DTC P0365

DTC P0365  : CMP Sensor Circuit No Signal

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	Freeze Frame
   P0365 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 freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

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 circuit	IGP
   Test point 1	CMP sensor 3P connector No. 1 (YEL)
   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 PGM-FI main relay 1.

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 circuit	TDC
   Test point 1	CMP sensor 3P connector No. 3 (GRY)
   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 line)

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

   Test condition	Vehicle ON mode
   	CMP sensor 3P connector: disconnected
   Test circuit	IGP, LG
   Test point 1	CMP sensor 3P connector No. 1 (YEL)
   Test point 2	CMP sensor 3P connector No. 2 (BRN)

   Is there battery voltage?

   YES 

   The LG wire is OK. Replace the CMP sensor .

   NO 

   Repair an open in the LG wire between the CMP sensor 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.

   - 3. Disconnect the following connector.

   PCM connector B (51P) - Refer to: How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016), or How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the A/T System (2014 2015)

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

   Test condition	Vehicle OFF (LOCK) mode
   	CMP sensor 3P connector: disconnected
   	PCM connector B (51P): disconnected
   Test circuit	TDC
   Test point 1	PCM connector B (51P) No. 51 (GRY)
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the TDC wire between the PCM (B51) 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 B (51P): disconnected
   Test circuit	TDC
   Test point 1	CMP sensor 3P connector No. 3 (GRY)
   Test point 2	PCM connector B (51P) No. 51 (GRY)

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

   Is there continuity?

   YES 

   The TDC wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM - Refer to: PCM Removal and Installation (2014 2015), or PCM Removal and Installation (2016) .

   NO 

   Repair an open in the TDC wire between the PCM (B51) and the CMP sensor.
