If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P245A fault code. This code indicates a problem with the Exhaust Gas Recirculation (EGR) Cooler Bypass Valve. The possible causes include a faulty valve, open or shorted harness, poor electrical connection, or a faulty Engine Control Module (ECM).

The repair importance is high as it can affect the engine’s performance and fuel efficiency.

The repair difficulty is moderate, and it takes around 1.0 hour to fix.

To interpret the fault code, you need to check the possible causes and visually inspect the related wiring harness and connectors.

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 p245a fault code. Here are the symptoms to look out for:

  • The P245A fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, decreased fuel efficiency, reduced engine power, difficulty starting the engine, rough idling, and increased emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p245a can be caused by a faulty EGR cooler bypass valve, open or shorted harness, poor electrical connection, or a faulty ECM.

  • The automobile fault code P245A can be caused by a faulty Exhaust Gas Recirculation (EGR) Cooler Bypass Valve.
  • It can also be caused by an open or shorted Exhaust Gas Recirculation Cooler Bypass Valve harness.
  • Another cause can be a poor electrical connection in the Exhaust Gas Recirculation Cooler Bypass Valve circuit.
  • Lastly, a faulty Engine Control Module (ECM) can also cause this fault code.

Below are some possible fixes for the automobile fault code p245a, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p245a, 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 P245A indicates a problem with the diesel particulate filter pressure sensor circuit. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this issue varies 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 problem, the type of vehicle, and the location of the repair shop.

The P245A code is related to the Exhaust Gas Recirculation (EGR) cooler bypass control circuit. The Engine Control Module (ECM) uses the EGR bypass valve position sensor to determine the position of the bypass valve.

The ECM sends a reference voltage through the 5-volt reference circuit to the position sensor.

The ECM compares the actual bypass valve position with the desired bypass valve position when the valve is commanded open or closed. The DTC will be set when the ECM detects an open circuit condition of the EGR cooler bypass valve control circuit for greater than 3 s.

What are the possible causes of the automobile fault code P245A?

If you see the engine light on or service engine soon warning light, it could be due to the P245A fault code. This code is caused by a faulty Exhaust Gas Recirculation (EGR) Cooler Bypass Valve, an open or shorted EGR Cooler Bypass Valve harness, a poor electrical connection in the EGR Cooler Bypass Valve circuit, or a faulty Engine Control Module (ECM). 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.

How can I visually inspect the related wiring harness and connectors for the P245A fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P245A fault code, you may need 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. This could be caused by a faulty Exhaust Gas Recirculation (EGR) Cooler Bypass Valve, an open or shorted EGR Cooler Bypass Valve harness, a poor electrical connection in the EGR Cooler Bypass Valve circuit, or a faulty Engine Control Module (ECM). Check the “Possible Causes” listed above for more information.

Is it necessary to replace the Exhaust Gas Recirculation Cooler Bypass Valve for fixing the P245A fault code?

It is not necessary to replace the Exhaust Gas Recirculation Cooler Bypass Valve for fixing the P245A fault code. The fault code can be caused by a faulty valve, open or shorted harness, poor electrical connection, or a faulty Engine Control Module. To fix the issue, one 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.

p245a error fault code explained

If your engine light is on and you have a P245A fault code, it may be due to a faulty EGR cooler bypass valve, open or shorted harness, poor electrical connection, or a faulty ECM. Visually inspect the wiring harness and connectors for damage and check for broken or corroded pins.
