P2E87Proximity Detection Circuit B
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E87 is the general fault of a second plug-detection circuit, B, whose job is to tell the vehicle that a connector is seated in an inlet. Under SAE J1772 this proximity pin is tied to earth through resistors and a switch in the latch button, so the car can lock out driving and wind down current before the plug comes out; CHAdeMO inlets have their own proximity contact for the same interlock. A second circuit is needed where a car carries two inlets, as the Outlander PHEV does with its normal and quick-charge sockets: Mitsubishi reports the normal one as proximity A (P0D58/P0D59) and reads a separate quick-charger connecting voltage, without publishing a B code. No manufacturer documents P2E87. Lear patented a circuit that also wakes the charger through this line. Expect no charging on that inlet.
- What you may notice
- No charging through the affected inlet
- Plug not recognised or vehicle reports a cable while none is fitted
- Vehicle may refuse to enter drive readiness
- Likely causes
- LikelyDamaged or corroded proximity contact in inlet B
- PossibleOpen or poorly seated connector between inlet B and the controller
- PossibleFaulty charging cable or plug resistor
- RareEvaluation circuit in the charger or control unit faulty
