Hey guys, I'm a bit new to Lexus, and was wondering what the few dash lights could mean on the Lexus I'm thinking about buying. The car is a 92 LS400 with 182,000 miles. It has a yellow oil light on, a traction control off light on, and an Overdrive off light on. Is there some super expensive problem that these lights are indicating, or is there a common problem such as faulty senders that's just tripping the lights? Thanks a bunch in advance for the info.

If you're that new to these cars in general you might try checking the appropriate switches inside the car, at least for the TRAC light and the overdrive. The overdrive switch is on the shifter, and the TRAC switch is on the lower center console underneath the radio controls. I would assume that if you toggle these switches and the lights go away that those systems are working fine. I'm not really any authority on this to be fair.

Check the switches described. If not, and the engine light is also on then pull the codes. This is how; http://www.lexls.com/tutorials/intro/codereading.html
Also, probably low on oil.
