P0335 code

Component Description

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 to 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.

On Board Diagnosis Logic




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.

TESTING CONDITION: Before performing the following procedure, confirm that the battery voltage is more than 10.5V and the ignition switch is "ON".

WITH CONSULT-II






1.Turn ignition switch "ON" and select "DATA MONITOR" mode with CONSULT-II.
2.Crank engine for at least 2 seconds and run it for at least 5 seconds at idle speed.
3.If 1st trip DTC is detected, go to "Diagnostic Procedure" below.


codes never identify bad parts, just failed systems.

Did you use a factory sensor?

Roy

I took the car into Nissan and had them put the factory sensor in. They told me it was not responding and that it was probably the ECU. I bought a new ECU and it didn't fix the problem.
I had a reputable mechanic install the ECU for me after they checked wire continuity. I'm not sure what computer they used to program the ECU. I assume it was a consult II. If the sensor is good and the ECU is good then what else would cause the problem?

Okay, assuming all the wiring is good, it could be the wheel that the crank sensor is running around or the gap itself.

Hard to say being as i am here and not there. i always like to look at things myself and i don't take the word of anyone working on it as I am the one now responsible for fixing it.

Roy

How would I check the wheel and where is it located? How do I check the gap? The engine rust like its out of time or retarded slightly.

it is behind the crank gear. the front of the motor would have to be disassembled to access.

Roy

The engine runs like it's out of time ( sorry).

Could it be that the timing chain has stretched? Have you ever heard of that happening?

Yes, i have and with 180,000 it very well could be part of the issue. replacing it will be expensive but if it is in good condition, it would be worth it in the long run.

Roy

I will check to see if the timing marks are lining up.

I took valve cover off and rotated the crank to TDC. I checked where timing marks are and they looked okay. Through some new pugs in while I was at it. Put it back together and went to start it. It started briefly and then shut off. Now it wont start. All I did is rotate the motor to TDC. What do you think happened?

did you do a compression test???

Roy

Yes. All cylinders seem low but how could I have don that? All I did was rotate the crank to TDC to see where the timing marks were on the cams. Feeling sick right about now.

Do you have any idea what possibly could have happened?

All cylinders are between 120 - 125 PSI.

That's not bad. sounds like you have your timing right.

check spark at the plugs cranking.

Roy

Trouble code P0335: Does this code make the engine stall and after eng cool down, it restarts and can be driven until stops again?
Where is the crankshaft position sensor located? Engine is 1.8L automatic trans.

Yes, the P0355 can cause engine to stall or not to start at all.
Intermittent problems cna be due to loose or contaminated wireharness connectors.

Sensor is on right rear side of engine block.

I have a 2004 sentra (basic) I just replaced the cad and crankshaft
First is on the right of the engine block exposed and easy to replace
the second is behind the starter (a real pain in the ass) but it cleared the P0355 code
Car no longer stalls, hope it last

I notice that location varies with engine size and model of sentra

Thanks

Yes, different engine would have different location for sensors.

Well done.

I think for the cam and P0335 for the crank sensor circuit. I changed the cam rode great three days the started dying randomly with no warning. It felt like I had just let my foot off the gas but did not it just quit running. Changed crank and then changed the crank again because Autozone said it had to be done at the same time now it wont start. When taking the original crank sensor out the plastic casing that covers the wired prongs that you test popped off and you could see the prongs, but the other half of the sensor was still in the car finally got that off and saw the pigtail harness connector whatever you want to call it the clip not the part that goes on the sensor just the clip part was broken off. well we zip tied it to the sensor and tried to start it and it would not start it would crank it has fuel going to it. fuel pressure is right fuel relay is fine cleaned maf it is great. it is getting spark no plugs are fouled or coils messed up anything. I so not know what to do anymore. And we cannot put the old one back in because it is totally messed up, so I do not know if I should get a new ECM or what because it is still giving me the code P0335 circuit malfunction A. like I said before I changed the old sensor it was running, but it would just completely quit running or quit intermittently. P0335 Help!

Crank sensor circuit malfunction means that the connector or the wires from it to the ECM are the problem. You can get a new connector pigtail and replace the old one. Probably nothing wrong with either sensor just a wiring fault.

Looking at the wiring diagram, they both share the same ground and bias voltage feed. But the bias voltage also feeds other sensors so it is likely to be the ground wire. On both it is the black wire. They both show a connection on the intake manifold as the ground point.
Trace the wires through the harness and remove and clean that ground connection. Also, use a test light connected to battery positive to test the grounds at both sensors.
