MAP Sensor InspectionS7RS0B1306002
1) Remove air cleaner assembly.
2) Disconnect connector from MAP sensor.
3) Remove MAP sensor.
4) Arrange 3 new 1.5 V batteries (2) in series (check that total voltage is 4.5 – 5.0 V) and connect its 
positive terminal to “Vin ” terminal of sensor and 
negative terminal to “Ground” terminal. Then check 
voltage between “Vout” and “Ground”. Also, check if 
voltage reduces when vacuum is applied up to 400 
mmHg by using vacuum pump (3).
If check result is not satisfactory, replace MAP 
sensor (1).

Electric Throttle Body Assembly On-Vehicle 
Inspection
S7RS0B1306003
WARNING! 
Never touch throttle valve with finger while 
ignition switch is turned ON and accelerator 
pedal is depressed. Otherwise, injury may 
result by pinching the finger between throttle 
valve and throttle body housing.
 
CAUTION! 
• Do not disassemble electric throttle body  assembly.
• Do not expose electric throttle body  assembly to excessive shock like a 
dropping it. If electric throttle body 
assembly has been exposed to excessive 
shock, it should  be replaced.
• Be careful not to accurate a foreign  material (like dust and/ or metallic particle) 
to the throttle body housing and/or throttle 
valve.
Otherwise, the throttle body assembly is 
breaking down by throttle valve accretion.
• Do not apply excessive moving force to  throttle valve for thro ttle valve operation 
check and/or TP sensor performance 
check.
Otherwise, the throttle body assembly is 
breaking down by damaging the internal 
resinous gear of throttle valve actuator.
 
NOTE
After replacing electric throttle body 
assembly, perform calibration of electric 
throttle body assembly referring to “Electric 
Throttle Body System Calibration”.
 
Throttle Valve Visual Check
1) Remove air cleaner outlet hose.
2) Check that there isn’t any foreign matter caught  between throttle valve and throttle body housing. If 
there is, take it out after removing throttle body 
referring to “Electric Th rottle Body Assembly 
Removal and Installation  in Section 1D” and clean 
inside of throttle body thoroughly.

For example of intake side:
When thickness of removed shim is 2.40 mm (0.094 
in.), and measured valve clearance is 0.45 mm 
(0.018 in.).
A = 2.40 mm (0.094 in.) + 0.45 mm (0.018 in.) – 0.20 
mm (0.008 in.) = 2.65 mm (0.104 in.)

Valves and Valve Guides InspectionS7RS0B1406026
Valve Guide
Valve stem-to-guide clearance
Using a micrometer and bore gauge, take diameter readings on valve stems and guides to check stem-to-guide 
clearance.
Be sure to take reading at more than one place along the length of each stem and guide.
If clearance exceeds limit, replace valve and valve guide.
Valve stem and valve guide specification
Valve stem end deflection
If bore gauge is not available, check end deflection of 
valve stem with a dial gauge instead.
Move stem end in directions (1) and (2) to measure end 
deflection.
If deflection exceeds its limit, replace valve stem and 
valve guide.

Visual inspection
• Remove all carbon from valves.
• Inspect each valve for wear, burn or distortion at its 
face and stem end, as necessary, replace it.
• Inspect valve stem end face for pitting and wear. If  pitting or wear is found there, valve stem end may be 
resurfaced, but not too much to grind off its chamber. 
When it is worn out too much that its chamber is gone, 
replace valve.
