P2E95: Charge Port Door B Open Request Switch Circuit Low

What it means

The charge port door B open request switch reports a circuit low condition. Operator request for charge port unlocking is unreliable.

At a glance

• Usually lights the check-engine light

How it works

Door B’s open-request switch signals the charging system controller when the driver asks to open that charge-port door. P2E95 sets when the controller detects the switch circuit signal below its expected range, so it may not recognize the request.

Common causes

Most likely first.

1. Switch failed
2. Wiring fault
3. Connector pins corroded - high contact resistance

Symptoms

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

How to diagnose it

1. Check freeze-frame data and live switch status, then operate Door B’s request and note whether the input remains low instead of changing state.
2. Inspect the switch wiring for a short to ground, pinched insulation, or damage near the door and connector.
3. Check the switch connector for corrosion, moisture, loose terminals, or poor contact that could pull the signal low.
4. Test the switch and circuit for continuity and shorts, following the wiring diagram and manufacturer’s specification.
5. If the wiring and switch pass, check the controller input and its grounds before condemning the controller.

Common fixes

• Clean corroded terminals and restore a secure connector fit.
• Repair a signal wire shorted to ground or other damaged wiring.
• Replace a failed Door B open-request switch.
• Repair a verified controller connection or input fault.

Can I keep driving?

Driving is generally possible if the vehicle has no other warnings, but the Door B release request may not work and charging may fail to start or stop unexpectedly. Keep enough range for another charging option and do not force the door.
