Walker 590-4002 Engine Variable Valve Timing (VVT) Solenoid Filter

Walker VVT Solenoid Filter for Honda Civic

Walker 590-4002 is an OE replacement engine variable valve timing solenoid filter built to keep oil flow clean before it reaches the VVT actuator. It uses a stainless steel filter element with a black rubber gasket for a precise seal in the original bore or housing.

Compatible with 1996-2005 Honda Civic and 1996-1997 Honda Civic del Sol applications, this filter is a direct service part for timing-system maintenance on Honda engines. Walker 590-4002 helps maintain proper oil passage control in the VVT system.

Key Features

• Stainless steel filter media for oil filtration in the VVT solenoid circuit
• Black rubber gasket for sealing at the OE mounting point
• Chrome filter finish
• OE replacement fitment for Honda Civic and Honda Civic del Sol applications
• Built for engine oil exposure and high-temperature operation
• Walker 590-4002 part number for easy identification

Detailed Description

The VVT solenoid filter sits in the oil path ahead of the actuator and helps keep contaminants such as sludge, varnish, and fine metal particles from reaching the timing control system. On Honda Civic and Civic del Sol engines, a restricted or dirty filter can contribute to cam timing faults, rough drivability, and diagnostic trouble codes related to timing performance. Walker 590-4002 is engineered as an OE-style replacement with filtration efficiency and oil pressure compatibility aligned to factory requirements. Use Walker 590-4002 when servicing a timing code, replacing a solenoid, or performing preventive maintenance on the VVT system.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Camshaft timing fault codes such as P0011 or P0014
• Restricted oil flow to the VVT solenoid
• Sludge or varnish buildup in the solenoid filter screen
• Rough idle or drivability concerns tied to timing control
• Premature wear in timing-related engine components

Installation Notes and Tips

Install the filter into the original bore or housing and verify the sealing surface is clean before assembly. Inspect the VVT solenoid and surrounding oil passages for contamination before reassembly. For best results, confirm the vehicle application by year and model: Fits 1996-2005 Honda Civic, N/A; Fits 1996-1997 Honda Civic del Sol, N/A.

Quality Assurance

Walker Products manufactures this filter to OE replacement specifications for filtration efficiency, oil pressure compatibility, and fitment. The stainless steel filter and oil-resistant rubber gasket are selected for the engine environment and consistent service performance.
