It this error persists, use a pressure gauge to check the pressure of the oil in the engine
circuit
Neutral sensor
Function
it tells the gear position to the control unit: in neutral or in gear.
Operation / Operating principle
for gear in neutral, the circuit is closed to ground connection: then, via CAN, the control unit sends the
signal to the instrument panel which turns on the neutral speed warning light.
Level in electrical circuit diagram:
start-up enabling switches
Location:
•
Sensor: rear / upper side of the gearbox
•
Connector: on the sensor
Electrical characteristics:
•
Gear in neutral: closed circuit (0 V on wire from control unit to sensor / switch in continuity).
•
Gearshift engaged: open circuit (12 V on wire from control unit to sensor / open switch,
infinite resistance)
Pin-out:
•
PIN 1: Voltage 12V
NAVIGATOR: STATUSES
Gear in neutral
Example value:
yes/no
DIAGNOSIS
•
Indication on the instrument panel always gear engaged: check the control unit connector
and the sensor connector: if they are not OK, restore the cable harness; if OK, disconnect
the connector and, with gear in neutral, check continuity to ground of the terminal, sensor
side: if there is not continuity, replace the sensor (after checking cable harness continuity
on the sensor side and the correct mechanical position); if there is, check cable continuity
between the sensor connector and PIN 23 of the BROWN connector: if there is no continuity,
restore the cable harness. If there is, replace the instrument panel if the vehicle performance
is correct (the engine starts with gear in neutral but the neutral warning light is off) or replace
the control unit if the vehicle performance is not correct (the engine does not start with gear
in neutral).
•
Indication on the instrument panel always gear in neutral: disconnect the terminals from the
sensor and check if there is continuity with ground connection at PIN toward the sensor, with
gear engaged: if there is continuity, replace the sensor. If it is ground insulated, it means
