Start off by checking your gas cap to see if its on tight.

the vsc changes your driving, check your o2 sensors, mines came on with the vsc and the check engine, turns out it was the o2 sensor. but your check engine didn't come on so yeah idk try it though.

It should come on then go off. It will stay on if your car has a problem that reoccurs. You should have the code read at an autozone or other parts store.

Trying to figure out the same myself...

GO to an AutoZone and have the code pulled that's triggering the CE light. Search the code on here.

Mine's a P1349 if I remember right...I think its my oil control valve. Or its filter, but I may not have a filter on my 400, not sure yet... Digging into mine on Monday.

The plan:
1. Run 1/3 can of Seafoam through the crankcase, drive 50 miles or so and change the oil. Pull the oil control valve and clean it. Pull negative battery cable, eat lunch, and reconnect/drive to see if CE light returns. Should cost me $30. If not fixed...
2. Order an oil filter screen from Lexus (~$8) and replace. Complicated replacement on the 4.0 V8 involving bearing cap removal. If not fixed...
3. Order a new oil control valve ($~120?) for Carson and replace. If not fixed...
4. Dealership.

Pls, keep us update on what you did to fix it. Also, could you take a snap shots of the oil filter screen and oil control valve, if you can? Thanks and good luck with your fix.

Not that it matter, but where did you buy it from? Big dealer, mom & pop dealer, or private seller?

conroegs

it was a private seller..and i just talked to my homeboy he told me that on his 98 gs300 it dont come up, that it will only come up if the engine is messin up..

conroegs

well i had posted before that i was havin problems with my lexus gs300..well i got it scanned and it said i had p0430 but they cleared it said it prolly came up since i put lucas fuel injector cleaner..and then i got a p1121 code and it makes my car stay on limp mode and goes whenever it feels like it..i have to floor it in order to get it goin on..can someone tell me where i can get this app sensor or whatever its called for a good price i can do the install myself thanx
