Regulate oil flow to the exhaust camshaft phasing system with the Walker Products Engine Variable Valve Timing (VVT) Solenoid 590-1157. This OE-replacement variable valve timing solenoid drops in for the 2012-2020 Mazda 3, 2013-2020 Mazda CX-5, 2016-2020 Mazda CX-9, 2014-2020 Mazda 6, and 2016-2020 Mazda CX-3. Cataloged for the exhaust position, it controls the flow of pressurized oil to the cam phaser or VVT sprocket, adjusting valve timing in response to engine load and speed to support fuel efficiency, throttle response, and emissions.
- Controls camshaft timing: actuates oil flow to the VVT sprocket to alter valve opening angles across engine loads and speeds.
- OE-replacement calibration: matches the original electrical specs, oil flow rate, and response timing for precise engine control.
- Built for harsh environments: oil-resistant seals and a heat-tolerant plastic housing with precision-machined internal valves.
- Exact OE fit: installs using the factory connectors and mounting points with no modification required.
Over time a solenoid can clog, stick open or closed, or fail electrically, which may set fault codes such as P0010–P0014 or P0020–P0024 and cause rough idle, hesitation, or reduced power. If a sticking or failed exhaust VVT solenoid is the cause, this unit replaces it. See the "Vehicles it fits" section for engine-specific applications.

Frequently Asked Questions
What does the Walker Products 590-1157 VVT solenoid do?
It regulates the flow of pressurized oil to the exhaust camshaft phaser or VVT sprocket, adjusting valve timing based on engine load and speed to support fuel efficiency, throttle response, and emissions.
What vehicles does the 590-1157 fit?
It fits the 2012-2020 Mazda 3, 2013-2020 Mazda CX-5, 2016-2020 Mazda CX-9, 2014-2020 Mazda 6, and 2016-2020 Mazda CX-3. Check the "Vehicles it fits" section for engine-specific applications.
What are the signs an exhaust VVT solenoid may need replacing?
A solenoid that clogs, sticks, or fails electrically may set codes like P0010–P0014 or P0020–P0024 and cause rough idle, hesitation, or reduced power. Diagnose the cause before replacing.
Is this a direct-fit replacement?
Yes. It's an OE-replacement solenoid that installs using the factory connectors and mounting points with no modification required.
Which position is this solenoid cataloged for?
It is cataloged for the exhaust camshaft position, controlling oil flow to the exhaust-side VVT sprocket or cam phaser.
