P1A23: Your Car’s Battery Needs Attention
The P1A23 code is related to the Hybrid Battery 1 Circuit High Voltage. Battery voltage sensors are used to monitor the voltage of the batteries in the Energy Storage Box (ESB). The ESCM monitors the voltage drop across the battery voltage sensors and uses the inputs for hybrid calculations.
When the battery voltage is high, the resistances of the sensors are high and the voltage signals are high. When the battery voltage is low, the resistances of the sensors are low and the voltage signals are low.
