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

   -4. Enter the maintenance mode, then start the engine, and let it idle .

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

   DTC Description	Confirmed DTC	Pending DTC
   P0335 CKP Sensor No Signal

   DTC (PGM-FI)

   Is DTC P0335 indicated?

   YES 

   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. Determine possible failure area (VCC1/VCC line, others)

   -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. 3:
   Test point 2	Body ground

   Is there about 5.0 V?

   YES 

   Go to step 4.

   NO 

   Go to step 3.

3. Open wire check (VCC1/VCC 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	CKP sensor 3P connector (female terminals) No. 3:
   Test point 2	PCM connector E (80P) No. 70

   Is there continuity?

   YES 

   The VCC1/VCC 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 VCC1/VCC wire between the PCM (E70) and the CKP sensor.

4. Determine possible failure area (CRKP 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. 1:
   Test point 2	Body ground

   Is there about 5.0 V?

   YES 

   Go to step 5.

   NO 

   Go to step 7.

5. Determine possible failure area (SG1/SG 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. 2:
   Test point 2	CKP sensor 3P connector (female terminals) No. 3:

   Is there about 5.0 V?

   YES 

   The SG1/SG wire is OK. Replace the CKP sensor .

   NO 

   Go to step 6.

6. Open wire check (SG1/SG 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	CKP sensor 3P connector (female terminals) No. 2:
   Test point 2	PCM connector E (80P) No. 71

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

   Is there continuity?

   YES 

   The SG1/SG 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 SG1/SG wire between the PCM (E71) and the CKP sensor.

7. Shorted wire check (CRKP 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. 44
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the CRKP wire between the PCM (E44) and the CKP sensor.

   NO 

   The CRKP wire is not shorted. Go to step 8.

8. Open wire check (CRKP line)

   -1. 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	CKP sensor 3P connector (female terminals) No. 1:
   Test point 2	PCM connector E (80P) No. 44
