DTC P16E3: PGM-FI-Battery Sensor LIN Communication Error (2013-17)
General Description
2013 - 2015 models:
2016 model on and after:
The local interconnect network (LIN) line connects the battery sensor and the powertrain control module (PCM). The LIN uses a master/slave protocol to send and receive data to the different components on the line.The PCM is the master unit, which controls the engine electrical system. The battery sensor and the alternator are the slaves. The battery sensor receives data from the PCM and provides feedback to the PCM, which allows the PCM to operate the engine electrical system efficiently. When the PCM does not receive signals from the battery sensor within its specified amount of time, the PCM detects a malfunction and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type, OBD Status
| Execution | Continuous |
| Sequence | None |
| Duration | 5 seconds or more |
| DTC Type | One drive cycle, MIL off |
| OBD Status | PASSED/FAILED/NOT COMPLETED (STILL TESTING) |
Enable Conditions
| Condition | Minimum | Maximum |
|---|---|---|
| Elapsed time after the engine start/stop button is pressed to select the ON mode | 3 seconds | - |
| Battery voltage [BATTERY] | 10.0 V | - |
[ ]: HDS Parameter
Malfunction Threshold
Either one of the conditions is met for at least 5 seconds:
- The PCM cannot receive any information via the LIN line.
- The information sent from the battery sensor is abnormal.
Possible Cause
- Battery sensor failure (include fuse blown)
- Battery sensor LIN line open
- Battery sensor LIN line short
- PCM internal circuit failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.
Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
