bbsal Posted July 3, 2003 Share Posted July 3, 2003 try the vapor pressure sensor.thats most likely what it is thats why your check engine light is on.theres also a vacum switching valve that works with that sensor and that might be the trouble.try the sensor first.

bbsal Posted July 3, 2003 Share Posted July 3, 2003 you can follow the vacum hose strait to the sensor by looking at the charcoal canistor and then follow the line in the back near the switch and you will see it go up to the sensor.the charcoal canister is usally on the left side near the brake fluid.thats how it is on mine anyway.

steviej Posted July 3, 2003 Share Posted July 3, 2003 when you fill up at the pump, do you force fill after the pump shuts off? If so stop doing that. I have read several post where people stopped doing that and the code associated with the Vapor and charcol canisters went away. If not, then call your lexus dealer. They should be able to tell you what the code means and what the fix is over the phone. steviej Quote Link to comment Share on other sites More sharing options...
bbsal Posted July 3, 2003 Share Posted July 3, 2003 i heard something about that also.when you over pump it gives the sensor a high pressure reading and thinks somethings wrong so the check light comes on. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 3, 2003 Share Posted July 3, 2003 also have heard it but never payed it any mind i fill and fill so i can measure my gas better to when the light comes on meaning i have 100km left form the light going on Quote Link to comment Share on other sites More sharing options...
bbsal Posted July 3, 2003 Share Posted July 3, 2003 me too!i always pump it till its about to spill over.one thing i dont do is let it get under a quarter tank because after you get under that you start to pull up the dirt at the bottom of the tank and that can cause fuel problems like fuel pump etc.. at least thats what i think but in order to get a good mpg reading you would need to run it down to near empty.
