Likely Causes
How to Fix It
1
Inspect the VTEC oil pressure switch connector for corrosion, moisture, or loose terminals
2
Test the VTEC oil pressure switch continuity; it should be open circuit when no oil pressure is applied and closed under pressure
3
Check the oil pressure switch wiring harness for open circuits or high resistance between the switch and ECM
4
Test the VTEC solenoid valve for proper operation; it should not remain energized at idle
5
Replace the VTEC oil pressure switch if it does not change state correctly with oil pressure changes
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
