Check the wiring and terminals to the sensor.

I would get a subscription to alldata, it will provide a diagnostics of the circuit. I don't have one for that model so can't offer more assistance.

P0335 is Crankshaft Position Sensor Circuit code.

 

Test the wiring to the crankshaft position sensor.  Should have 5v on pin 1 between pin 1 and ground, and 5v on pin 3 between pin 3 and ground.  If you don't, gotta find where the break is.  Could be broken wire, corroded wire, bad ECM.

 

If you have already replaced the crank position sensor, you have to do a crankshaft system variation learn or this code may still be there.
