The P24A1 automobile fault code is a common issue that triggers the Engine Light ON or Service Engine Soon Warning Light. It can be caused by a faulty Exhaust Gas Temperature Sensor, an open or shorted Exhaust Gas Temperature Sensor harness, or a faulty Exhaust Particulate Filter. To fix the issue, one needs to perform the Diesel Particulate Filter Service Regeneration and visually inspect the related wiring harness and connectors.

The repair time for this issue is estimated to be around 1.0 hour.

It is important to address this issue promptly to avoid further damage to the vehicle’s engine.

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the p24a1 fault code. Here are the symptoms to look out for:

  • The P24A1 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The P24A1 automobile fault code can be caused by a range of issues, including faulty sensors and filters.

  • The automobile fault code P24A1 can be caused by several factors.
  • These include a need to perform the Diesel Particulate Filter Service Regeneration, a faulty Exhaust Gas Temperature Sensor, an open or shorted Exhaust Gas Temperature Sensor harness, a poor electrical connection in the Exhaust Gas Temperature Sensor circuit, and a faulty Exhaust Particulate Filter.
  • It is important to address all of these potential causes in order to effectively diagnose and fix the issue.

Below are the possible fixes for the automobile fault code p24a1, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code p24a1, 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 P24A1 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 P24A1 code is related to the diesel exhaust aftertreatment system. The system includes a pre-catalytic converter and a Diesel Particulate Filter (DPF).

The DPF collects particulates from the engine exhaust to prevent soot discharge.

The Engine Control Module (ECM) commands DPF regeneration to prevent clogging. The DTC is set when the ECM detects high exhaust temperature during DPF regeneration.

What is the possible cause of the P24A1 fault code?

If you’re experiencing the P24A1 fault code, your engine light may be on. This could be due to a faulty exhaust gas temperature sensor, a poor electrical connection in the exhaust gas temperature sensor circuit, or a faulty exhaust particulate filter. To fix the 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 P24A1 fault code?

If you’re experiencing the P24A1 fault code, indicated by the engine light or service engine soon warning light, it could be due to a faulty exhaust gas temperature sensor, a faulty exhaust particulate filter, or a poor electrical connection in the exhaust gas temperature sensor circuit. To fix the issue, perform a diesel particulate filter service regeneration and visually inspect the related wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector pins.

What should I visually inspect to troubleshoot the P24A1 fault code?

If you’re troubleshooting the P24A1 fault code, start by checking for an illuminated engine light or service engine soon warning light. The possible causes include a faulty exhaust gas temperature sensor, a faulty exhaust particulate filter, or an open or shorted exhaust gas temperature sensor harness. To fix the issue, visually inspect the related wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector pins.

p24a1 error fault code explained

If you see the Engine Light ON or Service Engine Soon Warning Light due to p24a1, perform the Diesel Particulate Filter Service Regeneration.

Check for faulty Exhaust Gas Temperature Sensor, open or shorted Exhaust Gas Temperature Sensor harness, poor electrical connection in Exhaust Gas Temperature Sensor circuit, or faulty Exhaust Particulate Filter. Visually inspect the related wiring harness and connectors, and check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
