Question about 2005 Toyota Highlander
When the lights came on I removed and replaced gas cap. I then disconnected the battery and this cleared the lights. Drove car and after 5 miles light came on agin. Did this twice. Got car scanned and got codes p0430 and p 0420. Had been 6000 miles since last oil change. Had oil changed and asked them to check for loose hoses near air filter. They saw no problem. Can you help? Do I have to gat my catalytic converter replaced?

The converters generally fail only after the truck has been running rich. I would not replace them until certain the engine is running properly. There is no harm to the car to drive with these converters. Was there any history of rich operation codes?

obviously they did disconnect a sensor while they were working on your vehicle.this will set a code in your vehicle's computer.They call this a soft code since there was not a failure but it just did not sense a signal.After reconnecting it clears the code after so many ignition cycles,meaning turning the key on and off so many times.The code is stored in the computer so it would be a good idea to take it to the dealer to check it out and make sure there are no other problems

You have to know what code is stored to fix the problem. Toyota's will generally display a Check Engine light, VSC and TRAC light all at the same time, even if it's a simple problem with an oxygen sensor (for example). You can disconnect the negative battery cable for a few minutes, even though you should a scan tool should be used, to clear out the code.
