  1. My 2000 es300 get P0440, P0441, and P0446 every 300-500 miles. The fact that it takes that many miles to trigger the codes. Visual inspection of the charcoal canister and related valves look good. Any thought on this? Thanks.
  2. Thanks! Update: i haven't pull the abs motor relay yet. However, if i operate the car regularly, the noise goes away. If I keep in parked for a few days then the noise comes back. Very weird... For now i'll keep driving it and see. There're some other higher priority problems with the car to tend first.
  3. It's a 2000 es300. The noise comes from the air box side more towards the lower front of the car.
  4. Yes, that's correct. The buzz is there when the key is in off position. I've tested this some more and here's what I found: when the engine is cold ... like in the morning, the buzz is loud and prolong for minutes; when engine is hot, the sound is equally loud but just lasted a few seconds. The buzz/hum noise ends which a "tac tac" sound ... like a relay. By the way, where is the ABS relay? I've replaced the front rotors on the car recently ... could it be related?
  5. update: i put the starter back in. The noise takes longer to go away ~15 sec. It buzzes loud for 10-15 sec then become very low humm for another 5-10 sec then goes away completely after a relay clicks. When the noise is going, the voltage drop about 0.10V. Still suspecting some sort of short. The car drives ok as usual.
  6. i removed the starter ... same noise still but shorter 5-6 seconds. Now the noise seems to come from the trans case or below it. I unplugged the speed sensor connection and the noise still there. Battery is old but good. The voltage shows up ok both when engine on and off. A mechanic friend told me it might be the abs, is it??? How does the abs sound like? I mentioned earlier that this happens when i stick the key in the ignition -- no turning yet. What happens when the key is inserted? What stuff are powered on at this time? I've tried to listen for this noise on my other toyota-made cars but didn't hear anything. Any lexus gurus here?
  7. My es300 recently has a strange problem. When i stick the key in the ignition, there's a buzz noise coming out of the engine compartment ... more on the starter side. The noise continues until i take the key out. The position of the key doesn't seem to matter -- it's the same noise regardless of the position. The car starts and runs fine. Any thought? Thanks.
  8. On the general facts topic (http://us.lexusownersclub.com/forums/index.php?showtopic=1618) SKPerformance mentions "Their is recalls out for the charcoal canister having problems so if you replaced yours go to lexus and see what they can do." Does this apply to 2000 ES300 model? Mine has 160K miles on it, does it still qualify for the recall. I recently got P0441, P0446 and i wonder if these are related to the recall (if any). Thanks for any inputs.
  9. I had 3 coils blown in the last year too (ES 2000 158K). It was on the same cylinder #4 (CEL P0304). Did you find out the real cause for your case? I recently got P0441 and P0446 too. Really appreciate any info on this. Thanks!
