2003 Lexus ES300 Problems

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.

 

On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

I called orland park, and...

The check engine light stays on and computer stated that either the AF sensor or the oxy sensor in front of the catalytic convertor is defective. Do I have to buy both or is the a way of determining which of the 2 components has to be replaced.
