P0ACE Fault Code

Hybrid Battery Temperature Sensor "C" Circuit Intermittent/Erratic

• What does that mean?
• Symptoms
• Causes
• Solutions

• The Hybrid Battery Temperature Sensor "C" Circuit is responsible for monitoring the temperature of the hybrid battery pack.
• An intermittent or erratic connection can lead to inaccurate temperature readings, affecting the performance of the hybrid system.
• This fault code indicates that the vehicle's computer has detected a problem with the sensor or its circuit.
• Common causes may include wiring issues, faulty sensors, or connector problems.

What are the symptoms of the P0ACE code?

• Warning lights on the dashboard, particularly the hybrid system light.
• Degraded performance or efficiency of the hybrid system.
• Possible overheating of the hybrid battery, leading to potential safety risks.
• Erratic behavior in the vehicle's power delivery and energy management systems.

What causes the P0ACE code?

• Damaged wiring or connectors in the temperature sensor circuit.
• A malfunctioning temperature sensor that fails to provide consistent readings.
• Electrical interference or short circuits affecting sensor performance.
• Poor ground connections may also contribute to erratic sensor signals.

How to fix P0ACE?

• Inspect the wiring and connectors for any visible damage or corrosion.
• Test the hybrid battery temperature sensor to ensure it is functioning properly; replace if necessary.
• Clean any corrosion from connectors and ensure proper grounding.
• Use a diagnostic tool to clear fault codes and monitor for reoccurrence.
