i just bought a d15b with p08 ecu it was throwing a 21 for vtec sensor so i changed the to portion with an american vtec sensor and now its throwing a 22 for vtec oil pressure i dont have the green sensor as it did not come on the d15b so i am wondering if the vtec sensor does both on the d15b and thats why the american sensor did not work please advise

thanks in advance

P08 ECU will look for a vtec pressure switch (VTPS) OBD1 D15B vtecs came with a pressure switch so i'm guessing you actually ended up with the OBD2 3 stage vtec version.

easy to tell does your vtec solenoid look like this



3 stage

or this



regular VTEC solenoid

single switch but did not come with the green switch came with a plug in where the green switch would be asked on a different forum and they said it didnt need it but if it does thats an easy fix
