Hi Can enyone help me. I have a 1999 windom 3.0 G. 1MZ-FE engine. The Engine check, TRC and VSC lights all come on at the same time. They go away when you turn the ignition off and back on again. The local dealer put the tester on it and said the no 2 knock sensor is faulty. I replaces this myself as I used to work for a toyota dealership. This did NOT fix the problem. The lights still come on and the car seems to loose a little power and the shift pattern changes. Thanks trotski
