P2E8AProximity Detection Circuit B High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E8A is the opposite of P2E89: the proximity line of circuit B sits above the accepted band. Because the evaluating controller usually pulls the pin up to a reference such as 5 V, as described for Watt & Well's EVCC, an open wire or a missing earth path reads high just like a short to a supply. For circuit A GM's Volt sets P0D59 above 4.8 V under the same conditions as the low test, charge door closed or moving out of Park, again Type A with MIL. Mitsubishi's 2023 Outlander PHEV logs P0D59-00 on a high charger connection signal and points to the harness between charger and PHEV-ECU or the PHEV-ECU itself. No manufacturer documents P2E8A. The usual result is a plug on inlet B that is never recognised, so charging there does not start.
