Connect the VTEC solenoid valve 1P connector terminal No. 1 and body ground with a jumper wire. VTEC SOLENOID VALVE 1P CONNECTOR Wire side of female terminal Check for continuity between ECM/PCM connector terminal B15 and body ground. ECM/PCM CONNECTOR B (24P) Wire side of female terminals Is there continuity? YES - Go to step 14. NO - Repair short in the wire between the VTEC solenoid valve and the ECM/PCM (B15).

Install the special tools as shown. Reconnect ECM/PCM connector B (24P) and the VTEC solenoid valve connector. Connect a tachometer. Start the engine. Hold the engine at 3.000 rpm (min-1) with no load (in Park or neutral) until the radiator fan comes on. Check oil pressure at engine speeds of 1,000 and 2,000 rpm (min-1). 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/cm2, 7 psi)? YES - Go to step 19. NO - Inspect the VTEC solenoid valve (see page 11-553).
