[SOLVED] P3453 Code: Fixing Cylinder 7 Exhaust Valve Control Circuit/Open

The P3453 fault code in automobiles indicates a problem with the Cylinder Deactivation System.

The symptom is an illuminated Engine Light or Service Engine Soon Warning Light.

The cause could be low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, or poor electrical connection.

The repair importance is high as it affects the engine’s performance and fuel efficiency. 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 1.0 hour.

To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related components.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p3453 fault code.

Here are the symptoms to look out for:

  • The P3453 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, rough engine idle, decreased fuel efficiency, engine misfires, and engine hesitation during acceleration.
  • It can also cause the engine to stall or shut off completely.
  • These symptoms can be caused by a faulty exhaust valve control solenoid or a damaged wiring harness.
  • It is important to address these symptoms promptly to prevent further damage to the engine and ensure safe driving conditions.

The P3453 fault code in automobiles can be caused by a range of factors, including low oil pressure and faulty solenoids.

  • The automobile fault code P3453 can be caused by low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, Cylinder Deactivation Solenoid harness being open or shorted, and Cylinder Deactivation Solenoid circuit having poor electrical connection.

Below are the possible fixes for the automobile fault code p3453, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p3453, 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 P3453 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 P3453 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P3453 code refers to the cylinder deactivation system in the engine. The system deactivates cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank, switching to a V4 mode. Cylinder deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders by using special valve lifters.

The deactivation lifters contain spring-loaded locking pins that connect the internal pin housing of the lifter to the outer housing. Switching between V8 and V4 mode is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator. The 250 milliseconds includes the time for the ECM to sequence the transitions, the response time for the VLOM solenoids to energize, and the time for the valve lifters to deactivate, all within 2 revolutions of the engine crankshaft.

What are the possible causes of the P3453 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P3453 fault code. This code is caused by low oil pressure, restricted oil passage, engine mechanical condition, faulty cylinder deactivation solenoid, cylinder deactivation solenoid harness being open or shorted, or cylinder deactivation solenoid circuit poor electrical connection. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P3453 fault code?

If you’re experiencing the P3453 fault code, start by checking the possible causes listed above. To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues with the Cylinder Deactivation Solenoid harness, which could be open or shorted, or have a poor electrical connection. Once you’ve identified the issue, you can take the necessary steps to fix it.

What are the consequences of ignoring the P3453 fault code?

Ignoring the P3453 fault code, which indicates a problem with the Cylinder Deactivation Solenoid, can lead to serious consequences. The engine light will remain on, indicating a problem with the engine. The cause of the problem could be low oil pressure, restricted oil passage, engine mechanical condition, or a faulty Cylinder Deactivation Solenoid. To fix the issue, it is important 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.

p3453 error fault code explained

If you see the Engine Light ON or Service Engine Soon Warning Light with the fault code p3453, check for low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, Cylinder Deactivation Solenoid harness, or poor electrical connection.
