I have a 91 civic that i converted to MPFI obd1 and everything is working great except the car keeps showing a code 19. I have the stock 91 transmission and lockup Solenoid in the car still. The Solenoid clicks when I put 12v to it and I have the single wire ran to pin D18 on the p28-A52 ecu. There is continuity from the pin to the plug on the Solenoid. Is this the correct pin and what else can I try to fix this. I noticed on the obd1 trans there are two solenoids and 2 wires I wonder if that has something to do with it.
