connector: between head cover and fil-
ter box on left side (3-ways white con-
nector).
Electrical characteristics:
PIN 64: gear indication: closed circuit (continuity);
gear engaged: open circuit (infinite resistance).
Gear engaged circuit resistance: 1st gear: 0.8
kohm, 2nd gear 0.5 kohm, 3rd gear 15.0 kohm, 4th
gear 6.9 kohm, 5th gear 2.8 kohm, 6th gear 1.5
kohm.
Pin out:
white/black: ground from ECU, light blue: + 12V
from ECU (gear), pink: + 5V from ECU (gears).

BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING

NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSIS INSTRUMENT: STATUSES
Gearbox in neutral
•
Yes/No
Gear engaged: 0 - 1 - 2- 3 - 4 - 5 - 6
DIAGNOSIS INSTRUMENT: ELECTRICAL ERRORS
Gear sensor P0461
•
shorted to positive or open circuit / shorted to negative.
Error cause
•
If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 72. If
shorted to negative: voltage equal to zero has been detected at PIN 72.
Troubleshooting
•
If the circuit is open, shorted to positive: the error is detected with gear engaged only. Check
the sensor connector and the VEHICLE connector of the control unit: if not OK, restore; if
they are OK, check the continuity of the grey/black cable between the two connectors: if not
OK, restore; if they are OK, with key set to ON and control unit connector disconnected,
check from the control unit side if the cable is in voltage: if it is in voltage, disconnect the
sensor connector and check if the cable is in voltage: if it is in voltage, restore the cable
harness; if it is not in voltage, replace the sensor (there is an interruption or shorted to positive
of the pink cable in the section from the sensor connector to the sensor or inside the sensor).
•
If shorted to negative: disconnect the sensor connector and with key set to ON, check grey/
black cable voltage: if equal to zero, restore the cable harness; if equal to approx. 5 V,
