PACCAR PX-6 CM2150 (2007-09) Fault Code: 196 (3 wire sensor) PID: 111 SPN: 111 FMI: 4 Coolant Level Sensor 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at engine coolant level circuit.

Verify the ECM calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM.

Possible causes:

1)Open signal circuit in the engine harness, connectors, or sensor
2)Signal circuit shorted to ground in the engine harness, connector, or sensor
3)Damaged sensor.

Possible repairs:

1)Replace the engine coolant level sensor.
2)Repair or replace the OEM harness.
3)Replace the ECM.
