I have a 2000 Civic Si. It has been swapped with a JDM b16a engine using my b16a2 intake manifold, oil pump, etc (to convert to OBD2). After the swap, the check engine light is on. I found the error codes from Advance Auto Parts and they are:

P0117
engine coolant temp
circuit low input

P1508
Manf Cntrl Veh. Spd.
Idle Speed Control
Auxiliary Inputs

I have no clue how to fix these. I tried to clean the IAC valve, but nothing happened. Some problems are the high idle (about 1500), rough start when the engine is cold, and no sound of VTEC. PLEASE HELP!! I really want my VTEC working! Thanks!!

try the CELL thread : https://honda-tech.com/zerothread/1901557

 

So after I change my coolant temp sensor and clean/replace my IACV, my CEL will go away? I'm not real sure if this is the right way to fix my codes. tell me how to fix them, if there is more to it. and does these things suppose to affect my VTEC? because when i floor 2nd gear all the way to 8200, it lags around 6000. plus you can't even hear VTEC rip in. help me out if you can!! it's well appreciated!!

 

Unless ur oil pressure is owned u'll throw a CEL at the VTEC engagement point if it doesn't kick in.

you don't know if you dont try, just borrow a friends and see how it works

 

I can vouch for the "no VTEC with the ECT sensor being bad" thing. Going through it right now with my damn EM1. Good ole' error #6. It's a bitch.
