This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a sensor in an electric or hybrid car's battery. The sensor checks how thick the battery cells are, and it's not working right.
The P2E73 code is triggered when the vehicle's onboard computer detects an issue with the performance of the cell thickness sensor circuit in the battery pack B of a hybrid or electric vehicle.
The cell thickness sensor is responsible for monitoring the physical thickness of the battery cells in the battery pack. This information is crucial for ensuring the battery's health and performance. A fault in the sensor circuit can lead to incorrect readings, potentially affecting the battery's operation.
• Check Engine Light is on
• Reduced battery performance
• Possible vehicle power limitations
• Faulty cell thickness sensor
• Damaged wiring or connectors in the sensor circuit
• Malfunctioning battery management system
OBD-II: On-Board Diagnostics, a standardized system in vehicles for self-diagnosing and reporting.
Battery Management System: A system that manages the battery's operation and health in electric and hybrid vehicles.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors related to the sensor for damage.
• Test the cell thickness sensor for proper operation.
• Replace the faulty cell thickness sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the battery management system if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks on the battery system
• Ensure proper handling of the battery pack
• Avoid extreme temperatures that can affect battery health
Sensor Issue
• Avoid driving the vehicle aggressively until the issue is resolved.
• Schedule a service appointment with a qualified technician.
Check with your vehicle manufacturer as battery components may be covered under warranty.
This code has become more common as hybrid and electric vehicles have increased in popularity, highlighting the importance of battery health monitoring.
Moderate – It is important to address this issue to maintain battery health and vehicle performance.
Ignoring this issue could lead to reduced vehicle performance and potential safety hazards. Always consult a professional for repairs.
• Vehicle must be in a safe, stationary position.
• Battery system should be cool and not under load.
The cell thickness sensor is located within or near the battery pack, typically in the vehicle's rear or undercarriage.
Q: Can I drive with the P2E73 code?
A: It's not recommended to drive long distances with this code, as it can affect battery performance.
Q: How do I reset the P2E73 code?
A: After repairs, the code can be cleared with an OBD-II scanner. However, ensure the issue is fixed first.
