[SOLVED] P045E Code: Fix Exhaust Gas Recirculation ‘b’ Control Stuck Open!

The automobile fault code P045E indicates a problem with the EGR volume control solenoid valve.

This can cause the engine light to turn on or the service engine soon warning light to illuminate. The possible causes include an open or shorted harness, poor electrical connection, or an issue with the EGR temperature sensor and circuit.

To fix this issue, visually inspect the wiring harness and connectors for any damage.

Look for broken, bent, pushed out, or corroded pins on the connectors.

The repair time for this issue is estimated to be around 1.0. It is important to address this problem promptly to prevent further damage to the vehicle.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p045e fault code.

  • The symptoms of the automobile fault code p045e include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p045e can be caused by issues with the EGR volume control solenoid valve, its harness, circuit, and the EGR temperature sensor.

  • The fault code p045e can be caused by the following: – EGR volume control solenoid valve malfunction – Open or shorted harness of the EGR volume control solenoid valve – Poor electrical connection in the EGR volume control solenoid valve circuit – Issues with the EGR temperature sensor and its circuit.

To fix the p045e fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p045e, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix typically takes around 1.0 hour to complete.

The factors influencing the diagnosis and fixing cost of the automobile fault code p045e are the estimated repair time and the hourly rate charged by auto repair shops. The estimated repair time for this fault code is 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services. These factors will determine the overall cost of diagnosing and fixing the p045e fault code.

The P045E fault code refers to a problem with the control of the Exhaust Gas Recirculation (EGR) system.

This code specifically indicates that the ‘B’ control of the EGR system is stuck open. The EGR system is responsible for recirculating a portion of the exhaust gases back into the engine, which helps reduce emissions.

In newer vehicles, a step motor is used to control the flow rate of the EGR system. The EGR valve opens and closes based on the pulse signals from the Engine Control Module (ECM).

However, in the case of the P045E code, the ‘B’ control of the EGR system is stuck open, meaning it is not closing properly.

This can lead to issues with engine performance and increased emissions. It is important to have this issue addressed and repaired to ensure proper functioning of the EGR system and to meet emission standards.

What are the possible causes for the automobile fault code p045e and how can I visually inspect them?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P045E could be the culprit. This code is often caused by issues with the EGR volume control solenoid valve, its harness, or the electrical connection. To visually inspect these potential causes, check the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins on the connectors. By conducting this inspection, you’ll be one step closer to resolving the issue.

How can I determine if the EGR volume control solenoid valve harness is open or shorted and what should I do if it is?

If you’re experiencing the symptom of the Engine Light being ON or the Service Engine Soon Warning Light, it could be due to a problem with the EGR volume control solenoid valve. To determine if the issue lies with the EGR volume control solenoid valve harness being open or shorted, you should visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This will help you identify the cause of the problem and take appropriate action to fix it.

What steps should I take to check the EGR temperature sensor and circuit for any issues and how can I identify damaged components or corroded connector pins?

To check the EGR temperature sensor and circuit for any issues, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. These issues can cause the Engine Light to turn on. By checking and addressing these possible causes, you can fix the problem and ensure the smooth functioning of your vehicle.
