TPS REPLACEMENT AND ADJUSTMENT
1. Remove:
●
TPS coupler
●
Screw (TPS)
1
●
Plain washer
2
●
TPS
3
2. Replace:
●
TPS
3. Install:
●
TPS
1
●
Plain washer
2
●
Screw (TPS)

●
TPS coupler
NOTE:
●
Align the slot
a
in the TPS with the projec-
tion
b
on the carburetor.
●
Temporarily tighten the screws (TPS).
4. Adjust:
●
Idle speed
Refer to “IDLE SPEED ADJUSTMENT”
section in the CHAPTER 3.
5. Calculate:
●
TPS coil resistance at idle speed.
<Example>
If the TPS coil resistance is 5 k
Ω
, then the TPS
coil resistance at idle speed is:
5 k
Ω
×
(0.13 ~ 0.15) = 650 ~ 750
Ω
Refer to “TPS COIL INSPECTION” sec-
tion about the TPS coil resistance.
TPS coil resistance at idle speed:
TPS coil resistance
×
(0.13 ~ 0.15)
