or an open or shorted harness. If those aren’t the issue, visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you identify and fix the problem.

What are the consequences of ignoring the P246D fault code?

Ignoring the P246D fault code, which indicates a faulty Diesel Particulate Filter Pressure Sensor, can lead to serious consequences. The engine light will remain on, and the vehicle may experience reduced power and fuel efficiency. Additionally, the diesel particulate filter may become clogged, leading to increased emissions and potential damage to the engine. It is important to address the issue promptly by visually inspecting the wiring harness and connectors and checking for damaged components.
