P2E89Proximity Detection Circuit B Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E89 stands for a voltage on proximity circuit B below the band the controller accepts in a state where no plug can be present. The rule for circuit A shows how this is judged: GM's Volt checks the line with the charge door closed or while driving out of Park and sets P0D58 below 4.2 V, in 2011 after 30 failures out of 50, in the 2019 tables after 240 out of 400 samples above 20 km/h, as a Type A code with MIL. Mitsubishi's 2023 Outlander PHEV sets P0D58-00 on a low input of the charger connection signal and checks the line to the PHEV-ECU for a ground short, the charging cable and even outside supply equipment. No manufacturer documents P2E89 itself. A Lear patent protects the 5 V feed of such circuits against shorts. Expect a car that believes a plug is in.
