Engine Electrical Devices: 1C-12
7) Turn Ignition switch ON.
8) Measure the voltage when the tip of a steel
screwdriver is brought near and then pulled away
from the sensor tip.
When screwdriver is brought near
Approx. 5.0 V
When screwdriver is pulled away
Approx. 0.3 V
9) If the voltage does not change in the above test,
check wire harnesses for open and short.
If wire harnesses are in good condition, replace CMP
sensor and recheck.
10) Reinstall CMP sensor.
MAP Sensor Output Voltage Inspection
ZAJ6111306013
1) Remove STBD lower side cover.
Refer to “Lower Side Cover Removal and
Installation” in Section 2A (Page 2A-3).
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) Install STBD lower side cover.
Refer to “Lower Side Cover Removal and
Installation” in Section 2A (Page 2A-3).
NOTE
Keep the ECM connector and test cord dry to
protect them from water spray during the
inspection.
4) Start the engine, then shift into forward.
Gradually increase engine speed to 3 000 rpm, then
measure the voltage change at “32” terminal (sensor
output).
Special tool
: 09930–99320 (Digital tester)
Tester knob indication
DC Voltage
MAP sensor output voltage change
Fully closed throttle: Approx. 1.4 V (258 mmHg)
1 000 rpm: Approx. 1.5 V (290 mmHg)
2 000 rpm: Approx. 2 V (407 mmHg)
3 000 rpm: Approx. 3 V (604 mmHg)
5) If sensor voltage change is out of the specified value
or no linear variation, check wire harnesses for open
or short. If wire harnesses are in good condition,
replace throttle body assembly and recheck them.
6) Remove the 36-pin test cord, then connect the
connector to ECM.
IAC Valve Removal and Installation

Removal
1) Remove the ring gear cover.
Refer to “Ring Gear Cover Removal and Installation”
in Section 1D (Page 1D-2).
2) Disconnect IAC valve lead wire connector at IAC
valve (1).
