DTC P0335

DTC P0335  : CKP Sensor 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
   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 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 (IGP1/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 point 1	CKP sensor 3P connector (female terminals) No. 1:
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   The IGP1/IGP wire is OK. Go to step 3.

   NO 

   Repair an open in the IGP1/IGP wire between the CKP sensor and PGM-FI main relay 1.

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

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

   Test condition	Vehicle ON mode
   	CKP sensor 3P connector: disconnected
   Test point 1	CKP sensor 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 (CRK LG/PHC GND line)

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

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

   Is there battery voltage?

   YES 

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

   NO 

   Repair an open in the CRK LG/PHC GND 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, 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
   	CKP sensor 3P connector: disconnected
   	PCM connector E (80P): disconnected
   Test point 1	PCM connector E (80P) No. 61
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the CRK wire between the PCM (E61) 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 (female terminals) No. 3:
   Terminal B	Body ground

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

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

   Test condition	Vehicle OFF (LOCK) mode
   	CKP sensor 3P connector: disconnected
   	PCM connector E (80P): disconnected
   	CKP sensor 3P connector No. 3: jumped to body ground
   Test point 1	PCM connector E (80P) No. 61
   Test point 2	Body ground

   Is there continuity?

   YES 

   The CRK wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM , then recheck. If DTC P0335 goes away and the PCM was substituted, replace the original PCM .

   NO 

   Repair an open in the CRK wire between the PCM (E61) and the CKP sensor.
