I'm also throwing Code 22.

Checked the vtec pressure switch and it's good.

I then checked the voltage for the blue/black wire and grounded the other pointer of the multimeter and only getting 1.03volts. The Helms says it should be close to 12v. I immediately checked the voltage at the battery and getting 12+.

It says to "Inspect for an open or short to ground in the wire between the VTEC pressure switch and the ECM (ECU) C15. If the wire is ok, substitute a known-good ECM and recheck"

Any ideas? Could it possibly be a bad ECU (OBD1 P72 is what I am using)?

I can try my friends ECU (same Hybrid).

Thanks!

I'll check the oil level again, but I'm pretty sure it's good.
