DTC P16E3 (1.5 L Engine)

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

NOTE: 

• Before you troubleshoot, review the general troubleshooting information .
• Check for loose terminals on the 12 volt battery sensor (12 volt battery negative (-) terminal).

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS, and wait for 60 seconds.

   -3. Check for Pending or Confirmed DTCs with the HDS.

   P16E3 PGM-FI-Battery Sensor LIN Communication Error

   Is DTC P16E3 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the 12 volt battery sensor and the gauge control module. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

2. 12 volt battery sensor power supply check

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connector.

   12 volt battery sensor 3P connector

   -3. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	12 volt battery sensor 3P connector: disconnected
   Test point 1	12 volt battery sensor 3P connector (female terminals) No. 2:
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   Go to step 4.

   NO 

   Go to step 3.

3. Fuse check

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Check the following fuse.

   Fuse

   No. A28

   Is the fuse OK?

   YES 

   Repair an open in the +B HORN wire between the 12 volt battery sensor and the No. A28 fuse.

   NO 

   Repair a short in the +B HORN wire between the 12 volt battery sensor and the No. A28 fuse. Also replace the No. A28 fuse.

4. Determine possible failure area (12 volt battery sensor, others)

   -1. Turn the vehicle to the ON mode.

   -2. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode
   	12 volt battery sensor 3P connector: disconnected
   Test point 1	12 volt battery sensor 3P connector (female terminals) No. 3:
   Test point 2	Body ground

   Is there 0 V?

   YES 

   Go to step 5.

   NO 

   Replace the 12 volt battery sensor .

5. Determine possible failure area (LIN (BATT SNSR) line shorted, others)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	12 volt battery sensor 3P connector: disconnected
   Test point 1	12 volt battery sensor 3P connector (female terminals) No. 3:
   Test point 2	Body ground

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

   Is there continuity?

   YES 

   Go to step 6.

   NO 

   The LIN (BATT SNSR) wire is not shorted. Go to step 7.

6. Shorted wire check (LIN (BATT SNSR) line)

   -1. Disconnect the following connector.

   Gauge control module connector A (32P)

   -2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Gauge control module connector A (32P): disconnected
   	12 volt battery sensor 3P connector: disconnected
   Test point 1	12 volt battery sensor 3P connector (female terminals) No. 3:
   Test point 2	Body ground

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

   Is there continuity?

   YES 

   Repair a short in the LIN (BATT SNSR) wire between the 12 volt battery sensor and the gauge control module.

   NO 

   The LIN (BATT SNSR) wire is OK. Replace the gauge control module .

7. Open wire check (LIN (BATT SNSR) line)

   -1. Disconnect the following connector.

   Gauge control module connector A (32P)

   -2. Connect terminals A and B with a jumper wire.

   Terminal A	Gauge control module connector A (32P) No. 4
   Terminal B	Body ground

   -3. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	12 volt battery sensor 3P connector: disconnected
   	Gauge control module connector A (32P): disconnected
   	Gauge control module connector A (32P) No. 4: jumped to body ground
   Test point 1	12 volt battery sensor 3P connector (female terminals) No. 3:
   Test point 2	Body ground

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

   Is there continuity?

   YES 

   The LIN (BATT SNSR) wire is OK. Replace the gauge control module .

   NO 

   Repair an open in the LIN (BATT SNSR) wire between the 12 volt battery sensor and the gauge control module.
