SEAL GP-CRANKSHAFT 7E7589 - Caterpillar

System Operation Description:The analog sensor supply provides power to all analog sensors. The Electronic Control Module (ECM) supplies 5.0 0.2 VDC from the ECM connector J1/P1 to each analog sensor connector. The sensor return line connects to the ECM connector J1/P1. The analog sensor supply is output short circuit protected. A short circuit to the battery will not damage the circuit inside the ECM.Note: The analog sensors are not protected from overvoltage. A short from the analog supply line to the +Battery supply may damage the sensors. If CID-FMI 262-03 is logged, it is possible that all of the analog sensors have been damaged. Repair the analog sensor supply and check for any "ACTIVE" sensor diagnostic codes in order to determine if a sensor has failed.Note: The engine monitoring system may be programmed by dealers and/or customers in some instances. Dealers and/or customers can monitor customized warnings, derates, shutdown override setpoints, and delay times using the Caterpillar Electronic Technician (ET). Customized parameters may affect the behavior of the ECM. The behavior of the ECM may vary from the description that is given in this system operation section. You may refer to Troubleshooting, "Engine Monitoring System" in order to determine if there are any parameters that are affecting engine operation.The following list contains a description of the analog sensors that are found on the engine.Aftercooler Temperature Sensor - The ECM uses the signal from the sensor to monitor changes in system temperature. The ECM makes adjustments to the system's operating parameters as the temperature changes. This allows the engine to operate at optimal performance through a wide range of operating temperatures. The operating range of the sensor is −40 °C to 120 °C (−40 °F to 248 °F). If the value is not in this range, the previous
