TPS (THROTTLE POSITION SENSOR) SYSTEM
ELEC
7. Adjust:
9
Idle speed for TPS adjustment
8. Disconnect the TPS coupler.
9. Calculate:
9
TPS coil resistance at idle speed.
<Example>
If the TPS coil resistance is 5k
Ω
, then the TPS
coil resistance at idle speed is:
5k
Ω ×
(0.13~0.15) = 650~750
Ω
Refer to “TPS COIL INSPECTION” section
about the TPS coil resistance.
10. Adjust:
9
TPS coil resistance at idle speed
Idle speed for TPS adjustment:
1,700~1,900 rpm
Adjustment steps:
9
Set the inductive tachometer (engine
tachometer) to the high tension cord.
9
Turn the throttle stop screw
1
until the
specified idle speed.
Refer to “IDLE SPEED ADJUSTMENT” sec-
tion in the CHAPTER 3.

Adjustment steps:
Adjust the angle of the TPS

to obtain the
resistance calculated (example: 650~750
Ω
).
