OK, just swapped in my jdm d15b vtec with obd-1 conversion and p28 ecu. Car is running great, but I keep getting a code 15 after driving for awhile. Ive tried 2 different ignitors with the same result. Wouldnt a code 15 indicate a faulty ignitor and make the car run like ****? Maybe the car is running weaker than I should and I dont realize it because I dont have anything to compare it to?

 

Code 15 - Ignition Output Signal - missing or defective ignition output signal
I'd be betting you have a wiring problem somewhere. Does your tach work correctly?

**edit**
make sure you have good 12volt power on the blk/yel wire at the distributor.
also make sure that the yel/grn wire at the distributor connects to the red/grn at A21/A22 of the ECU.
plus your engine/trans grounds.

It seems to be working correctly, but I havent really taken it all the way throught the range yet. The light usually doesnt come on immediately, most of the time I have to drive a little while before it appears.

 

The jumper harness Im using is the one from blown90hatch. Could the ignitor be faulty even though the car runs fine? I made sure all the connections on the actual ignitor from the distributor are tight.

 

dude....you only need to post this in 1 forum only. come on now. allot of us read almost all the forums. no need to double post.

 

Thanks for your useful input
Besides, alot of people only read one of these forums, like I did before I changed my car to obd1. There is more useful obd1 knowledge among these guys than us EF guys. Hence that is why I have more replies in this thread than in the one in the EF forum.

Back on topic: I have good voltage to the black/yellow wire at the 2 pin connector on the distributor. Engine, trans, and t-stat housing grounds are fine.
