Camry Coupe 2-Door V6-3.0L (1MZ-FE) (1996)
EGR Control Solenoid: Description and Operation
PURPOSE
The Vacuum Switching Valve for Exhaust Gas Recirculation (VSV for EGR) controls the regulated vacuum applied to the EGR valve. The
Engine Control Module (ECM) uses the VSV to prevent EGR operation when the engine is cold to improve driveability.
OPERATION
The VSV receives voltage whenever the ignition switch is turned on. When EGR is required, the ECM grounds the remaining terminal which
opens the VSV vacuum passage allowing vacuum to the EGR Valve.
