P2E88Proximity Detection Circuit B Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E88 flags plug sensing on circuit B whose value is electrically valid but makes no sense, typically a voltage that falls between the defined steps for no plug, plug latched and release button pressed. Those steps come from fixed resistors: J1772 uses 150 Ω plus 330 Ω once the latch is opened, and IEC 62196 cables code their current rating with values from about 100 Ω to 1.5 kΩ, each read within a tolerance band. Supplier controllers such as Watt & Well's EVCC bias the pin with 5 V and treat less than 3.5 kΩ as a plug, more than 4 kΩ as none. No manufacturer documents P2E88; for circuit A FCA cured P0D57 on the 2017 Pacifica plug-in hybrid by reflashing its hybrid control processors. Worn contacts or an off-standard cable are common. Hard faults are P2E89 and P2E8A.
- What you may notice
- Charging aborts or the current is limited unexpectedly
- Plug status changes without anyone touching the connector
- Fault appears only with certain cables
- Likely causes
- LikelyWorn or dirty proximity contact raising the resistance
- PossibleCharging cable or adapter with off-standard coding resistor
- PossibleMoisture in inlet B creating leakage paths
- RareControl software judging the signal wrongly
- Repair
- Medium · Usually a job for a workshop.Typical cost: €0 – €900
