MAP SENSOR OUTPUT VOLTAGE CHANGE
" 09917-47011: Vacuum pump gauge
09930-89340: 26-pin & 34-pin test cord
09930-99320: Digital tester
$ Tester range: % DCV (See chart for range.)
1. Remove ring gear cover and silencer case. (See page 6-2.)
2. Remove bolts and MAP sensor from collector assembly.
3. Connect vacuum pump gauge (with hose) to MAP sensor as
shown in figure.
4. Turn ignition switch ON.
5. While applying negative pressure (vacuum) to MAP sensor,
measure “12” terminal voltage. (See page 3-49 and 3-50 for
procedure.)
