Ok, I am trying to figure out what is wrong with my computer. Its supposed to be a jdm b18c ecu.. and it might be, but I have always had trouble with code 22 (vtec oil pressure switch) We swapped vtec solenoids and press. switch from my car to a friends, and it still has the same problem. I have the blue wire going from the press switch to D6 on the ecu, and the black wire going to the ground near the thermostat. This engine code has been throwing since we did the conversion, sometimes it won't be on, then once the car gets warm, it will kick on. Hell... sometimes it will go for days without kicking on, others, just mere seconds. The only thing I could think of would be the computer is messed up or possibly its the wrong one.. I looked on ebay at gsr ecu numbers and found some differences btw them and the one I have in my car.

Mine is: 37820-P72-003
800-108734


while i found most others online to be 37820-P72-A01
970-1038-45


any ideas or know I even have the correct computer?

bump... someone's gotta know

 

It should be your v-tec silinoid

 

It is not the vtec solenoid... we have already replaced it with a known good one.

 

I tried man, sorry
