P0D58
Proximity Detection Circuit A Low
Generic OBD-II
What it means
The proximity detection circuit A is reading lower than the module expects. The proximity circuit tells the vehicle that a charging cable is plugged in, and the car uses it to allow or block charging and driving.
Can I keep driving? Usually yes, as this mostly affects charging; get it read if charging fails. Do not open high-voltage (orange) cables or covers yourself; leave that to a trained technician.
Common symptoms
What you'll notice
- Charging does not start or stops after starting
- Charge port light or dash message shows a charging cable fault
- Vehicle may not detect the cable as plugged in
- Warning light on
Common causes
Most likely first
- Loose, corroded or damaged wiring or connector at the charge port proximity (cable-detect) line
- Dirt, moisture or damaged contacts in the charge port or on the charging cable plug
- Faulty proximity sensor or cable-detect resistor in the plug or port
- Charging cable or charging station fault giving the wrong signal
- Control module fault, or incorrect programming or calibration
How to diagnose & fix
Work through it in order
- Try a different charging cable or charging station and see whether the fault follows the cable
- Inspect the charge port and plug for dirt, moisture, bent or burnt pins and clean them gently when unplugged and the vehicle is off
- Check the wiring and connectors from the charge port to the control module for damage or corrosion
- Check the charge port proximity sensor circuit readings against the service data with a scan tool
- Only then suspect the control module and have it checked or reprogrammed by a technician
