like tha title says eh9 going into limp mode i cant figure it out y it keeps going in to limp mode i've checked tha code codes on it tha codes r
code 1 ----oxygen sensor
code 17 ---vss speed sensor
code 43 ---fuel supply system

i've replace all of these things and ireset tha ecu and it keeps going into limp mode need help plzz !!!!!!!

 

code 17 is probably why you are going into limp mode. did you follow the trouble tree or just pull out the parts shotgun and go to town?

you may haveto look at the helms and follow the trouble trees.

1 and 43 may be related.

 

is there any links to find tha trees i've just changeing parts and my speedo isnt working at all any more nor my temp gauge too
