P2D36 code meaning
Hybrid/EV Battery Inductive Charger Output Voltage Performance
What P2D36 means
P2D36 judges the DC side of the inductive charger: the voltage it hands to the traction battery is outside what the controller expects for the current state, too low to push charge current or above what the battery may accept. No manufacturer documents P2D36 publicly. How the vehicle side regulates this output is shown in Hyundai patent US10245962B2: the vehicle assembly rectifies the coil power with a bridge whose two switching legs change timing to raise or lower output, can shift its pad to alter coupling, and fine-tunes until the measured secondary current matches the target; the example runs at about 400 V. SAE J2954 sets the wireless power classes this must cover. Causes include a failing rectifier or filter, a drifting voltage sensor or a badly aligned car. P2D37 covers the input side. Charging is usually stopped.
P2D36 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 P2D36
- Inductive charging stops shortly after it begins
- Charging power far below the expected value
Common causes of P2D36
- Most likelyFaulty rectifier, switching stage or output filter in the vehicle assembly
- PossibleOutput voltage sensor drifting against the battery voltage measurement
- PossibleVehicle parked off-centre over the ground pad, so the output cannot be held
- Less likelyRegulation software of 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 P2D36 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 36 | The exact fault in that area. |
What to do next
- Note P2D36 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 P2D36
What does P2D36 mean?
P2D36 means "Hybrid/EV Battery Inductive Charger Output Voltage Performance". P2D36 judges the DC side of the inductive charger: the voltage it hands to the traction battery is outside what the controller expects for the current state, too low to push charge current or above what the battery may accept. It is a generic code, so it means the same on every make.
Is it safe to drive with P2D36?
P2D36 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2D36 fail an emissions test?
P2D36 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 P2D36 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2D36 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
