10. Measure voltage across the VTEC oil pressure
switch harness 2P connector.
Go to step 11.
Repair open in the wire between the VTEC oil
pressure switch and G101.
11. Turn the ignition switch OFF.
12. Disconnect the VTEC solenoid valve 1P connector.
13. Check for continuity on the VTEC solenoid valve
between the solenoid valve 1P connector terminal
and body ground.
Go to step 14.
Replace the VTEC solenoid valve.
14. Remove the VTEC oil pressure switch (A). Install
the special tools as shown, then reinstall the VTEC
oil pressure switch.
15. Reconnect the VTEC solenoid valve 1P connector
and VTEC oil pressure switch 2P connector.
16. Connect a tachometer.
17. Warm up the engine to normal operating
temperature (cooling fan comes on).
18. Check oil pressure at engine speeds of 1,000, 2,000
and 3,000 rpm. Keep measuring time as short as
possible because the engine is running with no
load (less than 1 minute).
Go to step 19.
19. Turn the ignition switch OFF.
20. Disconnect the VTEC solenoid valve 1P connector.
21. Attach the battery positive terminal to the VTEC
solenoid valve terminal.
22. Start the engine and check oil pressure at an engine
speed of 3,000 rpm.
Go to step 23.
Inspect the VTEC solenoid valve (see page
