199001808 - 2127OP OIL PRESSURE SENSOR OPERATION CHECK (Robotized gearbox)

STEP	CHECK TO BE PERFORMED	REMEDIAL ACTION IF THE CHECK IS NOT OK
1	Sensor power supply checkTurn the key to the MAR positionWith the Examiner in the voltmeter mode check that the voltage between pins A and B is around 5 Volt.	Restore the correct wiring between the gearbox control unit and the sensor    See E7051 ROBOTIZED GEARBOX
2	Check the sensor signal. Turn the key to the ON position. Using the Examiner, check in voltmeter mode that the voltage between pins B and C is 0.4 Volt (circuit vacuum) and 4.8 (circuit pressurized).	Restore the continuity/insulation of the wiring between the gearbox control unit and the sensor.    See E7051 ROBOTIZED GEARBOX Replace the pressure sensor    Op. 2127E50 HYDRAULIC SELECTION GEARBOX CIRCUIT PRESSURE SENSOR - R.R. If everything is OK, replace the robotized gearbox control unit    Op. 2127E10 HYDRAULIC SPEED SELECTION SYSTEM CONTROL UNIT - R.R.
