I have a problem with a 2001 Lexus RX 300. It seems to be with the VSC sensor itself and not the light. We think ever since my wife was driving through a snow storm and pushed the ECT Traction button, the VSC system has never functioned properly again. When driving the car now, it seems like the system is constantly fighting itself for proper balance or control of the wheels. It feels like the car is stuttering and pulling, Sometiems when accelerating from a standing position, sometimes from turning, sometimes even going straight you can feel a pull through the wheel. We had tried disconnecting the ABS for a while which gets rid of the problem completely. But then we are not driving with it and living in the northeast, it helps to have that capability in the winter time. Can a VSC sensor be reset or replaced completely? How expensive is it to do that? And does a dealer have to do it.

no such thing as a catalytic computer... there is a catalytic converter ... part of the exhaust system so they may now be "guessing" that it's an O2 sensor. take the car to autozone... they will scan the codes for free.... post the codes here tho the lads and lasses there are pretty clever and will probably tell you what the codes mean.

go to auto zone, advanced autoparts, or a certified mechanic and ask if they can reset the codes, it should be free

SOURCE: Check Engine light and traction control light stay

there is nothing to do here but have the dealer run a scanner test to see what trouble codes were set with the lights coming on, until then there is no way to tell what the problem might be as there are over 200 possibilities.

SOURCE: trac off and check engine light for lexus es 300

A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.

The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.

The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.
