Compensation Sensor Short

Compensation Sensor Short
The ambient-compensation sensor (NTC) on the LPM board in the quaternary
pump has failed (short circuit).
The resistance across the temperature compensation sensor (NTC) on the
LPM board is dependent on ambient temperature. The change in resistance is
used by the leak circuit to compensate for ambient temperature changes. If
the resistance across the sensor falls below the lower limit, the error message
is generated.
• Defective LPM board.
❏ Exchange the LPM board.
