Well my bone stock 88 DX (DPFI D15B) is now throwing a code 15 which is ignition output signal.
What exactly is not working? How do I check and if necessary replace the part(s)?

 

code 15 is your coil/ ignitor. it lives in the distributor and it should be a big black plastic box. Did this problem just start or did you change something/ work on the car? a new coil is like $100 from kragen. i think you could find a whole distributor from a D15 for like $50 since so many people swap em for mpfi or new engines.

 

just started happening yesterday.
so it has to be replaced? no 2 ways about it?

 

check your connections there should be two screws connecting 2 wires to 2 terminals. make sure they are tight.

 

Sounds like your ignitor is headed south for the winter. Download a helms manual(search this forum for the link) and run through the troubleshooting flow-chart. If I remember right it can be 1 of three things, bad wire/connection, bad ignitor, or a bad ecu...

HTH

 

bump, as i'm still gathering ideas until i have time to work on the car

i got this problem also .. my tach and speedo trip the **** out .. im pretty sure im due for a new coil soon =T

 

Have you tried resetting the ecu? I have thrown this code with both the d15 and b16, resetting the ecu got rid of the code every time.

 

damn im gettin that code too, but as soon as i disconnect the battery and reconnect it the car runs fine.....wtf???????
