If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p3452 fault code.

Here are the symptoms to look out for:

  • The P3452 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON, rough engine idle, engine misfire, decreased fuel efficiency, and reduced engine power.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P3452 automobile fault code can be caused by various factors, including low oil pressure and faulty valve lifter oil manifold assembly.

  • The automobile fault code P3452 can be caused by low oil pressure.
  • It can also be caused by a restricted oil passage.
  • Another cause of this fault code is a faulty Valve Lifter Oil Manifold Assembly.
  • An open or shorted Valve Lifter Oil Manifold Assembly harness can also trigger this code.
  • A poor electrical connection in the Valve Lifter Oil Manifold Assembly circuit can also be a cause.
  • Lastly, a faulty Engine Control Module (ECM) can also be a reason for the P3452 fault code.

To fix the p3452 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p3452, you need to check the possible causes listed above.
  • 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 fix will take an estimated repair time of 1.0 hour.

The automobile fault code P3452 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 P3452 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P3452 code refers to the cylinder deactivation system in the engine. The Engine Control Module (ECM) commands the cylinder deactivation system ON to deactivate engine cylinders 1, 7, 6, and 4, 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 modes is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator.

What are the possible causes of the P3452 automobile fault code?

If you’re experiencing the P3452 fault code, your engine light may be on. This could be due to low oil pressure, a restricted oil passage, a faulty valve lifter oil manifold assembly, or a poor electrical connection in the valve lifter oil manifold assembly circuit. 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 P3452 automobile fault code?

If you’re experiencing the P3452 fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few possible causes to consider. These include low oil pressure, a restricted oil passage, a faulty valve lifter oil manifold assembly, an open or shorted valve lifter oil manifold assembly harness, a poor electrical connection in the valve lifter oil manifold assembly circuit, or a faulty engine control module (ECM). To fix the issue, start by checking the possible causes listed above and visually inspecting the related wiring harness and connectors for any damage or corrosion.

What should I visually inspect to troubleshoot the P3452 automobile fault code?

If you’re troubleshooting the P3452 automobile fault code, start by checking for the symptom of the engine light being on. The cause could be low oil pressure, a restricted oil passage, a faulty valve lifter oil manifold assembly, an open or shorted harness, a poor electrical connection, or a faulty engine control module. To fix the issue, visually inspect the related wiring harness and connectors, checking for damaged components and broken, bent, pushed out, or corroded connector pins.

p3452 error fault code explained

If you see the Engine Light ON (or Service Engine Soon Warning Light) due to the p3452 fault code, check for low oil pressure, restricted oil passage, faulty Valve Lifter Oil Manifold Assembly, or a faulty Engine Control Module (ECM).

Visually inspect the related wiring harness and connectors for any damage or corrosion.
