Causes

Short to ground in the charge port door B open-request wiring
Faulty/open or internally shorted charge port door B request switch
Corroded, loose or damaged connector or pin at switch or body control module (BCM)
Water intrusion in connector or wiring harness
Faulty body control module / door controller
Blown fuse or poor ground elsewhere in related circuits

Symptoms

Charge port door B will not open on request or is intermittent
Dash message or instrument cluster indicator related to charge port door
DTC P2E95 stored; may illuminate a fault indication
Vehicle may not allow charging if charge door cannot be commanded open
Operation may be intermittent or only work when manipulating harness/switch

What to check

Read and record freeze-frame and live data with a scan tool; confirm P2E95 is current or historic
Visually inspect switch, charge port door mechanism, connectors and wiring for damage, corrosion or moisture
Check for related DTCs (communication or other door/lock codes)
Verify fuses and main power/ground for BCM or door controller
Backprobe the switch connector and BCM input with a multimeter while operating the switch
Perform wiggle test on harness while monitoring signal to reproduce fault

Signal parameters

Inactive (no open request): circuit expected HIGH — approx. battery voltage (≈11–15 V on 12 V systems) when pulled up by module
Active (open request): switch typically pulls the circuit LOW — approx. 0–1 V when closed to ground
Short-to-ground condition: circuit measures ~0 V regardless of switch position
Open circuit condition: signal may float or read near open-circuit voltage (varies by vehicle)

Diagnostic algorithm

Confirm code and capture live data: note voltage/logic level of 'Charge Port Door B Open Request' while operating the switch
Visually inspect switch and harness at the charge-port door for damage, corrosion, water intrusion or chafing
With ignition/key-on (per manufacturer), backprobe the switch connector. Verify voltage at the switch reference pin with switch not pressed and while pressed. Expected: HIGH (battery) when not pressed, LOW when pressed (or per vehicle logic).
If circuit is low all the time, disconnect the switch connector. If the voltage at the module side returns HIGH when switch is disconnected, suspect a shorted switch or wiring short to ground between connector and switch. If it stays LOW, suspect wiring short to ground closer to module or a module fault.
Perform continuity and resistance checks between the switch signal pin and BCM input pin. Check for short to chassis ground. Repair any shorted wiring or replace damaged connectors.
Inspect and test grounds for BCM/door controller. Clean and secure ground connections.
If wiring and switch test good, test or substitute the BCM/door controller per manufacturer procedures; verify correct module inputs and outputs.
After repair, clear codes, verify proper function of the charge port door B, and perform a drive/operation cycle to confirm code does not return.

Likely causes

Shorted wire to chassis ground between switch and BCM
Failed switch (stuck internally closed to ground)
Corroded connector pin at switch or BCM causing low reading
Water/moisture in connector causing leakage to ground

Fault status

⚠️ Status

Charge Port Door B Open Request Switch Circuit Low — signal voltage near ground when a high/pull-up voltage expected; possible short to ground, faulty switch, wiring/connector or controller issue.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.0 hours
