THROTTLE POSITION SENSOR SYSTEM
4. Install:
Throttle position sensor coupler
G
5. Adjust:
Engine idling speed
G
Refer to "ENGINE IDLING SPEED
ADJUSTMENT" section in the CHAP-
TER 3.
6. Insert the thin electric conductors 2
(lead) into the throttle position sensor
coupler 1, as shown, and connect the
tester to them.
Tester (+) lead → Yellow lead 3
Tester (–) lead → Black lead 4
CAUTION:
Do not insert the electric conductors
G
more than required because it may
reduce the waterproof function of the
coupler.
Make sure that a short-circuit does not
G
develop between the terminals because it
may cause damage to electrical compo-
nents.
7. Start the engine.
8. Adjust:
Throttle position sensor output voltage
G
Adjustment steps:
Adjust the installation angle of the throttle
position sensor 1 to obtain the specified out-
put voltage.
NOTE:
Measure the output voltage accurately with a
digital electronic voltmeter that gives an easy
reading of a small voltage.

tion sensor out-
put voltage
