Brake Accumulator Oil Pressure Sensor
Illustration 1 g03558616
Location of the brake accumulator oil pressure sensor
(1) Brake accumulator oil pressure sensor The brake accumulator oil pressure sensor is located on the accumulator charging valve. The accumulator charging valve is located on the left side of the front frame, in the transmission compartment.When the machine is started, brake accumulator oil pressure increases. The Power Train/Chassis ECM will sense, through the brake accumulator oil pressure sensor, when pressure reaches 8275 kPa (1200 psi). The Power Train/Chassis ECM receives this signal and will allow the parking brake to be disengaged.

Caterpillar Monitoring system display
(2) Brake accumulator oil pressure alert indicator When, the pressure increases to 9500 kPa (1380 psi) the Power Train/Chassis ECM receives a signal from the brake accumulator oil pressure sensor. The Power Train/Chassis ECM then sends a signal to the Caterpillar Monitoring System over the CAT Data Link. The Caterpillar Monitoring System will then turn off brake accumulator oil pressure alert indicator (2) on the Caterpillar Monitoring System display.If, brake accumulator oil pressure decreases to 8300 345 kPa (1200 50 psi) the Power Train/Chassis ECM receives a signal from the brake accumulator oil pressure sensor and sends this signal to the Caterpillar Monitoring System. The Caterpillar Monitoring System will activate alert indicator (2).If machine operation is continued and brake accumulator oil pressure decreases to 6890 345 kPa (1000 50 psi), the Power Train/Chassis ECM receives a signal from the brake accumulator oil pressure sensor and automatically engages the parking brake.Once the parking brake has been engaged, the parking brake will remain engaged until the brake accumulator oil pressure rises above 8270 kPa (1200 psi). The operator must then cycle the parking brake switch from the ON position to the OFF position in order to disengage the parking brake.Reference: For further information on the brake accumulator oil pressure sensor, refer to Power Train Electronic Control System, Systems Operation, Troubleshooting, Testing and Adjusting, "Sensors", for the machine that is being serviced.Transmission Oil Pressure Sensor (If Equipped)

Location of the transmission oil pressure sensor
(3) Transmission oil pressure sensor Transmission oil pressure sensor (3) is located on the right side of the transmission. The oil pressure sensor senses the oil pressure in the transmission hydraulic system. The oil pressure sensor sends a signal to the Power Train/Chassis ECM.

Caterpillar Monitoring System display
(4) Transmission oil pressure alert indicator During normal machine operation, the transmission oil pressure will be 2690 to 3205 kPa (390 to 465 psi). The Power Train/Chassis ECM will sense this pressure through oil pressure sensor (3). If the transmission oil pressure decreases to 1725 kPa (250 psi), the Power Train/Chassis ECM will send a signal over the CAT data link to the Caterpillar Monitoring System. The Caterpillar Monitoring System will then activate transmission oil pressure alert indicator (4) on the Caterpillar Monitoring System display. The alert indicator will remain activated until the pressure rises above 1725 kPa (250 psi).If machine operation is continued and transmission oil pressure decreases below
