a friend of mine has a 91 si with a zc and pm6 in it ......the pm6 has the led in the ecu to chec codes.....but he also had a check conector for the check engine ligt but it doesnt show the codes when i jump the conecctor....

and i can tell if hess getting a code 20 or a 14 and a 6 (14 and 6 is what it seems to me )hes having idle problems and stalling ...i guess it could be the ELD or IAC......but how well would it run with the engine coolant sensor code on ???

thanks

 

There is no need to jump an OBD0 ECU. THe CEL will flash the codes on the ECU.

Code 14: one long 4 quick flashes
Code 6: 6 quick flashes.

 

ok cool thanks

so the led on the ecu should still blink long for 10 and short for 1

cuse there is no longs at all and there 20 blinks before it starts over ...not a long in site
ill go check it agian

 

No longs

 

k thanks

 

whats the delay inbetween codes...like i sia di cand tell if its a 20 or a 14 and 6......i thiught there was a bit of a pause but hardly any ....after 14(IAC) whitch would explain the stalling but th ELD could be it too cause its only at night when every thinfg is on thats it stalled

 

Theres like a 2 or 3 second pause between codes,you just have to pay real close attention and you'll see it.

It may not even be necessarily that long- it is long enough to see a break between codes- you just have to watch.

BTW I never get any long flashes for ten- it's always ten short flashes
