with this type of an issue, you should diagnose the car with a computer, as the check engine light has set errors in the memory that need to be read and rectified... while a speed sensor might be the original issue, without proper diagnostics you are shooting in the dark in the "under-the-bed-monsters" - you never know if there is a monster, and if there is one, if you hit it...
and a word on chinese speed sensors - it has been established on this forum, that certain items do not warrant buying chinese knock-offs, and the speed sensors fall into that category... too many folks bought the knock-offs, just to dump them and buy the OE...

Occasionally, if I haven't started the car for a while, when I go to start the car, I get a 'Trans Failsafe Prog' error. This is rectified by turning off the car and starting it again. It does not appear after that. This happens maybe once a month, if the car goes for longer than a couple says without starting. Could this maybe have something to do with it? The service engine soon light is always on. I have never seen any ABS or Traction control lights. I will avoid eBay. Any suggestions on where to buy a quality OEM speed sensor?
