So you guys can stop posting error code threads now

 

Now you have to get them to read the stickies.

 

for our cars:

code 13 is coolant temperature
code 33 is o2 sensor

 

Bare with me, I'm new to diagnostics. How do u get these codes???

 

it tells you in the haynes manual, if you have one.

but basically when you are looking at your ecu, there is a slotted **** that you turn and it starts the diagnostic test that you select. then read the number of flashes per LED on it and you get your code.

 

turn the screw clockwise and wait for the leds to flash 3 times then turn it back counter clockwise. this is the diagnostics mode. from here the leds will flash individually indicating the code. the red led indicates the 10's and the green led indicates the 1's. i.e. if the red led flashes 2 times and the green led flashes 3 that would be code 23.

 

page 153 i think has all of the codes and such. somewhere in the 150's at least.

so if i set it to diag mode and turn the car on and it dosent flash at all i can assume that everything is good ?

 

Sounds like you do it a little different than I do. Turn the key to the "ON" position. Then turn the little screw on the ECU clockwise, wait for 2 seconds, then turn it back counter clockwise . Then the red light will flash in 2 sequences. Slow flashes indicate the first digit of the number, Fast flashes will indicate the 2nd digit of the number. Say it goes "flash....flash....flash...........flash.flash.fla sh....." That would be a code 33 which is o2 senor. If there are no codes in the ECU it would read 55. Turn the screw counter clockwise, hold it then turn it back to the original position.

 

My -91 is just like this, think they're different on older/newer models...

 

well it worked the same way on both my 89 and 94

 

ok, so i turned the screw clockwise and the light goes out, if i turn it back the light comes back on and does nothing, if i leave it turned the light flashes 2-slow, 3 fast, 4 fast, 5 fast, 1 slow. help me out
