You would need to fix the problem, then have the computer re-scanned to erase the codes.

SOURCE: i have a 1996 lexus 400 LS. My check engine light

P0420 is "catalyst system below efficiency". It means that the car thinks a catalytic converter is bad. It could be that the cat is failing, but it also may be that the secondary oxygen sensor (behind the cat, used as a comparator to determine the health of the cat) is failing. As that part is about 10% of the cost of a new catalyst, I'd replace it first, have the code cleared, and see if it comes back.

SOURCE: the VSC and Check engine

Toyotas and Lexus cars have some unique feaures. If your fuel cap is loose or the O2 sensors on the exhaust are faulty this results in an emission problem and the engine computer unit (ECU) engages the check engine light and disables the VSC (the VSC light comes on to warn you that it has been disabled). However you have p0500 code which says the car has no speed sensor signal. The seed sensor is located on the side of the final drive from the transmission and its job is to measure the speed of rotation of the output shaft. The ECU will compare the signals from this shaft along with the speed sensors in the wheel hubs. If there is a difference between these signals the VSC is engaged to apply braking effort to which ever wheel is slipping (running faster) than the other or that the transmission speed sensor would warrant.
So you either have an emission fault has fed back to the VSC and speed sensor missing (p0500) condition, or you have a faulty sped sensor which has tripped the VSC light and in turn the CEL.
Check your fuel filler cap is on tight, turn radio off and disconnect the negative lead to the battery for 5 minutes (this should clear the ECU memory of the code error). If p0500 error and CEL and VSC lights come back on then check the electrical connection to the speed sensor. Ensure it is clean and making a good contact, check the wiring for continuity. If everything else looks good consider changing the speed sensor.

SOURCE: My son's 1999 Lexus ES 300 has a code of P0420 and

a common problem is the vacuum switching valves on the charcoal canister. These are small electrical solenoids with 2 vacuum hoses going to them. When you put power and ground to them they should click. Otherwise make sure there isn't a vacuum hose disconnected by the air cleaner box.

Your throttle position sensor might be stuck on the wide open throttle setting!

Do you have any check engine codes? Is the check engine light on?

It might not be if the TPS is still in the normal range...but is just sticking open.
