Little background info. I have a 97 civic with a recently swapped z6 with my obd2 harness. Im running a chipped po6 with a z6/450cc base map.

Problem, I have a check engine light for vtec spool solenoid valve and vtec pressure valve.

I have the wire from the solenoid coming directly to the vtec wire on the obd2 to obd1 conversion harness. I also have the power wire for the pressure sensor wired in the same way.

Idk where I should connect the ground for the pressure sensor. I tried just doing it on the battery but nothing happens.

I soldered all of my wires together but still have the two engine lights. Need help.

 

dont know what to say because on a recent lsvtec swap i did i ran rad the grounf str8 to the battery.. are you sure your wiring your vtec and pressure switch right into the harness?

 

also i dont usually run it to the conversion harness i run it to the ecu plugs to make it look clean.. and you can really read what pinouts the wires are to go..

 

i got it figured out. i had my oil pres. wire soldered to a wrong wire. thanks.
