DTC Advanced Diagnostics: P058A (2025)
DTC P058A : Battery Sensor Internal Failure
General Description
The 12 volt battery sensor is connected between the 12 volt battery and ground. The 12 volt battery sensor measures the 12 volt battery's current, voltage, and temperature. The measured value is sent to the powertrain control module (PCM) via the local interconnect network (LIN) line by the request of the PCM. The 12 volt battery sensor has a self-diagnostic function and sends the results to the PCM via the LIN line. If the self-diagnostic result is abnormal, the PCM detects a malfunction and stores a DTC.

- 12 volt battery sensor internal failure
Diagnosis Details* 1
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, the freeze data, and the on-board snapshot are stored in the PCM memory.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
