[SOLVED] P1035 Code: Fix Cylinder 1 Oil Supply Solenoid Valve Open Circuit!

The automobile fault code P1035 indicates a problem with the Variable Valve Actuator (VVA) Solenoid.

The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light. The cause could be a faulty VVA Solenoid, an open or shorted harness, a poor electrical connection, 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.

It is important to address this problem promptly to prevent further damage to the engine.

  • The fault code P1035 can be caused by a faulty Variable Valve Actuator (VVA) Solenoid.
  • It can also be caused by an open or shorted harness of the Variable Valve Actuator Solenoid.
  • Another possible cause is a poor electrical connection in the Variable Valve Actuator Solenoid circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also trigger this fault code.

To fix the automobile fault code p1035, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1035, 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 if there are any broken, bent, pushed out, or corroded pins in the connectors.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1035 are the estimated repair time of 1.0 hour and the typical auto repair shop charges of $75 to $150 per hour.

The P1035 fault code refers to an issue with the Cylinder 1 Oil Supply Solenoid Valve Driver. This valve is part of the Multi-Air system, which controls the intake valves in a more precise and independent manner.

The Multi-Air system uses an electronically controlled hydraulic link between the camshaft and intake valve.

The oil supply solenoid valve driver is responsible for controlling the oil pressure to the valve, which in turn determines the timing and lift of the intake valve. When the Powertrain Control Module (PCM) detects an open circuit condition for the oil supply solenoid valve driver, it will trigger the P1035 fault code. This means that there is a problem with the electrical connection or the solenoid itself, preventing proper control of the intake valve timing and lift.

If you encounter this fault code, it is important to have the electrical connections and solenoid checked and repaired if necessary. This will ensure that the Multi-Air system functions properly, allowing for optimal engine performance and fuel efficiency.

What are the possible causes for the automobile fault code P1035 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 P1035 might be the culprit. This code can be 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 even 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. Don’t forget to examine the components as well.

How can a faulty Variable Valve Actuator (VVA) Solenoid be identified as the cause of the engine light being ON?

If you notice that your engine light is ON or you see the Service Engine Soon Warning Light, a possible cause could be a faulty Variable Valve Actuator (VVA) Solenoid. To confirm this, you can visually inspect the wiring harness and connectors related to the VVA Solenoid. Look out for any damaged components or broken, bent, pushed out, or corroded connector pins. If you find any issues, it’s recommended to fix or replace them accordingly. Additionally, it’s also worth checking for an open or shorted VVA Solenoid harness and ensuring a good electrical connection. If the problem persists, it might be necessary to have the Powertrain Control Module (PCM) checked for faults.

What steps can be taken to fix the P1035 fault code and ensure a proper electrical connection for the Variable Valve Actuator Solenoid?

To fix the P1035 fault code and ensure a proper electrical connection for the Variable Valve Actuator Solenoid, start by checking the possible causes mentioned above. Then, visually inspect the wiring harness and connectors related to the solenoid. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Taking these steps will help identify and address any issues with the electrical connection, ensuring the proper functioning of the Variable Valve Actuator Solenoid.
