This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble understanding a message from the engine about how it should adjust the valves.
This code indicates a problem with the communication between the Variable Valve Lift (VVL) system and the car's main computer. The message being sent is not what the computer expects.
The P1035 code is triggered when the Engine Control Module (ECM) detects an incorrect or unexpected CAN (Controller Area Network) message from the Variable Valve Lift (VVL) system for Bank 1. This could be due to a fault in the VVL system, wiring issues, or a malfunctioning ECM.
• Check Engine Light is on
• Poor engine performance
• Reduced fuel efficiency
• Faulty VVL actuator
• Wiring issues in the CAN bus
• Malfunctioning ECM
VVL: Variable Valve Lift, a system that adjusts the lift of the engine's valves for better performance.
CAN: Controller Area Network, a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other.
• Use an OBD-II scanner to confirm the code.
• Inspect the VVL actuator and wiring for damage.
• Test the ECM for proper functionality.
• Replace the faulty VVL actuator.
• Repair or replace damaged wiring.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Diagnostic software

Moderate
• Nissan Altima
• Infiniti G35
• Nissan Maxima
• Regular maintenance of the VVL system
• Ensure proper connections in the CAN bus
• Routine ECM checks
Engine Performance
• Do not ignore the Check Engine Light.
• Consult a professional mechanic for accurate diagnosis.
• Avoid driving with this code active for extended periods.
Check with your vehicle manufacturer for warranty coverage on the ECM and VVL components.
This code is relatively uncommon and often associated with specific models that use advanced VVL systems.
Moderate – It is recommended to address this issue soon to avoid potential engine performance problems.
Driving with a malfunctioning engine system can lead to safety issues and may not comply with vehicle emissions regulations.
• Engine at operating temperature
• Vehicle in idle or low-speed conditions
The VVL actuator is typically located on the engine cylinder head, near the intake or exhaust camshaft.
Q: Can I drive with a P1035 code?
A: It's not recommended to drive for long periods with this code, as it can affect engine performance.
Q: How can I reset the P1035 code?
A: You can reset the code with an OBD-II scanner, but it's important to fix the underlying issue first.
