This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the way it measures the battery's voltage in a hybrid or electric vehicle. It's like if your remote control couldn't tell how much battery power it has left.
The P0B96 code is triggered when the powertrain control module (PCM) detects a voltage reading from the battery voltage sense circuit that is outside the normal range.
The P0B96 code indicates that the voltage sense circuit associated with the hybrid or electric vehicle's battery is reporting a value that is not within the expected range. This could be due to a faulty sensor, wiring issues, or a problem with the battery itself.
• Check Engine Light illuminated
• Reduced fuel efficiency
• Possible battery charging issues
• Faulty battery voltage sensor
• Damaged or corroded wiring/connectors
• Battery pack issues
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the battery voltage sensor and related wiring for damage.
• Test the battery voltage sensor for proper operation.
• Replace the faulty battery voltage sensor.
• Repair or replace damaged wiring/connectors.
• Check and service the battery pack if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools
$150 - $500
Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance of the battery system
• Ensure all electrical connections are clean and secure
• Monitor battery health regularly
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you are not familiar with hybrid systems.
Check with the vehicle manufacturer for specific warranty coverage on hybrid/EV components.
This code is relatively common in hybrid and electric vehicles as they rely heavily on battery management systems.
Moderate – It should be addressed soon to avoid potential battery performance issues.
Driving with a malfunctioning battery system can lead to reduced performance and efficiency.
• Vehicle in 'Ready' mode
• Battery at normal operating temperature
The battery voltage sensor is typically located near the hybrid or EV battery pack.
Q: Can I drive with a P0B96 code?
A: It's possible to drive, but it's not recommended as it may affect vehicle performance and efficiency.
Q: How do I reset the P0B96 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnosis is needed.
