The check engine light was off for the last week. However, yesterday it came back on. I had it checked and it came back as a throttle position sensor error. I know that the sensor tells the computer where the throttle is, but what is it used for? Is it used for the variable timing? Would it be easy to replace? Or expensive?

I replaced the metal clips today and lubed the floats it defiantly helped. It just seems like a strange that the pads are always supposed to be in slight contact with the rotors. This is different then my 95 jeep grand Cherokee. Thank you for your help, I will be doing the rears tomorrow. Now I have another problem. The check engine light comes on sometimes. Not all the time. Does this sound like a particular problem?

Yesterday I replaced the front pads and rotors on my 1999 RX300. It seems like the pads on the caliper piston sides are rubbing the most. It is not too bad but it is defiantly noticeable. It seems like there is no way for the pads to retract from the rotors because the pads are held in by the metal clips and can not move freely. Any help is greatly appreciated. Thank you
