i have a crx with a b16 from a 99si running a 0bd2 p73 ecu, using a obd0 to obd2 jumper harness. Car runs perfect and throws NO codes, question is why are these sensors unplugged and its not throwing codes. Also can you give me the names of each one.

 

1- oil pressure
2- reverse light switch
3-evap purge

 

yea, number ones kinda important. do you even hit vtec?

 

yup vtec is perfect.. it my understanding now that the jdm type r ecus dont even read that sensor .... thats why its not hooked up
