Case IH 2162 (519176.03) - DEC – DEC: Synchro Low-mid Range Position Sensor short to high voltage

The Synchro Low-mid Range Position Sensor is experiencing a short to high voltage (FMI 3), indicating the signal circuit is reading a voltage value out of the normal operating range. This points to a short to the power supply, loss of sensor ground, or internal failure of the potentiometer.

1. 1

   Use the tractor's instrument cluster (ICU) or EST diagnostic software to monitor the sensor's output voltage

2. 2

   Check the wiring harness for shorts to the power supply

3. 3

   Verify the sensor's ground connection before condemning the sensor
