TPS (THROTTLE POSITION SENSOR) SYSTEM
4. Adjust:
Idle speed
G
Adjustment steps:
Attach the inductive tachometer (engine
G
tachometer) to the high tension cord.
Turn the throttle stop screw 1 until the
G
specified idle speed.
Refer to "IDLE SPEED ADJUSTMENT"
section in the CHAPTER 3.
Idle speed:
1,700 ~ 1,900 r/min
5. Insert the thin electric conductors 2
(lead) into the TPS 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 dose not
G
develop between the terminals because it
may cause damage to electrical compo-
nents.
6. Start the engine.
7. Adjust:
TPS output voltage
G
Adjustment steps:
Adjust the installation angle of the TPS 1 to
obtain the specified output voltage.
NOTE:
Measure the output voltage accurately with
a digital electronic voltmeter that gives an
easy reading of a small voltage.
