|What is P0AC2 SATURN code meaning?
The hybrid/EV battery current sensor is mounted inside the hybrid/EV battery pack. The positive high voltage cable that goes to the positive contactor relay passes through the hybrid/EV battery pack current sensor. The hybrid/EV battery pack current sensor detects the amperage that flows in and out of the hybrid/EV batteries. The battery energy control module supplies and monitors a 5 V reference signal to the hybrid/EV battery pack current sensor. The hybrid/EV battery pack current sensor returns a signal between 0 and 5 V to the battery energy control module. The hybrid/EV battery pack current sensor signal is in proportion to the amperage going in and out of the hybrid/EV battery pack. A signal voltage of the hybrid/EV battery pack current sensor greater than 2.5 V indicates that the hybrid/EV battery is being charged and a signal voltage less than 2.5 V indicates discharging. The hybrid/EV battery pack current sensor has 2 measurement ranges in order to maintain accuracy. The ranges are low resolution and high resolution. The measurement ranges of the hybrid/EV battery pack current sensor have some overlap with each other. The high resolution measures from -23 to +23 A. The low resolution measures from -470 to +280 A.
