THROTTLE POSITION SENSOR SYSTEM
THROTTLE POSITION SENSOR
REPLACEMENT AND ADJUSTMENT
1. Remove:
●
Throttle position sensor coupler
●
Screw (throttle position sensor)
1
●
Washer
2
●
Throttle position sensor
3
NOTE:
Loosen the screws (throttle position sensor)
using the T20 bit (tamper resistant fastener
type).
2. Replace:
●
Throttle position sensor
3. Install:
●
Throttle position sensor
1
●
Washer
2
●
Screw (throttle position sensor)
3
NOTE:
●
Align the slot
a
in the throttle position sen-
sor with the projection
b
on the carburetor.
●
Temporarily tighten the screws (throttle posi-
tion sensor).
4. Adjust:
●
Engine idling speed
Refer to “ENGINE IDLE SPEED
ADJUSTMENT” section in the CHAP-
TER 3.
5. Calculate:
●
Throttle position sensor coil resistance
at idle speed
<Example>
If the throttle position sensor coil resistance is
5 k
Ω
, then the throttle position sensor coil
resistance at idle speed is:
5 k
Ω
×
(0.13 ~ 0.15) = 650 ~ 750
Ω
Refer to “THROTTLE POSITION SEN-
SOR COIL INSPECTION” section
about the throttle position sensor coil
resistance.
Throttle position sensor coil resistance
at idle speed:
Throttle position sensor coil resis-
tance
×
(0.13 ~ 0.15)
