Is there any way to reset the codes on my '91 Turbo? I don't want to pay Toyota $70. Thanks.

i think u can reset the codes by pulling the battery terminal off for a few mins.....but if ur getting any CEL lights...you will have to fix the problem for it go away......

as above you would like to know WHY its on even if its a temp sensor failing

save you some money in long run !!!!

You can just pull the EFI fuses in the engine bay to clear codes as well.

i heard a way you can actually go into the diag and jump 2 terminals with a wire, and it will flash a certain sequence on the check engine light inside. and depending on how many times it flashes that determines what is wrong with it. honestly i dont know much about the method but it can be done.

^^a simple paper clip will do....that is to read the codes....not clear them......

91MR2NASTL, the original poster was asking how to reset the codes, not read them

Thanks for all the help. The codes that I pulled were: knock sensor and O2 sensor. The problems should be solved now, that's why I asked about clearing.
