Ok, so i just hooked up the P28 that i bought to my car. The only wierd thing, is that it's only throwing codes for the O2 sensor (expected), and the Vtec solenoid (expected.) Why isn't it throwing a code for the Vtec pressure switch????

 

bump!

There may be an issue with your wiring or the ECU. Hook up the spool solenoid and a 4 wire o2 sensor and see if you have any codes related to VTEC.

 

what year civic do you have?? all 92 civics were wired for vtec didnt matter what trim they were..

 

Just buy my P08,
ta-dah problem solved

 

What D15B do you have? the JDM one or the B7 or other? Also i dont think it would throw the pressure switch until you go into VTEC. Atleast thats my thought on it.

since he is talking about vtec i think he is speaking of the D15B (jdm).

 

He said that he was throwing a VTEC Soleniod code so maybe he doesnt have it, never hurts to ask.

 

it's the jdm d15b vtec

 

i know that on jdm b-series the solenoid is missing a plug that the us harness has. i talked to a guy who had a euro b16 and was running a usdm p30 ecu and it was throwing vtec code and wouldnt engage vtec. here is the link https://honda-tech.com/zerothread?id=869811 hope it helps you out.
