Tightened gas cap and disconnected battery. Lights went out for about 5 miles and came back on. Did this twice. Took it to be scanned and got p0430 and p0420 codes. (It had been 6000 miles since my last oil change Got oil changed and had them check for loose hoses near air filter but they found none loose)
P0420 & P0430 You need new catalytic converter
The P0430 check engine light code, like P0420, means the catalyst system efficiency is below the required threshold. Simply put, this means your car is adding more pollution into the air than it's supposed to.
SOURCE: Check engine and svc light came on Toyota Highlander 2002
Check vacuum hose has come loose or gone bad from back of air filter box?
SOURCE: vsc & trac off indicators
Have you scanned both the engine computer and the abs computer? Because it is an abs problem, likely a wheel speed sensor.
SOURCE: Why is the vsc light check engine light and trac
to reset for a momentany malfuntion,disconnect the negative battery terminal few minutes, reconnect,start engine and drive to check
SOURCE: Check Engine Light, VSC and Traction Control Off Light, came on after oil and filter change
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
SOURCE: VSC TRAC, TRAC OFF, and CHECK ENGINE lights
it was trigger by the unconnectedc sensor at the air box. go to an autozone or sinilar parts store. most have a code reader they can put on the car for free and give u a list of codes.
