DTC P0335 CKP SENSOR (POS)
The crankshaft position sensor (POS) is located on the cylinder block rear housing facing the gear teeth (cogs) of the signal plate at the end of the crankshaft. It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet and hall IC. When the engine is running the high and low parts of the teeth cause the gap with the sensor change.
The changing gap causes the magnetic field near the sensor to change.
Due to the changing magnetic field the voltage from the sensor changes.
The ECM receives the voltage signal and detects the fluctuation of the engine revolution.

DTC Confirmation Procedure
NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.
Before performing the following procedure, confirm that battery voltage is more than 10.5 V with ignition switch "ON".
Turn ignition switch "ON" and select "DATA MONITOR" mode with CONSULT-II.
Crank engine for at least 2 seconds and run it for at least 5 seconds at idle speed.
If 1st trip DTC is detected, go to "Diagnostic Procedure". If 1st trip DTC is not detected, go to next step.
Maintaining engine speed at more than 800 rpm for at least 5 seconds.
If 1st trip DTC is detected, go to "Diagnostic Procedure".
Follow the procedure "WITH CONSULT-II" above.
Diagnostic Procedure Step 1
Diagnostic Procedure Step 2 - 4
Diagnostic Procedure Step 5 - 8
CRANKSHAFT POSITION SENSOR (POS)
Loosen the fixing bolt of the sensor.
Disconnect crankshaft position sensor (POS) harness connector.
Remove the sensor.
Visually check the sensor for chipping.
Check resistances shown in the figure.
It more involved than replacing the sensor.
