Electrical system
•
connector: between the head cover
and the left side of the filter casing (3
pin white connector).
Electrical specifications:
PIN 64: neutral indication: closed circuit (continu-
ity); gear engaged: open circuit (infinite resist-
ance). Gear 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 (neutral), pink: + 5V from ECU (drive).
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTIC TOOL: STATUSES
Gearbox in neutral
•
Yes/No
gear engaged: 0 - 1 - 2- 3 - 4 - 5 - 6
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
Gear sensor P0461
•
short circuit to positive or open circuit/ short circuit to negative.
Error cause
•
If open circuit, short circuit to positive: excessive voltage has been detected on PIN 72. If
short circuit to negative: voltage equal to zero detected at PIN 72.
Troubleshooting
•
If open circuit, short circuit to positive: the error is detected only with a gear engaged. 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 ok with key ON and control unit connector disconnected, check from the control
unit connector side if the cable is energised: if energised, disconnect the sensor connector
and check if the cable is energised: if it is energised, restore the wiring harness, if it is not
energised, replace the sensor (there is an interruption or a short circuit to positive of the
pink/black cable in the section between the sensor connector and the sensor or inside the
sensor itself).
•
If short circuit to negative: disconnect the sensor connector and with key ON, check the
voltage of the Grey/Black cable: if it is equal to zero, restore the wiring harness, if it is equal
