If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p3488 fault code. Here are the symptoms to look out for:

  • The P3488 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, engine stalling, rough idling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience a lack of acceleration or have difficulty starting.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P3488 fault code can be caused by various factors such as low oil pressure, restricted oil passage, and faulty cylinder deactivation solenoid.

  • The automobile fault code P3488 can be caused by low oil pressure, restricted oil passage, and engine mechanical condition.
  • It can also be caused by a faulty Cylinder Deactivation Solenoid, an open or shorted Cylinder Deactivation Solenoid harness, and poor electrical connection in the Cylinder Deactivation Solenoid circuit.

To fix the p3488 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p3488, first, check the possible causes listed above.
  • Then, 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 P3488 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosis and fixing the P3488 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P3488 code is related to the cylinder deactivation system in the engine.

The system deactivates certain cylinders to improve fuel economy under light load driving conditions. The ECM commands the deactivation of 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 P3488 code specifically indicates an issue with the exhaust valve control circuit for cylinder 11.

What are the possible causes of the P3488 automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P3488 fault code. The possible causes of this code include low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, Cylinder Deactivation Solenoid harness is open or shorted, and 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 P3488 fault code?

To fix the P3488 fault code, start by checking the possible causes listed above. Then, 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 and circuit poor electrical connection.

What are the potential consequences of ignoring the P3488 fault code?

Ignoring the P3488 fault code, which indicates low oil pressure, restricted oil passage, or faulty cylinder deactivation solenoid, can lead to serious engine damage. The engine light will remain on, indicating a problem that needs to be addressed. It is important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins to avoid further damage.

p3488 error fault code explained

If you see the Engine Light ON or Service Engine Soon Warning Light with the fault code P3488, check for low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, Cylinder Deactivation Solenoid harness, or poor electrical connection. Visually inspect the wiring harness and connectors for damage and broken pins.
