DTC Advanced Diagnostics: P16E3 (3.0L 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 alternator 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 slave node communicates according to the master node. If the PCM cannot receive signals from the 12 volt battery sensor or the received information is abnormal, the PCM detects a malfunction and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type

Execution	Continuous
Sequence	None
Duration	20 seconds or more
DTC Type	Two drive cycles, MIL off

Enable Conditions

Condition	Minimum	Maximum
PCM voltage	9.5 V	-
Vehicle	ON mode
Other	CAN communication between PCM and gauge control module is OK

Malfunction Threshold

Either one of the conditions is met for at least 20 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

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

12 volt battery sensor LIN(METER) line short
12 volt battery sensor LIN(METER) line open
12 volt battery sensor power supply line open
12 volt battery sensor failure
Gauge control module internal circuit failure (LIN communication circuit)

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, a Confirmed DTC, the freeze data, and the on-board snapshot are stored. 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.
