P0335 2004 Nissan Sentra -

Question

This is what I've read on my Can OBD2 code reader: P0335, fuel system 1 - CL, fuel system 2 - CL-fault, Calc Load (%) - 17.25, ECT(F) - 172, STFT B1(%) - 25.00, LIFT B1(%) - minus 9.38, ENG RPM - 2625, VEH Speed - 67. I have replaced the in tank fuel pump because of frequent hard starts and drove car around town for the weekend. Engine ran well. On the way to work this morning, same as last week when coming home, engine stalled at highway speed after about ten minutes driving. I moved over to the side of the road and noticed service engine soon light come on and stayed on. The car cranked up after about ten minutes and would drive for about five minutes then stall again. I finally got home after repeating this process three times. Does the fuel system 2 - CL-fault mean anything? If not, what would be the next step? crank sensor?

Answer 1

check your battery and charging system first if its good, replace the crackshaft position sensor

 

Possible causes

- Faulty crankshaft position sensor

- Crankshaft position sensor harness is open or shorted

- Crankshaft position sensor circuit poor electrical connection

- Signal plate may be damage

- Starter motor may be faulty

- Starting system circuit

- Dead or weak battery
