This OE replacement solenoid regulates pressurized oil flow to the cam phaser or VVT sprocket, helping maintain smooth throttle response, fuel efficiency, and emissions performance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOE replacement Engine Variable Valve Timing (VVT) solenoid\u003c\/li\u003e\n\u003cli\u003eSilver housing with black connector color\u003c\/li\u003e\n\u003cli\u003e1 female connector, square shape\u003c\/li\u003e\n\u003cli\u003e2 male terminals, spade terminal type\u003c\/li\u003e\n\u003cli\u003e3 mounting holes for factory-style installation\u003c\/li\u003e\n\u003cli\u003ePrecision internal valve design for oil flow control and pressure regulation\u003c\/li\u003e\n\u003cli\u003eHeat-resistant plastic housing and oil-sealed connector construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow This VVT Solenoid Works\u003c\/h2\u003e\u003cp\u003eThe Walker 590-1197 is built to meet or exceed OE electrical response and oil control requirements for dynamic camshaft timing systems. When the engine control system commands a timing change, the solenoid meters oil to the cam phaser so valve timing can adjust to load, speed, and driving conditions. This helps restore factory-level operation on applications such as Chevrolet Camaro, Chevrolet Corvette, Cadillac CTS, and GMC Sierra 1500.\u003c\/p\u003e\u003cp\u003eThis part cross-references Standard Ignition VVT376 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Problems It Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine lights with timing-related fault codes such as P0010-P0014 or P0020-P0024\u003c\/li\u003e\n\u003cli\u003eRough idle caused by inconsistent cam timing control\u003c\/li\u003e\n\u003cli\u003eHesitation or reduced power during acceleration\u003c\/li\u003e\n\u003cli\u003eSticking open or closed due to oil contamination or wear\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy and increased emissions from incorrect valve timing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Fitment\u003c\/h2\u003e\u003cp\u003eCompatible With 2014-2020 Cadillac Escalade, Escalade ESV, and CTS; 2014-2019 Chevrolet Corvette; 2015-2020 Chevrolet Tahoe; 2016-2019 Chevrolet Camaro; 2014-2018 Chevrolet Silverado 1500; 2018 Chevrolet Express 2500 and Express 3500; 2014-2018 GMC Sierra 1500; 2015-2019 GMC Yukon and Yukon XL; 2018 GMC Savana 2500 and Savana 3500; and 2019 Chevrolet Silverado 1500 LD and GMC Sierra 1500 Limited.
