P0D58Proximity Detection Circuit A Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0D58 reports a voltage on proximity circuit A that is too low while no plug can possibly be inserted. GM's Volt checks this in its hybrid control processor: in 2011 with the charge door closed or above 12.4 mph in a range other than Park, from 2016 above 20 km/h outside Park, the signal must sit in a window, and less than 4.2 V for 30 of 50 samples (later 240 of 400) sets the code as a Type A fault with immediate MIL. In the third-generation smart electric drive with 22 kW charger, Mercedes defines P0D5800 as a short to ground of this contact sensing; bulletin LI54.10-P-067823 links it to loose low-voltage plugs at the charger, a car that will not start and a cable-plugged-in message. The high counterpart is P0D59.
