How to Check and Clear a 1994 VTEC Solenoid
- 1). Turn your Honda's engine off and engage the parking brake.
- 2). Open the engine hood.
- 3). Locate the red, positive charge wire running from your car's battery. The end of the wire opposite the battery is connected to the solenoid. Disconnect the wire from the battery.
- 4). Attach a multimeter lead to both of the solenoid's external contacts.
- 5). Turn the key in your Honda's ignition while watching the multimeter. If the multimeter registers a complete connection, the solenoid is working properly. If the multimeter registers an open connection, the solenoid is jammed.
- 6). Tap the side of the solenoid with a small hammer if the multimeter registered an open connection. Tapping lightly can help loosen contacts or plungers, which might be sticking.
- 7). Turn the key again and watch the multimeter. If the connection is still registering as open, you need to bring your Honda to a qualified repair technician to replace the solenoid.
