Since the beginning of ownership, 4 months ago, my Lexus has been showing lights on the dash for:
VSC, have checked by dealer
Check engine
Traction control off
I would scan my car with your normal scan tool and it would read "camshaft position A actuator circuit". I ended up replacing both the sensor and solenoid on bank A. Neither of those things fixed the issue. $700 later, I replaced the timing control motor. More power, no lights and no issues. Passed inspection.
