[SOLVED] P1064 Code: Cylinder 4 Oil Supply Solenoid Valve Stuck – Fix It Now!

The automobile fault code P1064 indicates a problem with the Variable Valve Actuator (VVA) Solenoid.

This can cause the Engine Light to turn on or the Service Engine Soon Warning Light to illuminate. The possible causes include a faulty VVA Solenoid, an open or shorted VVA Solenoid harness, a poor electrical connection in the VVA Solenoid circuit, or a faulty Powertrain Control Module (PCM). To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0 hour.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1064 fault code.

  • The symptoms of the automobile fault code P1064 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code P1064 can be caused by a faulty Variable Valve Actuator (VVA) Solenoid, an open or shorted Variable Valve Actuator Solenoid harness, a poor electrical connection in the Variable Valve Actuator Solenoid circuit, or a faulty Powertrain Control Module (PCM).

  • The fault code P1064 can be caused by the following: 1.
  • Faulty Variable Valve Actuator (VVA) Solenoid.
  • 2.
  • Variable Valve Actuator Solenoid harness is open or shorted.
  • 3.
  • Variable Valve Actuator Solenoid circuit has a poor electrical connection.
  • 4.
  • Faulty Powertrain Control Module (PCM).

To fix fault code p1064, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P1064, 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 is estimated to take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of automobile fault code P1064 are the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P1064 fault code refers to a specific issue with the Multi-Air system in an automobile. This system controls the intake valve phase and lift, allowing for independent control of each intake valve. The Multi-Air valve train includes a hydraulic pump and a Variable Valve Actuator (VVA) Solenoid.

The VVA Solenoid is electronically controlled by the Powertrain Control Module (PCM) during the intake cam lobe event. In the case of the P1064 code, it indicates that the Cylinder 4 Oil Supply Solenoid Valve is stuck. This means that the VVA Solenoid for the fourth cylinder is not functioning properly, causing a disruption in the intake valve timing and lift.

The PCM detects this issue by monitoring the feedback current. When this fault code is triggered, it is important to address the problem with the Cylinder 4 Oil Supply Solenoid Valve.

This may involve inspecting and cleaning the solenoid valve, checking for any obstructions or damage, and ensuring proper electrical connections. If necessary, the solenoid valve may need to be replaced to resolve the issue and restore proper functioning of the Multi-Air system.

What are the possible causes of the automobile fault code P1064 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 P1064 could be the culprit. This code is often caused by a faulty Variable Valve Actuator (VVA) Solenoid, an open or shorted VVA Solenoid harness, a poor electrical connection in the VVA Solenoid circuit, or a faulty Powertrain Control Module (PCM). To visually inspect these possible causes, check the related wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins.

How does a faulty Variable Valve Actuator (VVA) Solenoid contribute to the engine light being ON and how can I check if it is the cause of the fault code P1064?

If your engine light is ON and you suspect a faulty Variable Valve Actuator (VVA) Solenoid, there are a few things you can check. First, visually inspect the wiring harness and connectors related to the VVA Solenoid. Look for any signs of damage or corrosion. Additionally, check for any broken, bent, pushed out, or corroded pins in the connectors. These issues can contribute to the engine light being ON. If you find any problems, fixing or replacing the damaged components should resolve the fault code P1064.

What steps should I take to fix the fault code P1064, including checking the wiring harness, connectors, and other components for any damage or poor electrical connections?

To fix fault code P1064, start by checking the possible causes. Visually inspect the wiring harness and connectors for any damage or poor electrical connections. Look for broken, bent, pushed out, or corroded pins on the connectors. This will help identify any issues with the Variable Valve Actuator (VVA) Solenoid or the Powertrain Control Module (PCM). Taking these steps will help resolve the problem and turn off the Engine Light or Service Engine Soon Warning Light.
