P2D37 code meaning
Hybrid/EV Battery Inductive Charger Input Circuit Range/Performance
What P2D37 means
P2D37 looks at the input of the inductive charger, the high-frequency AC that arrives from the vehicle pickup coil before rectification. The measured input is present but implausible: it fits neither the power being transferred nor the other readings, or it does not react when the transfer ramps up. Clear low and high readings have their own codes, P2EB5 and P2EB6. No manufacturer documents P2D37 publicly. The input depends on coupling across the air gap: the Magne Charge paddle worked at 130 to 360 kHz, current J2954 systems at 85 kHz, and coil offset or a foreign object changes what reaches the vehicle. Hyundai patent US10245962B2 has the vehicle controller read the secondary-coil voltage or current for exactly this regulation. Check pad alignment and coil connectors before replacing modules.
P2D37 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2D37
- Inductive charging starts with low power or not at all
- Positioning aid reports the car as aligned, but charging still fails
Common causes of P2D37
- Most likelyDamaged or loose connection between pickup coil and charger module
- PossibleLarge coil offset, excessive ground clearance or metal object on the pad
- PossibleFaulty input voltage or current sensing inside the charger module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2D37 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 37 | The exact fault in that area. |
What to do next
- Note P2D37 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2D37
What does P2D37 mean?
P2D37 means "Hybrid/EV Battery Inductive Charger Input Circuit Range/Performance". P2D37 looks at the input of the inductive charger, the high-frequency AC that arrives from the vehicle pickup coil before rectification. It is a generic code, so it means the same on every make.
Is it safe to drive with P2D37?
P2D37 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2D37 fail an emissions test?
P2D37 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2D37 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2D37 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
