P0D53: Battery Charger Hybrid/EV Battery Output Current Sensor Circuit Low

P0D53 is set when the charger's output current sensor reports a value below its valid floor. GM's charger module in the 2011 and 2014 Volt and the ELR uses a decoded current of 0.098 A or less, present for 400 of 500 ms with the low- and high-voltage sections awake; the fault is Type A, so the MIL lights after one trip, and the power checks P0D5C and P1ECE stay disabled while it is active. Mitsubishi defines it for the 2022 Outlander PHEV as a ground short once the sensor output falls under 2.349 V, equivalent to about -3.8 A, for 0.5 s; charging stops and the charger/DC-DC unit is to be replaced. The high counterpart is P0D54; offset errors are P0D52.

High severity. Can I keep driving?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.

Symptoms

Charging stops or never begins
MIL on (GM)
Charging fault indicated at the charge port or in the cluster

Most likely causes

Current sensor output shorted to ground inside the charger
On-board charger measuring electronics failed
Supply of the current sensor missing

What to check, in order

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

Read the codes with a hybrid-compatible scanner and write down the freeze frame data
With the connector unplugged, check whether the signal wire is making contact with ground.
Make sure the battery cooling air intake is clean
Check the 12 V auxiliary battery, which can also trigger warnings
Leave any high-voltage measurements to a specialized repair shop

What each character of P0D53 means

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

Frequently asked questions

Can I keep driving with code P0D53?

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 P0D53?

The most common causes are: current sensor output shorted to ground inside the charger; on-board charger measuring electronics failed; supply of the current sensor missing.
