I have a 00 civic si and did a jdm b18c swap in it. the swap was done well and i am using a00 civic si wiring harness. i am also using a obd2a ecu that is suppose to be a type r ecu.

the only code im throwing is the vtec pressure code. I dont know what is wrong. I also swapped the vtec pressure switch from the usdm vtec solenoid and put it on the jdm one. still throwing that code. any suggestions??

that thread is nice but i havent checked my vtec oil filter but im sure its fine.. thrers no oil leaking from the solenoid

 

atleast you got a cel. funny i got the same car and the same swap only difference is im running a chipped obd1 ecu and my vtec just isnt working. even changed the oil and filter and checked the solenoid filter. im stumped

 

I am pretty sure if u just buy a stock obd1 ecu, u will be fine.. maybe thats what i need to do ?

 

Somebody correct me if I'm wrong but jdm b series don't have vtec oil pressure switches.

Is the ecu your using a us spec itr ecu?

 

 

okay so i ran my code today and it turns out it wasnt the vtec pressure code.. its throwing a knock sensor code.

I checked to see if the knock sensor plug *located behind the intake manifold above the oil filter plug and it is connected.. I cna click the plug in and evertyhign? should i swap oput the knock sensor from my hydrolocked b16?

 

bump.. will knock sensor code go away after replacing the sensor?

i dont here any knocks or pings in the motor, runs fine, hits vtec real smooth and idk its just a clean lookin swap.
