Hi, the code P0335 means the crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

Symptoms

  • Vehicle may not start
  • Vehicle may run rough or misfire
  • MIL illumination

Solution
  • Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.
  • If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?
  • If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?
  • If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.

Concerning the fuel smell in the cabin, gas leaks in the engine compartment or at the fuel tank can also cause you to smell gasoline. A leak at the gas tank fill tube or the evaporative fuel return lines will allow fuel vapor to enter the cabin. Leaks in the engine compartment not only vent fuel vapors into the cabin, but are also dangerous as they can result in fires. Common areas to find leaks are around the fuel pump, fuel injectors, carburetor, or fuel lines. Do not run a vehicle that has gasoline leaking in the engine compartment.

Sometimes my when I accelerate when I am stopped at a light my car will stall and cutoff. Other times when I am driving it lose power and shuts off.


IF YOU HAVE NO HARD START PROBLEMS, COLD OR HOT, I WOULD START WITH A PC SCAN FOR CODES, EMISSIONS TEST & FUEL PSI CK. IT COULD BE AS SIMPLE AS A VACUUM LEAK. THAN SCAN PC FOR CODES (TPS, IDLE SPEED SOLINOID. OR RUNS LEAN OR RICH- VAC LEAKS AIR/ GF, INJECTORS FUEL PSI ETC. START WITH THE BASICS. AIR, FUEL & SPARK/ TIMING. GOOD LUCK FRANK M

My 1993 Toyota Corolla stalls and will not stay running.


If changing the battery does not solve problem, or only solves it until the battery dies then have the alternator tested. I have noticed on several occasions with a couple of my vehicles that at times of very high moisture in the air they do not stay running, once the humidity goes down they are fine.

Stalling when turn back on


all stalls end in CEL check engine light on. that is normal
but CEL glow. when engine running , means you had a failure, and it stored DTC error codes, so scan it.
lots of causes. huge list.
get a tune up , tops list.

SCAN it to be sure all sensors work. running.
all fuses in car good.
by stalls , i assume the engine stalls and engine RPM is 0 RPM.
the stall cause the whole dash to light up, all the warning lamps come
on (self test) oil , charge , CEL. come on.
what is important is the stall and the cause.

i will tell you the 3 ways.
lost electrical power to engine EFI system (seems not)
bad engine, (lost compression hot)?
bad spark , spark died.?
bad fueling, lost all fueling (starves and stalls or floods and misfires horribly and stalls (black spark plug tips are big time clue)

if non eof the rings a bell.?
get the car serviced.

this car is newer nicer car, you (we) can scan and drive and log data.
allowing faster easy diagnosis.

02' Nissan Altima, car jerking, turns off at light, but turns right back on. Engine light on, code from autozone P0335 crankshaft position sensor. P0725 Engine speed signal circuit. The start up, days it...


If it has a code for loosing the crankshaft position sensor signal, I would certainly start looking at that before venturing into the fuel system. Cam and Crank sensors are a common failure item for Nissans of that era. Nissan actually redesigned the sensor and i think they performed a recall on some vehicles. They are fairly inexpensive and easy to replace. I believe they run about $40 each. Because most people don't have access to a powerful scanner or a digital storage oscilloscope to verify the failure I recommend replacing the cam and crank sensors at the same time.

You have a lot to check. Start by scanning the engine codes. There's good chance it will tell you where to look next.
The symptoms sound like fuel delivery (assuming the engine runs well when it runs). Put a fuel pressure gage on the car and verify that you are getting a constant and good pressure. Could be fuel pump, blocked lines, bad fuel regulator, or an intermittent electrical problem. I had a situation like this where the car would run fine and then just cutout or not start. Turned out to be a loose connection to the fuel pump. Easy fix. Very hard to find.

It surely sounds like you are confronted with a damaged cat converter. The o2 sensor is what triggers your ck eng ligh and it is located both up and downstream of the Converter. Won't hurt to have it chk'd. If there is a sulphur odor coming from the exhaust, The cat conv is bad. Good Luck, Ned

My experience in this makes me think that you have a rusted fuel line, at the top of the tank. This is a common problem. I remove the tanks and replace the fuel tank fuel line/bracket assembly quite a bit.

98Eclipse 2.0 nonTurbo 5speed 180,000 miles ,code PO301


The po301 is a misfire code. The backfire can be caused by a excessive amount of fuel, bad valve timing etc.
My guess is you have damage to an exhaust valve that may have occurred when you had the timing belt problem.A compression test will indicate if you have a leaking exhaust valve.The reason for the backfire is the exhaust valve is still partially open when the spark plug fires.

My 97 buick runs cold stalls when hot wont start for 1 hour


Sounds like it is fuel related. Ck fuel pressure to be sure. Also ck the pressure regulator on the fuel rail, It is a small metal cylinder at the end of the fuel rail to ck pull to vacumn line off (hot not running after shutting the engine off). If there is fuel in the vacumn line it is bad. Good luck
