THROTTLE POSITION SENSOR CHECK

Equipment
side connector
1. Disconnect the throttle position sensor connector.
2. Measure the resistance between the throttle position
3. Measure the resistance between the throttle position
4. If the resistance is outside the standard value, or if it doesn't
temperature sensor immersed in hot water, check
resistance.
Standard value:
2.1 – 2.7 kΩ (at 20 C)
0.26 – 0.36 kΩ (at 80 C)
replace the sensor.
Specified sealant:
3M NUT Locking Part No.4171 or equivalent
it to the specified torque.
Tightening torque: 29 Nm
sensor side connector terminal 1 and terminal 4.
Standard value: 3.5–6.5 kΩ
sensor side connector terminal 2 and terminal 4.
Normal condition:
Throttle valve slowly open
until fully open from the idle
position
change smoothly, replace the throttle position sensor.
NOTE
For the throttle position sensor adjustment procedure, refer
to P.13B-65.
