    I have a RX300 2002 that I purchased in July of last year so far only minor problems the car had 80,000 mi at purchase but what's brothering me is I hear a slight hum when I am idleing at stop light I've had this checked by a certified mechanic who only works on Lexus he hears it too he put it on a machine, checked everything to no avail I had a small hole in my flex pipe he changed that other than that the car runs like a dream for a 9yr old car. It was a one owner car no accidents garage kept paint looks like new. Does anyone else have this problem? It's not loud just annoying . In winter it's a little louder in summer not so.

    other day we had the same problem 0n 2001 rx300 with codes 1130 & 1150 and also lean bank1 & bank 2. misfire cylinder #1,3&5. we changed the camshaft actuator solenoid on bank1. test drove the car- got no more misfire cylinder #1,3 &5. but still had codes 1130 , 1150 and bank 1 & bank 2 lean. we cleaned out the fuel injection system and done deal. problem fixed. clean fuel system on this car take a long time to disable the fuel pump.
    to save time we ran a hose from fuel outlet to direct to fuel tank cap.
  • '01 "AWD" RX300, ~90,000 miles.

    Diagnostics indicated both l/r rear speed sensors out plus rear vehicle heigth sensor out.

    Suspected, inspected, for rear cable broken, kicked up road debris...?

    Nothing there.

    Opened passenger side kick panel and discovered.....WATER.

    Connector set, IM1,IM2, SOAKED.

    Water source, dripping, seems to be quite high up, seemingly just to the right of the CD player "box". Disassembled inlet cowling but could not replicate problem even with water pouring down the windshield and into the air inlet ducts for A/C intake airflow.

    Disconnected, cleaned and dried ,(hair dryer,) both IM1,2 connectors and fault indicators extinguished.

    Anyone experience this...? Ideas for fix?

    Prices are a little steeper, $185 Coil - back odd cylinder labor around $230. $415 total plus tax on coil at Lexus of Las Vegas.

    I currently just had lights turn on again without vehicle shaking.

I replaced bank 2 sensor 1 cleared code and lights came back ten minutes later I checked the hoses on the air box not disconnected.. what do you mean by cross pins 14 and 24?? maybe this could help me with my problem?

    Thank you all for suggestions to check gas cap. All dash lights went off after tightening cap!! :)

    Recently, all the usual suspect lights lit on our '02 RX300. Turned out to gas cap was cracked, new gas cap and the lights went out. For about a week: came back on, need a new vapor recovery valve, which means need a whole new vapor recovery canister. Which means $$$. Putting it off, as I'm assured only performance/mpg is being affected (and spark plugs), not polluting. And I'll need four new tires before the snow flies...any suggestions for tires?

    '13 Jaguar XF, possibly my favorite of all the cars I've owned. But, my '09 Jag XK was a beauty, as was my '05 Acura TL, '88 Acura Integra, '84 Mitsubishi Mirage Turbo & '78 VW Scirocco (my first!). And, of course, the '92 Nissan Sentra SE-R and '95 Saab 900s I bought for the ex... Ok, I like a lot of the cars in my life.

  • Hi ! I have the same issue with those three lights the thing is when they come on the motor shakes a little and the next day it's smooth but with the three lights on still. Can anyone help me with that?
  • Lexus RX300 : Year 2000 . I got a new battery . The next day , I saw engine sign on dash board . I thought it is O2 sensor . However , the same night after a stop for 15 minutes ,the car will not start and clock is reset . The car started after using jumper cables . The car now starts fine and engine sign is gone . However , I wonder if the problem will return and whether the engine sign means that the battery is dying or something wrong with the alternator . I would like to fix the problem before it can happen again . Any ideas ??
  • When I searched for the CEL, Traction Control and VSC lights on issue . . . "somewhere" on one of these forum-type sites was buried a suggestion to remove the EFI fuse (#14) for 30 seconds. I did and voila, the lights went out and have not come back on (it's been a week)!
