雪佛兰科帕奇3.2及凯迪拉克车型碳罐真空电磁阀0280142495

For Chevrolet Captiva 3.2 and some Cadillac models, idle instability, starting difficulties, unusual fuel smell, or P0443 fault codes may indicate carbon canister vacuum solenoid valve (OEM 0280142495) failure. This valve sits between intake manifold and canister, controls vacuum for fuel vapor recovery, routing fuel vapors into the engine for combustion to reduce emissions and improve economy. Ensure hose seals are intact; replacement labor 0.5-1 hour; post-replacement canister evaporation system returns to normal.
