If you’re experiencing an illuminated engine light or service engine soon warning light, read on to learn about the symptoms of the p24b1 automobile fault code.

  • The P24B1 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include reduced engine power, decreased fuel efficiency, rough idling, and difficulty starting the engine.
  • Additionally, the vehicle may emit black smoke from the exhaust, and there may be a noticeable decrease in acceleration.
  • If you experience any of these symptoms, it is important to have your vehicle diagnosed and repaired by a qualified mechanic as soon as possible.

The P24B1 fault code can be caused by a faulty sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P24B1 can be caused by a faulty exhaust particulate matter sensor.
  • It can also be caused by an open or shorted exhaust particulate matter sensor harness.
  • Additionally, a poor electrical connection in the exhaust particulate matter sensor circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p24b1, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p24b1, 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 fault code P24B1 indicates an issue with the exhaust gas temperature sensor circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P24B1 fault code is related to the Particulate Matter (PM) sensor in diesel engines.

The PM sensor monitors the amount of soot in the exhaust gas. The sensor has a ceramic element with comb-shaped Interdigital Electrodes (IDE), a heater, and a positive temperature coefficient resistor for temperature measurement.

The sensor generates a current when a conductive path is formed due to the soot absorbed in the combs between the electrodes. The sensor performs a regeneration to clean off the soot before the measurement phase begins. The P24B1 code is set when the sensor control unit detects an internal fault of the sensor, fault of the sensor circuitry, or low voltage on the sensor supply circuit.

What are the possible causes of the automobile fault code P24B1?

If you see the engine light on or the service engine soon warning light, it could be due to the P24B1 fault code. This code is usually caused by a faulty exhaust particulate matter sensor, an open or shorted sensor 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 pins.

How can one visually inspect the related wiring harness and connectors to fix the P24B1 fault code?

If you’re experiencing the P24B1 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Exhaust Particulate Matter Sensor, an open or shorted harness, or a poor electrical connection. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues and determine the best course of action to resolve the problem.

What are the consequences of ignoring the P24B1 fault code and not fixing it in time?

Ignoring the P24B1 fault code, caused by a faulty exhaust particulate matter sensor or related wiring issues, can lead to serious consequences. The engine light or service engine soon warning light will remain on, indicating a problem with the vehicle’s emissions system. This can result in decreased fuel efficiency, increased emissions, and potential damage to the engine and exhaust system. It is important to address the issue promptly by visually inspecting the wiring harness and connectors and checking for damaged components.
