i am getting code 21/23 which is an unplugged or defective vtec oil pressure sensor and a knock sensor on my pw0 obd0 ecu for my ls/vtec crx.


i dont think ls motors came with a knock sensor.

now onto my problem...which is the vtec oil pressure sensor....it is wired up properly....now what are the chances of this sensor actually going bad? has anyone ever had to replace this sensor?
