FUEL CUT-OFF SYSTEM

FUEL CUT-OFF SYSTEM:

For model with G200Z engine Preparation:
1) Start and warm up the engine thoroughly.
2) Turn the starter switch to the OFF position.
3) Disconnect the throttle valve switch harnesses at the connector, insert a fine wire into the idle terminal (upper), then make connections at the connector with the wire pulled part way out.

FUEL CUT-OFF SYSTEM:

vInspection
1) Keep the engine running at 2,500 - 3,000 rpm.
2) Check to make certain engine speed lowers to approximately 1,250 rpm when battery voltage is applied to the wire extending from the idle terminal.
Note: Engine shake may occur at the speed of 1,250 rpm or so, but it does not indicate abnormal conditions.

2) Turn the starter switch to the OFF position.
3) Disconnect throttle valve switch harnesses at connector, insert a fine wire into the idle terminal (upper), then make connections at the connector with the wire pulled part way out.
4) Disconnect the throttle position sensor at the connector. Use a piece of wire to connect the harness side connector terminals as shown in the illustration.
