Checking the gear sensor
– Use a digital multimeter to measure the voltage between the
blue/green cable (neutral) and the ground on connector AM/AR
3
with the cables connected.
Multimeter reading: 0 – 2.5 volts with the transmission in neutral
Multimeter reading: over 2.6 volts with a gear engaged
– Measure the voltage between the gray cable (2nd gear) and the
ground.
Multimeter reading: 0 – 2.5 volts with the transmission in 2nd gear
Multimeter reading: over 2.6 volts with the transmission not in 2nd gear
– Measure the voltage between the yellow/brown cable (3rd gear) and
the ground.
Multimeter reading: 0 – 2.5 volts with the transmission in 3rd gear
Multimeter reading: over 2.6 volts with the transmission not in 3rd gear
