Restore precise valve timing control on the 2012-2015 Scion iQ with the Walker Products Engine Variable Valve Timing (VVT) Solenoid 590-1172, an OE-replacement unit cataloged for the exhaust camshaft position. It regulates the flow of pressurized oil to the cam phaser or VVT sprocket, adjusting valve timing in response to real-time engine load and speed to support fuel efficiency, throttle response, and emissions control.
OE Replacement Calibration: Matches the original electrical specs, oil-flow rate, and response timing for precise engine control.
Exact OE Fit: Installs using factory connectors and mounting points with no modification required.
Built for Harsh Environments: Constructed with oil-resistant seals and a heat-tolerant housing to withstand long-term engine operation.
Controls Camshaft Timing: Actuates oil flow to the VVT sprocket, allowing optimized valve timing for power, fuel economy, and emissions.
Over time a VVT solenoid can clog, stick open or closed, or fail electrically — often setting codes such as P0010–P0014 or P0020–P0024 and producing rough idle, hesitation, or reduced power. If a failed solenoid is the cause, this Walker unit replaces it and is built to OE-level tolerances for electrical response, oil-flow control, and pressure regulation.

Frequently Asked Questions
Does this VVT solenoid fit my vehicle?
It's a direct-fit replacement for the 2012-2015 Scion iQ. Check the "Vehicles it fits" section to confirm the exact application for your engine.
What camshaft position is this solenoid for?
It is cataloged for the exhaust camshaft position.
What does a VVT solenoid do?
It regulates the flow of pressurized oil to the cam phaser or VVT sprocket, adjusting valve timing based on engine load and speed for fuel efficiency, throttle response, and emissions.
What are signs this solenoid may need replacing?
A clogged, stuck, or electrically failed solenoid can set codes such as P0010–P0014 or P0020–P0024 and cause rough idle, hesitation, or reduced power. Diagnose the cause before replacing.
Do I need special hardware to install it?
No. It installs using the factory connectors and mounting points with no modification required.
