Fuel pressure sensor
Engine oil pressure sensor
Atmospheric pressure sensor
Exhaust temperature tensor
Intake manifold pressure sensorThe supply voltage is routed to terminal 1 of each sensor connector. The sensor return is routed to terminal 2 of each sensor connector. For the pressure sensors, the sensor signal is routed to terminal 3 of each sensor connector. The sensor signal for the exhaust temperature sensors is routed to terminals 3 and 4 of the connector for the sensor buffer.The ECM provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.Diagnostic Testing using Caterpillar Electronic Technician (ET)Wiggle Test - The wiggle test allows the technician 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.
