19. Reconnect the VTEC solenoid valve 2P connector
and VTEC oil pressure switch 2P connector.
20. Connect a tachometer or OBD II scan tool/Honda
PGM Tester to the DLC.
21. Start the engine. Hold the engine at 3,000 rpm with
no load (in neutral) until the radiator fan comes on.
22. Check the oil pressure at engine speeds of 1,000
and 2,000 rpm. Keep the measuring time as short
as possible (less than 1 minute) because the engine
is running with no load.
Is the oil pressure below 49 kPa (0.5 kgf/cni,
7 psi)?
YES-Go to step 23.
NO-Inspectthe VTEC solenoid valve (see page 11-
128) .•
23. Turn the ignition switch OFF.
