DTC P0365 (19-21 9-Speed A/T)

DTC P0365  : Camshaft Position (CMP) Sensor Circuit No Signal

NOTE:  Before you troubleshoot, review the general troubleshooting information - Refer to: How to Troubleshoot the Fuel and Emissions Systems .

DTC (PGM-FI)

1. Problem verification

   - 1. Turn the vehicle to the ON mode.

   - 2. Clear the DTC with the HDS.

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

   - 4. Start the engine.

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

   DTC Description	Confirmed DTC	Pending DTC
   P0365 Camshaft Position (CMP) Sensor 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 the CMP sensor 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 - Refer to: How to Troubleshoot the Fuel and Emissions Systems .

2. Open wire check (IGP line)

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

   - 2. Disconnect the following connector.

   CMP sensor 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 3P connector: disconnected
   Test point 1	CMP sensor 3P connector (female terminals) No. 1:
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   The IGP wire is OK. Go to step 3.

   NO 

   Repair an open in the IGP wire between the CMP sensor and the relay circuit board.

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 3P connector: disconnected
   Test point 1	CMP sensor 3P connector (female terminals) No. 3:
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   Go to step 4.

   NO 

   Go to step 5.

4. Open wire check (TDC LG line)

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

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

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

   Is there battery voltage?

   YES 

   The TDC LG wire is OK. Replace the CMP sensor .

   NO 

   Repair an open in the TDC LG wires between the CMP sensor and G101/G202.

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 E (80P)

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

   Test condition	Vehicle OFF (LOCK) mode
   	CMP sensor 3P connector: disconnected
   	PCM connector E (80P): disconnected
   Test point 1	PCM connector E (80P) No. 77 - Refer to: PCM Connector for Inputs and Outputs (9-Speed A/T) (2019 2020 2021)
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the TDC wire between the PCM (E77) and the CMP sensor.

   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 3P connector: disconnected
   	PCM connector E (80P): disconnected
   Test point 1	CMP sensor 3P connector (female terminals) No. 3:
   Test point 2	PCM connector E (80P) No. 77 - Refer to: PCM Connector for Inputs and Outputs (9-Speed A/T) (2019 2020 2021) .

   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 - Refer to: PCM Removal and Installation (9-Speed A/T) (2019 2020 2021) , then recheck. If DTC P0365 goes away and the PCM was substituted, replace the original PCM - Refer to: PCM Removal and Installation (9-Speed A/T) (2019 2020 2021) .

   NO 

   Repair an open in the TDC wire between the PCM (E77) and the CMP sensor.
