P0D80: Battery Charger Input Circuit/Open

P0D80 means the on-board charger sees no usable AC supply at its input even though the charging handshake says power should be there. Ford documents the check for its plug-in hybrids in the OBD summaries for model years 2014 to 2018: with the cable connected, the EVSE active and the S2 switch closed, an input below 85 VAC lasting 30 seconds sets the code, and Ford's code dictionary marks it as a MIL code. The fault can therefore lie outside the car, for example a dead EVSE or a tripped breaker, as well as in the charge inlet, the AC harness or the charger itself. P0D81 to P0D84 cover implausible or electrically wrong input signals, P0D27 a supply that is present but too low. The driver notices that the car does not charge.

Symptoms

• Vehicle does not charge although the cable is plugged in
• Charging fault message or flashing fault pattern at the charge port
• Check engine light

Most likely causes

• Charging station or outlet delivers no AC after the handshake (fault, tripped breaker)
• Open AC contact or wire between charge inlet and charger
• Fault in the charger's input stage or voltage measurement

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. Check the continuity of the wire between the component and the control module.
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 P0D80 means

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

Frequently asked questions

Can I keep driving with code P0D80?

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 P0D80?

The most common causes are: charging station or outlet delivers no AC after the handshake (fault, tripped breaker); open AC contact or wire between charge inlet and charger; fault in the charger's input stage or voltage measurement.
