\015 2000 Toyota Pre-runner with 6 cyl engine, engine service light is always on and numerous mechanics (including Toyota Dealer Service) can find nothing wrong and no reason the light remains on. Will not pass CA smog because light is on.\015\012\015\012"the vehicle failed the MIL/check engine light due to failure to successfully complete all OBD self tests." This info is from the attempts to smog check.\015\012\015\012Numerous mechanics, including Toyota Dealer Service, have not been able to diagnos.\015
Not positive on this so consider only. The o2 sensor is what actually tells everything else what is going on with emmission and everything else adjusts to what info it relays. The o2 is also subjected to extreme temps and cooling cycles. So, instead of spending money on no answer diagnostism give replacement of o3 sensor so consideratio. If you choose to replace, wd40 and let exhaust cool down. Good Luck.
