will just like a paper clip work? I tryed that and the engine light is just on always and never blinks. Also there is a lot of white gunk in the diag. box, would that have anything to do with it?

Default Great!

Thanks, supra girl. I have no idea what "t" and "e1" mean, but I will try to search for this tomorrow.

My hood shocks are "tired", so I hate to look under my hood coz I need one arm to keep it up, or a stick, which I never keep around =P

hehe good luck with ya codes

look in engine bay
locate fusebox
beside fusebox = another box with diagnostic written on it
inside diag box on lid you will see pin diagram
find T & E1 (also known as TE1 & E1) on the lid then match up with diag pins and put wire or paper clip into those to connect them together and walah... your cel will flash or do something

sounds like code 52 which is knock sensor, check to make sure your plugs aren't broken and that (if turbo) both are plugged in (if na) that "the" knock sensor is plugged in

get a piece of wire and you should have to open the lid on the diagnostic box, inside the lid is a diagram of what each pin is, there you should find where te1 and e1 is

if ever you do a diagnostic and you have put the wire in but your check engine light stays lit and doesn't blink thats because the wire has not made firm connection in both of the terminals

That white gunk is waterproofing/dielectric grease that helps keep water out of electrical connections, and it also helps to promote electrical conductivity.

I would like to know what years this works for as well, I know it works for all MKIII, I don't know about the MKII or MKIV.

Anyone?

Typically will be the same for all toyotas 86-95ish

Some MK2's apparently have some sort of diagnosis system but I'm not sure which ones exactly, it's apparently a 2pin plug with a cap on it that you short.
