Hybrid Battery Voltage Sense Circuit Low
The P0B60 code indicates that the hybrid battery voltage sense circuit is reading a voltage lower than expected. This circuit monitors the voltage of the hybrid battery pack. A low voltage reading can be caused by a faulty battery voltage sensor, wiring issues, or a weak hybrid battery. This condition can affect the hybrid system's ability to charge and discharge properly, potentially leading to reduced fuel economy or loss of hybrid functionality.
01. Most Common Causes
- Faulty hybrid battery voltage sensor
- Damaged or corroded wiring/connectors in the voltage sense circuit
- Weak or failing hybrid battery pack
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced fuel economy
- Hybrid system warning light on
- Loss of electric power assist
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Visually inspect the hybrid battery voltage sensor and its wiring for damage, corrosion, or loose connections.
Step 3: Test the voltage sensor output using a multimeter and compare to manufacturer specifications.
Step 4: If sensor and wiring are okay, perform a hybrid battery capacity test to check for weak cells.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as it can lead to further hybrid system damage or complete loss of hybrid function. Have the vehicle inspected as soon as possible.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and sensor replacement, but if the hybrid battery needs replacement, costs can be much higher.
