Check Engine Light With Codes P0440, P0441, P0442, or P0446 on Lexus RX330

The Check Engine Light may illuminate with various EVAP system fault codes stored. Our technicians tell us this may be caused by a sticking EVAP Purge Vacuum Switching valve. An improved valve is now available to remedy this problem.
