DTC P0335

DTC P0335  : CKP Sensor 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
   P0335 CKP Sensor No Signal

   Is DTC P0335 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 CKP 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.

   CKP 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
   	CKP sensor 3P connector: disconnected
   Test circuit	IGP
   Test point 1	CKP 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 CKP sensor and PGM-FI main relay 1.

3. Determine possible failure area (CRK line, CRK LG/LG line)

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

   Test condition	Vehicle ON mode
   	CKP sensor 3P connector: disconnected
   Test circuit	CRK
   Test point 1	CKP sensor 3P connector No. 3 (BLU)
   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 (CRK LG/LG line)

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

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

   Is there battery voltage?

   YES 

   The CRK LG/LG wire is OK. Replace the CKP sensor .

   NO 

   Repair an open in the CRK LG/LG wire between the CKP sensor and G101.

5. Shorted wire check (CRK 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 C (51P) - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the A/T System (2014 2015), or 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)

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

   Test condition	Vehicle OFF (LOCK) mode
   	CKP sensor 3P connector: disconnected
   	PCM connector C (51P): disconnected
   Test circuit	CRK
   Test point 1	PCM connector C (51P) No. 11 (BLU)
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the CRK wire between the PCM (C11) and the CKP sensor.

   NO 

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

6. Open wire check (CRK line)

   -1. Connect terminals A and B with a jumper wire.

   Terminal A	CKP sensor 3P connector No. 3 (BLU)
   Terminal B	Body ground

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

   Test condition	Vehicle OFF (LOCK) mode
   	CKP sensor 3P connector: disconnected
   	CKP sensor 3P connector No. 3: jumped to body ground
   	PCM connector C (51P): disconnected
   Test circuit	CRK
   Test point 1	PCM connector C (51P) No. 11 (BLU)
   Test point 2	Body ground

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

   Is there continuity?

   YES 

   The CRK 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 CRK wire between the PCM (C11) and the CKP sensor.
