This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the battery voltage is too low, which might be a mistake. Imagine if your toy's battery meter said it was empty, but you just put in new batteries.
The vehicle's control module has detected an implausibly low voltage reading from the Hybrid/EV Battery Voltage Sense 'A' Circuit.
The P1B92 code indicates that the voltage reading from the battery voltage sense circuit 'A' is lower than expected. This could be due to a fault in the voltage sensor, wiring issues, or a problem with the battery itself. The vehicle's control module uses this sensor to monitor the battery's state of charge and health.

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect battery connections.
• Perform routine battery maintenance.
• Ensure proper charging habits.
Sensor Issue
• Avoid driving the vehicle until the issue is diagnosed.
• Consult a professional mechanic for accurate diagnosis.
• Do not attempt complex repairs without proper tools and knowledge.
Check with the vehicle manufacturer for warranty coverage on hybrid/EV components.
This code has been more prevalent with the increased use of hybrid and electric vehicles, highlighting the importance of battery management systems.
High – This issue can affect the vehicle's performance and efficiency, and should be addressed promptly.
Driving with this code may result in reduced performance and efficiency. It is advisable to address the issue to ensure safety and compliance with emission standards.
• Vehicle in 'ON' position
• Battery fully charged
The battery voltage sensor is typically located near the hybrid/EV battery pack, often in the rear of the vehicle.
Q: Can I drive my car with a P1B92 code?
A: It's not recommended to drive with this code active, as it may affect your vehicle's performance and efficiency.
Q: How do I clear a P1B92 code?
A: After repairs, you can clear the code using an OBD-II scanner, but ensure the issue is resolved to prevent it from returning.
