Code P1FFD Saturn Description

The hybrid/EV battery pack coolant system has a level sensor. The hybrid/EV battery pack coolant level sensor is attached to the coolant surge tank. The level sensor is a 2 state bi-metallic reed switch which changes state when the switch reed is exposed to magnetism. The level of the hybrid/EV battery pack coolant in the surge tank causes a magnet-equipped float to move towards and away from the sensor as coolant level decreases or increases. The hybrid/EV powertrain control module 2 supplies 5 V to the signal circuit and a ground for the low reference circuit. The hybrid/EV battery pack coolant level sensor resistance decreases when the battery coolant level in the surge tank gets low. The hybrid/EV powertrain control module 2 uses the hybrid/EV battery pack coolant level sensor to determine if the hybrid/EV battery pack coolant system is low on coolant.
