1. Remove flywheel. (See page 3-66.)
2. Remove the three bolts and fuel hose guard.
3. Remove bolts and MAP sensor from intake manifold.
4. Install MAP sensor into special tool.

5. Connect vacuum pump gauge (with hose) to MAP sensor
(special tool) as shown in figure.
6. Turn ignition switch ON.
7. While applying negative pressure (vacuum) to MAP sensor,
measure "12" terminal voltage. (See page 3-48 and 3-49 for
procedure.)
