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 (IGP(CRANK)/IGP(MAIN)/FI MAIN RLY OUT line):

Test point 2
CKP sensor 3P connector (female terminals) No. 3:


Is there battery voltage?

     
YES
     
     
     
The LG/LG2 wire is OK. Replace the CKP sensor.?
     
NO
     
     
     
Repair an open in the LG/LG2 wire between the CKP sensor and G101.?
5.
Shorted wire check (CRKN line):

Shorted wire check (CRKN 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 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. 38
Test point 2
Body ground

Is there continuity?

     
YES
     
     
     
Repair a short in the CRKN wire between the PCM (B38) and the CKP sensor.?
     
NO
     
     
     
The CRKN wire is not shorted. Go to step 6.
6.
Open wire check (CRKN line):

Open wire check (CRKN line)
?1.
Connect terminals A and B with a jumper wire.
Terminal A
CKP sensor 3P connector (female terminals) No. 1:
Terminal B
