Question about 2002 Lexus ES 300

1 Answer

After replacing battery engine won't idle.

I replaced the battery on my '02 Lexus ES300 and now the engine will start but won't remain on unless I keep the gas pedal down about half way. If I let go of the gas pedal the engine will stop.

Hopefully,you can let it relearn itself.You will most likely have to try and drive it,the longer it runs,it will relearn,but if it does not,the dealer,will have to reprogram the computer.

Adjust the rpm, near the throttle body. Or clean the throttle body. If neither of those work, look into the idle air control valve.

Are you saying the engine cranks but won't start, or the engine won't crank ?
If the engine does not crank, you would check for voltage at the starter, the neutral safety switch, and the key switch as well as the ground connections.

My 94 lexus es 300 the engine light stays on n sometimes my battery light comes on wat does tat mean


Hi, the engine light is indicating that the computer has detected a fault. You will have to extract the trouble code to determine the fault. Go here for instructions on diagnostics: http://www.clublexus.com/forums/es300-and-es330/324049-obd1-check-engine-light-codes.html
Please get back to me with the results/trouble code for assistance in resolving the fault.

The battery light may be indicating a weak alternator. Check the voltage at the battery with the engine idling. If the voltage is less than 14 volts, replace the alternator.

Sounds like a problem I had with my 2000 ES300. Cleaning out the IACV (idle air control valves?) took care of it, at least so far.
