P0E2E: Battery Charger A Fuse

What it means

The battery charger A fuse circuit indicates an open or blown fuse, which can interrupt the associated charger circuit.

At a glance

• Usually lights the check-engine light
• The engine or gearbox may go into limp mode

How it works

Battery charger A's fuse protects the associated charging circuit and is monitored for continuity. P0E2E indicates that the fuse path is open, so charger A may not operate or may stop charging; a fuse can open because of a downstream short.

Common causes

Most likely first.

1. Fuse blown by short circuit
2. Downstream short circuit

Symptoms

• Charge status indicator shows fault
• Charging may not start or interrupts
• Slower-than-expected charge rate

How to diagnose it

1. Save any charging fault data and confirm whether charging fails to start or stops, noting whether the fault occurs with charger A's circuit.
2. With the vehicle and charging equipment safely isolated according to the manufacturer's instructions, locate and visually inspect the battery charger A fuse.
3. Test the fuse for continuity using the specified service procedure rather than relying on appearance alone.
4. If the fuse is open, inspect the charger A wiring and connected components for a short before fitting a replacement.
5. After repairing any downstream fault, install only the specified fuse type and verify charger A operation.

Common fixes

• Replace an open battery charger A fuse with the specified type after checking for a downstream short.
• Repair damaged or shorted wiring in the charger A circuit.
• Repair a faulty downstream charger component causing the fuse to open.
• Repair the fuse holder or connections if they prevent reliable continuity.

Can I keep driving?

The vehicle may remain drivable, but charging can fail or be interrupted, reducing available electric range. Do not keep replacing a fuse that opens again; a continuing fault can interrupt charging or damage the circuit.
