I'm guessing you have a swap, since the Si (the car in your info) didn't have VTEC. What motor/ECU are you running?

A few other notes:

Reference voltage to that sensor shouldn't be 12v, it should be more like 5v.

Is your oil level low, is your oil dirty/sludged, is the engine dirty/sludged? That could cause it.

If you've got continuity from that sensor to the correct pin on the ECU, and the other pin on the sensor harness has continuity to ground, it's probably the switch.
 
after i reset the ecu i get code 22 a few seconds after i start it, neither pin has continutity to ground with the car off
 
Dude, I just posted a huge picture that shows you what to do.


If the BLK terminal on the connector does not have continuity to ground with the ignition switch off, there's an open in that circuit. Ground the black wire going to the sensor.
