DTC Advanced Diagnostics: P16E3 (1.5L Engine)

DTC P16E3:  PGM-FI-Battery Sensor LIN Communication Error

General Description 

Courtesy of HONDA, U.S.A., INC.

The local interconnect network (LIN) line connects the 12 volt 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 12 volt battery sensor unit is the slave. The 12 volt 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 12 volt battery sensor within its specified amount of time, the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter

Malfunction Threshold 

Either one of the conditions is met for at least 5 seconds:

• The PCM cannot receive any information from the 12 volt battery sensor via the LIN line.
• The information sent from the 12 volt battery sensor is abnormal.

Possible Cause 

Diagnosis Details 

Conditions for setting the DTC 

When a malfunction is detected, a Pending DTC, a Confirmed DTC, the freeze data, and the on-board snapshot are stored in the PCM memory. The MIL does not come on.

Conditions for clearing the DTC 

The Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
