Turn the ignition switch OFF. Disconnect the VTEC solenoid valve 2P connector. Check for resistance between the VTEC solenoid valve 2P connector terminal No. 2 and body ground. VTEC SOLENOID VALVE 2P CONNECTOR Terminal side of male terminals Is there 14-30 ohms? YES - Go to step 10. NO - Replace the VTEC solenoid valve. Disconnect ECM/PCM connector B (24P). Check for continuity between ECM/PCM connector terminal B1 and body ground. ECM/PCM CONNECTOR B (24P) Wire side of female terminals Is there continuity? YES - Repair short in the wire between the VTEC solenoid valve and the ECM/PCM (B1). NO - Go to step 12.

Connect the VTEC solenoid valve 2P connector terminal No. 2 and body ground with a jumper wire. VTEC SOLENOID VALVE 2P CONNECTORS Wire side of female terminals Check for continuity between ECM/PCM connector terminal B1 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 (B1).
