2004 Nissan Sentra 1.8S that stopped running, it threw code P0335 (Crankshaft Position Sensor) which I replaced; the CEL will not go out, and I was wondering if the CEL must be cleared using a handheld device or should the battery negative being off for 30 minutes have cleared it? I am worried about driving long distance with the light on even though I just replaced the sensor. I did have the code read again after the sensor was replaced and it showed a P0335 again. Thank you - John

One possibility is the Crankshaft Position Sensor. If this is bad, you will not get spark. You would have a CEL illuminated, though. ( code P0335)

"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."



did you clear the trouble code first and see if it returned?!?

P0335

code p0335 refers to crankshaft position sensor ( CKP)-circuit malfunction === causes --wiring---CKP sensor---ECM Replace the sensor.

need to replace the camshaft sensor also in tandem w/crankshaft sensor. trouble codes need to be removed from computer. after repair. both the air & fuel filters need replaced. how's your oil change doin ? try this brandi, see if that takes care of it .

it is On the back side of the block(below the intake manifold). on 1.8 engine. nissan sentra.

Diagnostic Trouble Code (DTC) P0335

Magnetic Crankshaft Position Sensor Electrical Error

In this circuit DTC (data trouble code) sets when

a) The magnetic crankshaft position sensor is > 0.2V.

Or when

b) The minimum value of magnetic crankshaft position sensor is

Or when

c) The maximum value of magnetic crankshaft position sensor is higher than 2.2V.

Note - not a solution..just adding my woes!
I drive a 2003 Nissan Sentra SE-R Spec V.
My car suddenly stalled 1 day and the engine wouldn\'t turn over. Brought it to my mechanic and had the Camshaft position sensor replaced by my mechanic. The car ran fine for about 2 weeks and then the light was back on with the initial symptoms.

Took the car into the dealership and they diagnosed it again as P0335. Said that the mechanic hadn\'t installed the sensor correctly. Charged me a bunch of money to replace the thing and not too long ago the check engine light is on. The Revs bounce around everywhere. Checked the code again and it\'s P0335 yet again! Am in talks with the dealership to get to the bottom of this...

In the kit there are two sensor that look identical. The one for the crankshaft has a white paint mark on it near the bolt hole. Make sure that it is in the right location.

crank sensors are usually located in/near the distributor.

check the fuel pump first.after that check the fuel filter. probably it is clogged.these parts are loacted in your fuel tank floater.remove the back seat.remove the screws.your car is young so the crankshaft position sensor must be working properly.
