How to Fix Code P0ACA

Check the “possible causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

P0ACA Possible Symptoms

Check engine light illuminated (or service engine soon warning light)

P0ACA Meaning

Battery temperature sensors are provided at 3 locations in the HV battery. The thermistor resistance, built into each battery temperature sensor, varies according to changes in HV battery temperature. The lower the battery temperature, the higher the thermistor resistance. Conversely, the higher the temperature, the lower the resistance. The battery intelligent unit uses the battery temperature sensors to detect HV battery temperature and sends the detected value to the power management control ECU. Based on the detection results, the power management control ECU controls the fan motor. (The fan motor starts when the HV battery temperature exceeds a predetermined level.)
