MAP Sensor Output Voltage Inspection
Z9J0111306013
1) Remove the flywheel.
Refer to “Flywheel Removal and Installation” in
Section 1K (Page 1K-5).
2) Connect the 36-pin test cord set between ECM and
wire harness as shown in figure.
Special tool
(A): 09930–88730 (36-pin test cord set)
3) Remove the screws and MAP sensor (1) 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.
Special tool
(B): 09917–49610 (Vacuum pump adapter)
(C): 09917–47011 (Vacuum pump gauge)
6) Turn ignition switch ON.
7) While applying negative pressure (vacuum) to MAP
sensor, measure “32” terminal voltage.
MAP sensor output voltage change
(at 759.8 mmHg, 101.3 kPa, 29.91 inHg
barometric pressure.)

8) If out of specification, Check wire harnesses for open
and short. If wire harnesses are in good condition,
replace MAP sensor and recheck.
9) Reinstall MAP sensor.
Refer to “MAP Sensor Removal and Installation”
(Page 1C-12).
