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	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 (CRK)/IGP (MAIN)/FI MAIN RLY OUT 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 No. 3
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   The IGP (CRK)/IGP (MAIN)/FI MAIN RLY OUT wire is OK. Go to step 3.

   NO 

   Repair an open in the IGP (CRK)/IGP (MAIN)/FI MAIN RLY OUT wire between the CKP sensor and PGM-FI main relay 1.

3. Determine possible failure area (CRANK line, LG 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 No. 1
   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
   	CKP sensor 3P connector: disconnected
   Test point 1	CKP sensor 3P connector No. 2
   Test point 2	CKP sensor 3P connector No. 3

   Is there battery voltage?

   YES 

   The LG wire is OK. Replace the CKP sensor .

   NO 

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

5. Shorted wire check (CRANK 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)

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

   Test condition

   Vehicle OFF (LOCK) mode

   	CKP sensor 3P connector: disconnected
   	PCM connector B (51P): disconnected
   Test point 1	PCM connector B (51P) No. 11
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short in the CRANK wire between the PCM (B11) and the CKP sensor.

   NO 

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

6. Open wire check (CRANK line)

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

   Terminal A	CKP sensor 3P connector No. 1
   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. 1: jumped to body ground
   	PCM connector B (51P): disconnected
   Test point 1	PCM connector B (51P) No. 11
   Test point 2	Body ground

   Is there continuity?

   YES 

   The CRANK wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM , then recheck. If DTC P0335 goes away and the PCM was updated, troubleshooting is complete. If DTC P0335 goes away and the PCM was substituted, replace the original PCM .

   NO 

   Repair an open in the CRANK wire between the PCM (B11) and the CKP sensor.
