THANK YOU GUYS !!! THAT WAS IT !!!!
PHEW !! Goodness Gracious.....I am lucky I didn't take it to my local Lexus dealership. They are a big ripoff. Last time I was there for oil change, I mentioned this problem to them, they said next time I come for oil change they would look at the problem but the guy already warned me that it does cost a bit to replace those sensors. I am glad I found this forum before :) Everytime I go there for a simple oil change, it coast me almost $ 150, Last time the guy said I needed some rotating tires *BLEEP* and all other crap....I bought his BS and it cost me almost $ 300. Hopefully I would learn something on this discussion group to do things on my own. Found the one tutorial by this Russian guy to change the oil. I might just try it myself.
