P0D41: Battery Charger A Input Voltage Sensor A Circuit Intermittent/Erratic

P0D41 is reserved for an input voltage sensor A signal at charger A that is intermittent or erratic, i.e. it jumps or drops out briefly. No manufacturer documents this code with set conditions; GM and Mitsubishi only use P0D3E-P0D40 for this sensor. GM's information bulletin 12-08-45-001A shows how unstable household supplies appear in practice: electrical noise on the AC line can disturb charging on the Volt, ELR and Spark EV, sometimes together with P0D3F or P0D3E. CARB's rules for input components cover such signal faults in general. Possible causes are poor contacts between inlet and charger, a degrading sensor in the charger, or a noisy supply. Charging may stop and restart unpredictably; driving continues.

Symptoms

• Charging stops and restarts unpredictably
• Fault appears only at one charging location

Most likely causes

• Electrical noise or poor grounding on the AC supply
• Loose contact between charge inlet and charger
• Voltage measurement in the charger degrading

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. Gently move the wiring with the engine running and watch whether the reading changes.
3. Make sure the battery cooling air intake is clean
4. Check the 12 V auxiliary battery, which can also trigger warnings
5. Leave any high-voltage measurements to a specialized repair shop

Good to know

• Repair difficulty: medium

What each character of P0D41 means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• D: Subsystem depends on the code range
• 41: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0D41?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0D41?

The most common causes are: electrical noise or poor grounding on the AC supply; loose contact between charge inlet and charger; voltage measurement in the charger degrading.
