The P0ACE fault code refers to a problem with the HybridEV Battery Temperature Sensor 3 Circuit. This sensor is responsible for monitoring the temperature of the battery in hybrid or electric vehicles. It is located within the battery sections and there are two temperature sensors in each section. The sensor works by measuring the resistance of the battery cell group, which changes with temperature.

As the temperature decreases, the sensor resistance increases, and as the temperature increases, the sensor resistance decreases. The HybridEV interface control module supplies 5V to the signal circuit and acts as a ground for the low reference circuit. The HybridEV Powertrain Control Module uses the temperature sensor values to determine the battery module temperature and control the battery cooling system. If the hybrid battery temperature sensor is intermittent or has changed by 10°C (18°F) or more for 4 out of 5 seconds, the Diagnostic Trouble Code (DTC) will be set, indicating a problem with the sensor circuit.

What are the possible causes for the automobile fault code p0ace?

If you see the engine light on or the service engine soon warning light, the fault code P0ACE could be the culprit. This code is often caused by a faulty Hybrid/EV Battery Assembly, an open or shorted harness, a poor electrical connection in the Hybrid/EV Battery Assembly circuit, or a faulty Hybrid/EV Battery Interface Control Module. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to also check the possible causes listed above.

How can I visually inspect the wiring harness and connectors to fix the p0ace fault code?
