Cpr no sync light

Post by accord96h22 » Fri Feb 15, 2019 10:20 pm

I have a 96 accord with f22b1 harness and obd2a to odb1 adapter(kstuned) into a P06 Ecu (kstuned s300v3 black Ecu).i have opened Ecu to verify q37 is installed. I am not getting a sync light after install. I have a h22 distributor with only the ckp sensor still wired. I have completely removed the icm and the coil from the distributor. I have the blk wire tapped to pin A23, red to A25, purple to pin A16, red/ylw to pin A22. have my 12v and tach attached to the proper wires. I downloaded my calibration checked all 3 boxes, hit upload and still no yellow sync light.

I have double checked the trouble shooting steps and it keeps telling me that i have a problem with my purple altc from Ecu A16 to CPR box.

I checked it many times and I do not see a problem with the wire, I do not have an oscilloscope to measure pulse but I do see voltage drop when cranking so it must be doing something. Thanks again

All 3 sensors in the distributor must be connected and working or it will not work.

I meant to type CYP, Must they all be in the distributor? I have my ckp and tdc on my oil pump (obd2 engine and harness). So all I would need is the cyp signal correct?

No, all signal must be seen by the ECU or it will not work. We have seen that some vehicles that have sensors in 2 locations have issues. You may need to use an OBD1 distributors that has all the sensors inside of it.
