P0D59Proximity Detection Circuit A High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0D59 is logged when proximity circuit A shows a voltage above its expected resting level at a moment when the charge port must be empty. GM's Volt uses the same plausibility window as for P0D58 but trips above 4.8 V: in 2011 with the door shut or above 12.4 mph in a range other than Park, from 2016 at more than 20 km/h outside Park, over 30 of 50 or 240 of 400 samples; the fault is Type A and turns on the MIL. Mercedes defines P0D5900 for the 22 kW charger of the third-generation smart electric drive as a short to positive in the plug contact sensing, and the same bulletin blames loose charger connectors for charging and start-up problems. Electrically, a short to a supply line or a broken reference path can raise the level.
