This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the sensor that checks the voltage coming into the car's battery charger. It's like when a toy's battery charger isn't working right because it can't tell how much power it's getting.
The P0E8B code is triggered when the vehicle's computer detects an issue with the input voltage sensor circuit for Battery Charger B. This sensor is responsible for monitoring the voltage level coming into the battery charger.
The Battery Charger B Input Voltage Sensor Circuit monitors the voltage level supplied to the battery charger. If the sensor detects a voltage level that is outside the expected range, the powertrain control module (PCM) will set the P0E8B code. This can be due to a faulty sensor, wiring issues, or problems with the battery charger itself.
• Check Engine Light is on
• Battery not charging properly
• Electrical issues in the vehicle
• Faulty input voltage sensor
• Damaged or corroded wiring/connectors
• Malfunctioning battery charger
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Inspect the wiring and connectors for damage or corrosion.
• Test the input voltage sensor for proper operation.
• Check the battery charger for faults.
• Replace the faulty input voltage sensor.
• Repair or replace damaged wiring/connectors.
• Replace or repair the battery charger.
• Multimeter
• OBD-II scanner
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect battery connections.
• Ensure battery charger is functioning properly.
• Keep wiring and connectors clean and free of corrosion.
Sensor Issue
• If the Check Engine Light is on, have your vehicle inspected by a professional.
• Avoid using the vehicle until the issue is resolved to prevent battery damage.
Check with your vehicle manufacturer to see if the battery or charging system is covered under warranty.
This code has been associated with hybrid and electric vehicles, where battery charging systems are more complex.
Moderate – While the vehicle may still operate, failure to address the issue can lead to battery damage or vehicle stalling.
Driving with a malfunctioning battery charger can lead to electrical failures and should be addressed promptly to ensure vehicle safety.
• Vehicle must be in a safe, stationary position.
• Ensure the battery is not completely discharged.
The input voltage sensor is typically located near the battery charger, often within the engine compartment or under the vehicle.
Q: Can I drive my car with the P0E8B code?
A: It's not recommended to drive the car until the issue is fixed, as it could lead to further damage or leave you stranded.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspection of the battery charging system can help prevent issues related to this code.
