Three different types of pressure sensors are found on this engine.The first type of sensor found is commonly seen on other Cat applications which is a 3 wire analog, active pressure sensor.The second type of sensor found is another 3 wire analog, active pressure sensor, 439-4065 Sensor, used for a fuel rail pressure measurement. The wiring to this sensor varies from the typical 3 wire pressure sensors found elsewhere on the engine.
Terminal 1: Sensor Ground
Terminal 2: Sensor Signal
Terminal 3: Sensor Supply VoltageThe third type of sensor found on the engine is a combination pressure and temperature sensor. This sensor is a 4 wire sensor that has a common power supply and ground with two independent signal wires, one for pressure feedback and one for temperature feedback.
Terminal 1 : Sensor Ground
Terminal 2: Temperature Signal
Terminal 3: Sensor Supply Voltage
Terminal 4: Pressure SignalThe supply voltage is routed to terminal 1 of each sensor connector. The sensor return is routed to terminal 2 of each sensor connector. The sensor signal is routed to terminal 3 of each sensor connector. The Electronic Control Module (ECM) provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.Diagnostics on the Cat® Electronic Technician (ET)Wiggle Test - The Wiggle Test allows you to monitor the status of the signals from the sensors.For additional information regarding the Wiggle Test, refer to the documentation that accompanies the Cat ET software.
