engin light
 

can anybody help me my engine light was coming on so i had the 02 sensor changed then it still stayed on and the car was not running right so they changed the e.c.u chip for me and the car is running fantastic but the problem is the engine light and the light in the middle of the rpm (the red one ) stay on all the time . should i ignore it or is there anyway of getting them to go of as it bugges me
thanx

go in the engine bay
jus right behind the fusebox
theres a little black box with diagnostic written on it

get a paper clip or any conductive metal
and short the ts and e1 terminals

go back into the car, turn the key onto the on position
and count how many times the light blinks
it might get confusing at times, so dont blink

for a code 51 itll blink like this : . . . . . .
code 24 : . . . . . .
its kinda like morse code

good luck, let us know what you get

new problem
 

thanks for your reply ok the story sofar is they have changed the 02 sensor they have changed the ecu and the lights are still staying on they have done what you said with the paper click but its coming up with a code which is not reconised lol now they are doing the wiring loom they say it will be done today i hope so !!!!!

the only good thing for me is its under warrenty and i dont pay a penny the bad thing is they have had it for 2 weeks and they gave me a vw 1.4 golf and its a bag of s**t lol i will post reply soon to let you know if it gets fixed today
thanks

diagnostics... old toyotas don't require the plug in computer as the plug in computer don't actually recognise our diagnostic systems

do as above, go read your codes
put a wire in T & E1 or in some supras it's TE1 & E1
watch the check engine light

code 51 will be like this
flash flash flash flash flash....... flash

code 34
flash flash flash....... flash flash flash flash

pretty easy, now go do it


oh and you can't replace "chips" in toyota ecu's, it just doesn't happen... hope you didn't give them too much cash

report back with your codes

One more thing,
 

Good advice from the above posts, but as for the red light in the tachometer staying on, the only thing I can think of is it is the cruise control light. On the left side of the steering wheel is a button that says "Cruise Main". Hit that button and it should go off. Hope that helps.

Speed sensor problem
 

Mine returned with a speed sensor problem..
It also affects my idle (as it drops constantly and sometimes even stalls when i'm at a stand-still)

1994 supra non-turbo manual...
Any ideas?

I'm soon getting a 2jzgte half-cut so it will hopefully get rid of the problem..
So i'll be selling my engine, one thing is, i don't want to sell it with the problem.. I have already spent too much money trying to get it fixed and I don't want them to go through the same thing..

One mechanic said that the error code must be coming from the odometer reader.. Does that sound right to anyone or has anyone got any tips for me?

Thanks for any help I get, guys.
