This summary uses the existing diagnostic information shown in full below.
The car's battery charger isn't giving enough power, like a phone charger that's too weak to charge your phone.
This code indicates that the voltage output from Battery Charger B is below the expected level.
The P2E3B code is set when the Powertrain Control Module (PCM) detects that the output voltage from Battery Charger B is below the manufacturer's specified threshold. This can affect the charging system's ability to maintain the battery's state of charge.
• Battery warning light on
• Battery not charging properly
• Electrical accessories not functioning correctly
• Faulty battery charger
• Poor electrical connections
• Damaged wiring or connectors
PCM: Powertrain Control Module
Voltage: The electrical potential difference between two points
• Check for any loose or corroded connections at the battery charger.
• Test the output voltage of Battery Charger B.
• Inspect wiring and connectors for damage or corrosion.
• Tighten or clean all electrical connections.
• Replace faulty battery charger.
• Repair or replace damaged wiring or connectors.
• Multimeter
• Wrench set

Moderate
• Chevrolet Volt
• Toyota Prius
• Nissan Leaf
• Regularly check battery connections.
• Ensure battery charger is functioning properly.
• Perform routine maintenance on the charging system.
Electrical System Issue
• Do not ignore the battery warning light.
• Schedule a diagnostic check if the problem persists.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been reported in hybrid and electric vehicles where maintaining battery charge is critical.
Moderate – Addressing this issue promptly can prevent further battery or electrical problems.
Driving with a malfunctioning battery charger can lead to vehicle breakdowns. Ensure repairs are conducted by a qualified technician.
• Vehicle in 'On' position
• Battery charger connected
Battery Charger B is typically located near the vehicle's battery or integrated within the battery management system.
Q: Can I drive my car with this code?
A: It's not recommended, as the battery may not charge properly, leading to potential breakdowns.
Q: How do I know if my battery charger is faulty?
A: A multimeter can be used to check the output voltage. If it's below the specified range, the charger may be faulty.
