2001 Lexus ES300 ProblemsCheck Engine Light Due to Failed Oxygen Sensor
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.
The 1993-2003 Lexus ES300 may start and stall, or start and run at very low engine speeds when the engine is cold.
The issue is a failed or dirty idle air control valve. This valve is mounted under the throttle body, and modulates airflow to the engine under certain conditions. When the valve becomes dirty, or when the valve fails, proper airflow to the engine is not achieved. This results in start and stall, and low RPM.
To correct the issues, the idle air control valve will need to be tested, and cleaned or replaced.
To help decrease the frequency of this issue, change the air filter no less than once per year.
The Lexus ES300 has a known issue with the valves that if left unchecked, will cause burned valves and engine performance issues.
The engine ‘breathes’ through valves that are pushed open by the camshaft, and closed by springs. When valves are closed, they seal against a valve seat. In this vehicle, the valve seat is too soft, so after the valve contacts it thousands of times, it becomes crushed. Once it is crushed, the valve can no longer make a proper seal, and the valves erode due to extreme temperature (burnt valve).
Symptoms related to this issue:
- Rough idle
- Backfiring through exhaust or intake
- Illumination of the check engine light
- OBD Trouble Codes P0300, P0301, P0302, P0303, P0304
- Loss of power
- Engine Stalling
To repair the burnt valves, the cylinder head must be removed and rebuilt, which is a costly internal engine repair, however, this issue can be prevented through inspection and adjustment of valve clearances every 40,000 miles.
2001 Lexus ES300 QuestionsVehicle skid control system and trac off indicator lights always come on. (1 answer)
This only happens when the outside temp is over 80 degrees. When I turn off the car and restart it the lights go away. Sometimes they stay off but when I start driving again , they may or may not come on again.
when driving around 40 mph the rpm's will drop and the car will like bog down and sound like it is retarding or something like that then if I push the gas it will kick pack in and go ? it doesn't do it all the time I will drive it one time and be fine and then I will drive it and it will...
My car has a noise coming from the engine that a mechanic told me sounded like a worn out bearing somewhere. Not wheel. Makes noise in park.
