Code P1035 Description
The Multi-Air valve train has a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The VVA Solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event, the VVA Solenoid is commanded to either hold oil pressure or bleed oil. The Variable Valve Actuator (VVA) Solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA Solenoid determines the intake valve timing and lift. This change on valve action is similar to creating a change in the camshaft lobe profile affecting the lift and duration of the valve opening. The Diagnostic Trouble Code (DTC) will be set when the PCM detects an open condition for the VVA Solenoid control.
What are the Possible Causes of the DTC P1035?
- Faulty Variable Valve Actuator (VVA) Solenoid
- Variable Valve Actuator Solenoid harness is open or shorted
- Variable Valve Actuator Solenoid circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P1035?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P1035 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

I just had my serpentine belt replaced on my 2012 vw tiguan then a few days later the Engine light came on than I plugged my Foxwell Scanner to the vehicle and the code read p1035 Nitrogen oxides (NOX) sensor-range/performance. is it possible that maybe something may have gotten knocked loose or do I need to replace that sensor?
-
Could you please double check the code number, I can find any information in the 2012 vw Tiguan factory service manual for the P1035 code.

I have a 2000 Silverado 1500 5.3l check engine light was on ob2 code reader said o2 sensor port 1 position 1 was bad replaced both position 1 an 2 sensor now it is giving me a 1035 code what do I do
-
Please double check the code number, there is no information in the 2000 Silverado 1500 5.3l factory service manual for the P1035

2019 compass with p1035, so jeep has variable valve timing huh, in their multi air thing. Too bad it doesn't work very well like vtec. Anyhow I have the worst trouble finding info on this jeep, like impossible to find a good wiring diagram or any breakdown like a good old Chilton manual. Do you know any of that info?

does this information apply to a 2004 4runner with the 4.7 V8 engine?
-
That specific code (P1035 – Cylinder 1 Oil Supply Solenoid Valve Driver Open Circuit) doesn’t apply to the 4.7L V8 in the 2004 4Runner. That engine uses a different variable valve timing setup than the later or smaller Toyota engines where this code usually appears.
If you’re seeing P1035 on a 4.7L, double-check the code with a scan tool—Toyota sometimes uses similar numbering for different systems depending on the year and market. On your engine, any VVT-related issue would typically show up as a P1349 or similar code for the VVT system, not P1035.
So no, this one isn’t relevant for your 4Runner. I’d confirm the exact code and engine details before chasing that circuit.
