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).
Is pressure below 49 kPa ( 0.5 kgf / cm , 7 psi)?
YES Go to step 19.
NO Inspect the VTEC solenoid valve (see page
6-10).
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.
Is pressure above 390 kPa ( 4.0 kgf / cm , 57 psi)?
YES Go to step 23.
NO Inspect the VTEC solenoid valve (see page
6-10).
