to the test coupler.
Dry cells negative end → 1
Dry cells positive end → 2
• Connect the digital multi meter to the test cou-
pler.
Digital multi meter negative lead → 1
Digital multi meter positive lead → 3
• Measure the voltage A.
NOTE:
When measuring the voltage A be sure that the
test coupler is connected to the throttle position
sensor.
• Calculate the specified voltage B.
Specified voltage B = Voltage A × (0.136)

• Loosen the throttle position sensor bolt 4.
• Connect the digital multi meter to the test cou-
pler.
Digital multi meter negative lead → 1
Digital multi meter positive lead → 3
• Adjust the throttle position sensor position to
