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.

1996 Lexus ES300 Problems
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.
Sludge can build up in the engine because Lexus did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.
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.
The Check Engine Light may illuminate because the mass air flow sensor sends incorrect information to the engine control computer. This can cause a loss of power on acceleration. A failed mass air flow sensor will require replacement.

1996 Lexus ES300 Reviews
Purchsed in 2005 with 130K. Now have 301K...I maintain very well and Lexus is extremely reliable and relatively predictable. Transmission has had problems in drive,(starting at 275K) only when cold, but fine when hot. Engine is excellent.. Normal wear item repairs..Cooling fan runs off p/s and due to age the lines leading to fan are extremely important and needed replacement due to age.Most parts for this vehicle have cross over parts used in camry ( 1MZFE 6 Cyl) and Avalon various years that can be purchased for much less than through Lexus..(Ex. Brake Rotors and most engine parts)Highly recommend used if previous owner did basic maintanence.
Reliable Car. Enough said.
