How to Check and Clear a 1994 VTEC Solenoid

The 1994 VTEC engine was used in a number of Honda vehicles, including the Civic, the Prelude and the Del Sol. Known for its reliability and power, the 1994 VTEC is still prized among car enthusiasts. Although these engines generally wear well over time, one common failure point is the solenoid. If your 1994 Honda engine is having trouble starting, it's likely your solenoid could be stuck. Before you take your car into the shop for an expensive solenoid replacement, you can check and clear it yourself.

Instructions

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.
