[SOLVED] P245D Code: High Voltage Egr Cooler Bypass – How To Fix

The P245D automobile fault code indicates a problem with the Exhaust Gas Recirculation (EGR) Cooler Bypass Valve. The most common symptom is the Engine Light ON or Service Engine Soon Warning Light. The cause of this issue could be a faulty EGR Cooler Bypass Valve, an open or shorted harness, poor electrical connection, or a faulty Engine Control Module (ECM).

The importance of repairing this issue lies in the fact that it can lead to reduced engine performance and increased emissions. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

The repair time is estimated to be around 1.0 hour. It is essential to interpret the fault code correctly to identify the root cause of the problem and fix it effectively.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p245d fault code.

Here are the symptoms to look out for:

  • The P245D 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 p245d 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 P245D 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 p245d, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p245d, 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 P245D 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 fixing the P245D fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P245D 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 that the EGR cooler bypass valve control circuits are shorted to voltage for greater than 3 s.

What are the possible causes of the automobile fault code P245D?

If you see the engine light on or service engine soon warning light, it could be due to the P245D fault code. This code is usually 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 P245D fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P245D 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).

Is it necessary to replace the Exhaust Gas Recirculation Cooler Bypass Valve for fixing the P245D fault code?

It is recommended to visually inspect the related wiring harness and connectors, and check for damaged components before replacing the Exhaust Gas Recirculation Cooler Bypass Valve for fixing the P245D fault code. The fault code can also be caused by a faulty EGR Cooler Bypass Valve harness, open or shorted circuit, or a faulty Engine Control Module (ECM).
