Hey so the engines a 92-95 d15b 1 vtec solenoid cars a 96 civic cx hatch . Ive had this code since the swap trying to get rid of it. Looks like the guy who swapped it wired and grounded the pressure switch right i hv a p28 ecu with the jumper harness into the obd 2 car . Today i did the vtec bypass thing by connecting jumper wire from a2 to d3 and light went away but it comes back on.after driving ten minutes or so. Shut car off light stays off and comes on again after driving a while . It stays off even while car is warm. Is there a reset i need to do or wondering if possibly vtec solenoid is bad or clogged ?(i hv no meter to test anything and dont want to pull the solenoid off if i dont have to) Keeping in mind ive had this code since day 1 and the engine had 80000km on it . It was off an auto car though and mines msnual if that matters ..Or could it be my oil pump or just the fact that the obd2 no vtec car cant work with vtec? Any help is appreciated !
