00 Rx300 - Check Engine And 'trac Off' Lights

[trout]

My CEL came on and so did the "TRAC OFF" indicator. when the trac off lights up, the switch will not shut it off, its like the switch becomes useless. I can restart it and the trac off lights goes away and the switch works fine, then a few miles later it comes back until i restart. The CEL and the trac off came on at the same time. the CEL remains on all the time.

I disconnected the battery and restarted, the CEL went away but came back on with the trac off light within 10 minutes. The car runs fine and I notice nothing different about it. Any ideas?

its a 2000 rx300 fwd with almost 90k miles. Seems to run great, tranny is a little clunky going from P to R or D when cold but other than that its a good running machine.

Thanks.

after some reasearch...

Im going to check the hose on the rear of the airfilter box, then disconenct the neg. battery cable for a while. if it returns, i will clean the MAF and see what happens.

others?

Why keep guessing? If you have a CEL indication then the computer has a fault code stored. I would take it to Autozone (or somewhere similar in your area) and have them pull the code for you (for free). Then go from there.

With a CEL indication the trac off is a default, automatic, indication, fix the CEL and the trac off will go off.

It's in the owners manual.

If you found out about the hose behind the air filter box I guess you finally got around to doing a search. Don't forget about the gas cap.

Gas cap seems correct. I did not see any lines/hoses off of the back of the airbox. I did take off the (i think) MAF sensor and swabbed it clean with a qtip, it had a small amber colored teardrop shaped sensor.

No luck on the CEL but i changed a taillight bulb and got rid of that indicator.

I also found a small puncture in the washer fluid resevoir that was allowing fluid to leak out causing the low fluid light to come on. I sealed it up and will add some fluid tonight. So if that works, then I got rid of 2 out of 3 warning lights. Im gonna try to make it to an autozone to pull a code.

the rx runs like a champ though, engine is smooth like butter, perfect idle, no surges, pulls strong. almost 90k miles.

Oh...on the MAF- did i clean it correctly or is there more to it?

All i did was remove the 2 screws and pulled it out and ceaned the amber colored end. I did not even disconnect the plug, just pulled it out enough. Do i need to remove it completely? is there more to it than the amber piece?

also...while looking around, i noticed thet that entire airbox assembly is not very secure. It easily moves around (the whole thing). Is this the norm?
