Tech Tip: Don’t ‘Blow By’ PCV Inspections
Most emission control parts, like the PCV valve, require little if any scheduled maintenance, but replacement may be necessary if the Check Engine light is on, the vehicle has failed an emissions test or is experiencing a driveability problem. Other emission control components include the exhaust gas recirculation (EGR) valve, the evaporative emission control system (EVAP) vapor canister and purge valves, the catalytic converter, oxygen sensors and all of the engine’s other engine management sensors.
