DTC P0365 (2.4 L Engine) (2017 2018 2019)

DTC P0365  : CMP Sensor B Circuit No Signal

NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Start the engine.

   -4. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC
   P0365 CMP Sensor B Circuit No Signal

   Is DTC P0365 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 CMP sensor B and the PCM. 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. Open wire check (IGP (TDC)/IGP (MAIN)/FI MAIN RLY OUT line)

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

   -2. Disconnect the following connector.

   CMP sensor B 3P connector

   -3. Turn the vehicle to the ON mode.

   -4. Measure the voltage between test points 1 and 2.

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

   Is there battery voltage?

   YES 

   The IGP (TDC)/IGP (MAIN)/FI MAIN RLY OUT wire is OK. Go to step 3.

   NO 

   Repair an open in the IGP (TDC)/IGP (MAIN)/FI MAIN RLY OUT wire between CMP sensor B and the relay circuit board (PGM-FI main relay 1 circuit).

3. Determine possible failure area (TDC line, others)

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

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

   Is there about 5.0 V?

   YES 

   Go to step 4.

   NO 

   Go to step 5.

4. Open wire check (LG/LG2 line)

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

   Test condition	Vehicle ON mode
   	CMP sensor B 3P connector: disconnected
   Test point 1	CMP sensor B 3P connector (female terminals) No. 1:
   Test point 2	CMP sensor B 3P connector (female terminals) No. 2:

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

   Is there battery voltage?

   YES 

   The LG/LG2 wire is OK. Replace CMP sensor B .

   NO 

   Repair an open in the LG/LG2 wire between CMP sensor B and G101.

5. Shorted wire check (TDC line)

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

   -2. Jump the SCS line with the HDS, and wait more than 1 minute.

   -3. Disconnect the following connector.

   PCM connector B (51P)

   -4. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	CMP sensor B 3P connector: disconnected
   	PCM connector B (51P): disconnected
   Test point 1	PCM connector B (51P) No. 30

   Test point 2

   Body ground

   Is there continuity?

   YES 

   Repair a short in the TDC wire between the PCM (B30) and CMP sensor B.

   NO 

   The TDC wire is not shorted. Go to step 6.

6. Open wire check (TDC line)

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

   Test condition	Vehicle OFF (LOCK) mode
   	CMP sensor B 3P connector: disconnected
   	PCM connector B (51P): disconnected
   Test point 1	CMP sensor B 3P connector (female terminals) No. 3:
   Test point 2	PCM connector B (51P) No. 30

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

   Is there continuity?

   YES 

   The TDC wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good PCM .

   NO 

   Repair an open in the TDC wire between the PCM (B30) and CMP sensor B.
