Detailed Product Overview

This vapor canister stores fuel vapors from the evaporative emission control system and routes them through the proper purge path when the system operates normally. Standard Ignition CP3090 is built for vehicles that use a two-port canister layout and is listed for multiple Nissan and INFINITI platforms, including Frontier, Pathfinder, Xterra, QX4, and Q45. The CP3090 part number is also a useful reference when matching the correct evaporative system component during diagnosis or replacement.

This part cross-references 2-29966 and CP1242 for the same application.

What It Helps Fix

Installation Notes and Tips

Verify hose diameter, port count, and canister length before installation. Match the vehicle’s emissions configuration, especially on 2000-2001 INFINITI Q45 applications with California emissions. Inspect connected hoses, clamps, and purge lines for damage or blockage so the replacement canister can operate correctly.
