The Check Engine Light may come on because a component of the oxygen sensor stops working. Replacement of the failed sensor should correct this concern.

Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.
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.
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.
Intermittent failure of the purge control valve in the evaporative emissions (EVAP) system may cause the Check Engine Light light to illuminate.

2002 Lexus RX300 Reviews
My RX300 2002 Lexus has a wonderful ride and looks great even after 11 years. Well, that is where it all stops. I have spent more on this vehicle than any other car in my 53 years of driving. The transmission has been replaced, the motor on the antennae died, the front headlights go out frequently and sometimes the cruise control just stops when going up a hill. I'm taking it in next week to prepare for putting out more money.
I/we purchased this RX300 (also had a 1999) back in 2002 and this has been the reliable vehicle I've ever owned. No major or minor problems with this vehicle. I'm just now starting to have some under the dash noise like something is loose on the drivers side...anyone know what this might be?
The computer console screen that controls the radio and displays the heating and air temperature settings. The AC works but you have no idea what the setting actually is. The radio does not work at all.
I checked all the fuses and they are fine. The cost to replace this component is $ 1,500.00. It acts like a loose wire or a fuse attached to the screen.
Has anyone had any similar experience that had a simple fix?
I love this car. Just bought it from my mom who also loved it.
