Why does my VVT solenoid keep going bad?
The most common cause of failure for both the VVT switch and the VVT solenoid is a lack of basic maintenance. If your oil is dirty, sludge can clog the screen on the solenoid, causing a failure. If the engine oil level is low, you will also experience problems with VVT operation.
Can you drive without a VVT solenoid?
In some cases, the motor may run (not very well) with a broken or damaged variable valve timing solenoid, however it will likely not run for long due to the critical role the VVT solenoid plays in the timing of the motor.

Can a bad VVT solenoid cause stalling?

Where is the p1354 code on a Toyota Avalon?
My 2000 Avalon with 216K threw this code as well – left bank (closest to radiator). Car was cold so I disconnected the electrical connection (be real careful of the electrical tab as it is old and brittle and will most likely break–mine did). Used a 10mm 1/4 rachet and removed the bolt.
