I have a 1999 ES 300 with the same problem. I took it to an independent repair center, (Big O Tires). They ran the codes and it told them it was one of three oxygen sensors in the car. There are two sensors for the engine, (one on either side of the V6 engine), and one for the catalytic converter. The bad part is this sensor is located AFTER the cat. converter, which means it could be the converter, (about $1500.00), or the sensor, (about $250.00). After checking all sensors, it was determined it was PROBABLY the sensor after the converter. I had the sensor replaced and so far the lights have not come back on. Seeing that your car is a 2003 model, I really don't think it could be the converter. If you have been dealing with a reputable repair center, go there. Otherwise go to the dealer and see what they say. If they recommend the converter, push for the sensor. That way you are only out $250.00! Good Luck!!!

The Check Engine light, Trac OFF and Vsc lights are on. I cleaned the MAF sensor on the air intake. but it didn't help. What should I do?

Since your "check engine" is ON, have some fault codes stored in the PCM (Powertrain Control Module / computer); to know exactly about what codes are the, will need scanned the PCM wit OBD II scaner reader tool; some autozone or autoshop with this tool make this for free. The check engine light can come on for 1 of about 200 different reasons, most times it's something simple such as a evap leak or loose gas cap.

As a factory default any time the check engine light comes on the TRAC and VSC systems are disabled as a default.

Soft reset could be disconnected the battery few minutes (sometimes work), but if the codes turn on again, is confirm, have fault codes stored and need to know what is to solve it.
