P0335 – Meaning, Causes, Symptoms, & Fixes

Reading Time: 2 minutes

Code P0335 Definition

Crankshaft Position Sensor “A” Circuit Malfunction (Bank 1)

What Does P0335 Mean?

Crankshaft position is used to inform the Engine Control Module (ECM) of when it is time to spark and deliver fuel. It works hand in hand with the reluctor ring that creates a square wave voltage signal that the ECM interprets as the crankshaft position. Trouble code P0335 is set whenever the ECM does not sense crankshaft pulses or senses a problem with the pulses in the output with Sensor “A” Bank 1.

P0335 Symptom

  • Check Engine Light
  • Vehicle may stall/hesitate
  • Hard starting vehicle
  • Rough running vehicle
  • Engine dies

P0335 Causes

  • Damaged crankshaft position sensor
  • Defective crankshaft position sensor
  • Broken timing belt or chain
  • Rough running/misfiring engine
  • Failed ECM

Code P0335 Severity – High


This trouble code can cause some major internal mechanical drivability issues. To prevent any further damage to the engine, diagnosis should be done as soon as possible to fix the issue.

Code P0335 Common Diagnosis Mistakes

The crankshaft position sensor is replaced whenever there is a defective camshaft position sensor or a poor connection.

P0335 Diagnosis

  • Tools Needed to Diagnose:
    • FIXD

Difficulty of Diagnosis and Repair – (4-7)*

  1. Use live scan tool to check that there is a RPM reading when the engine is running.
  2. Conduct a visual inspection of the crank sensor and connectors and search for signs of fraying/damage to the wiring.
  3. If no visible damage is found, you can check the CKP 5 Volt square wave pattern. You will have to reference your vehicle’s repair manual to determine which resistance reading is sufficient. This reading will come from the vehicle’s PCM. If you are not familiar with vehicles, it is best to leave this step to a professional.
  4. If the reading is within the specifications of the vehicle, no need to replace the crankshaft position sensor. However if the reading is NOT within the specifications of the vehicles, the crankshaft position sensor should be replaced. Replace any frays/damaged wiring and if the reading is within the specifications now, there may be a short in the wiring.

*If these steps do not locate your issue, it may be within your PCM and you will need to take it to a mechanic for further diagnosis.

  1. all of the diagnostics that my fixed has come up with are valid. thank you for the help.

    1. I have purchased a new very expensive reader, for nothing because my FIXD reader does exactly the same job and better.im very pleased with it, it’s a great tool everyone should own.

  2. Excellent to understand about cks

  3. My diagnosis came while my car would not start and had no dash lights. AAA said it was the starter and my mechanic confirmed that.

  4. I have a 2006 Chevy Impala with the 3.5 and the p0335 code stays on even after changing the crank position sensor i also checked for voltage at the plug and it is good as well..so I’m thinking possible ECM problem?

    1. I have a 2006 Nissan Xterra the car will start up run for 10 15 20 minutes then die turn it off then I have to wait 2 to 10 minutes will turn back on like nothing run perfectly good for another 20 minutes and repeat turns off and does the same thing I had been put on that Snap-on diagnostic machine and for colds came out what could be my problem code p0035 came out code P0 420 came out code p0057 came out cold p0436 came out as well what could be my problem

  5. I am having the same problem. A camshaft position sensor just came up now so I will try replacing that also.

  6. Cleared code to check if still cuing purchased new sensor and replaced issue resolved

    1. So I Replaced both Camshaft and Crankshaft sensor’s within a week and less then 2 months ago I replaced the throttle body sensor and I still get the P0335?? this is on a 2007 GMC Yukon. and it cranks for a while to start? any help would be appreciated thanks

      1. Check wiring harness.

      2. My PO335 says, most likely solution is: replace flywheel. Is this right?

  7. I have being battling with a stalling/misfiring engine for months now. And its being drainging my pocket because i have to frequently visit the mechanic. A 2000 Sonata. Ive changed fuel pump cos it seem the problem gets worse when the engine heats up and will have to wait some minutes before engine can start. Ive had my spark plugs and coils checked and its Ok. but problem still remained. A month ago the OBD2 scanner gave an ECT sensor error. I replaced that too. Works well for a while and problem resurfaces. Recently i was having a tough time starting it in the mornings and sometimes in the day even after moving it around some few miles.

    Then the Mechanic said there was no power distribution so he suspects the Crankshaft sensor. This was then confirmed by the OBD 2 scanner. i got it too replaced and for some 4 days now its running better. Just hoping thats it with the misfire and difficulty in starting problem

    But one other problem exist and cant tell how to solve it yet
    My speedometer sometimes works and sometimes too stays at zero

    1. My check engine light hasnt shown up all this while

  8. I need help i have 04 civic and the check engine light is on, it shoes that my crankshaft sensor is bad. I already replaced the crankshaft sensor and also the camshaft sensor but its still not coming off. Any help please

  9. I had a po335, replaced the crankshaft position sensor, still having some problems. A few minutes after I put my engine back together, turned my car on idled fine and then just shut off. I turned it back on and every time I gave it gas it bogged down. The next day I was able to drive it but it would randomly cut off, soon it slowly lost power and struggle to accelerate or shift. I dont know what to do

    1. Hi,you didnt say what make and model of your car. Is it automatic or manual? Before you did some work on your engine,was this problem oresent? What work was done on the engine?

      1. Hi my name is Kate and my problem is with my 2011 Toyota kluger, it started smoking about3 weeks ago when I turned it on then it goes away it hasent lost power it is still smooth to drive the Toyota place told me that the problem is in the motor and that they would have to pull it apart and that it may be the rings it has done 173000kms and the cost to fix it would be around ten thousand they told me because I wasn’t on time with the last service the oil went bad and I damaged the motor, just today I have noticed the engine light has come on, a lot of smoke comes out of the exhaust when I first start it up white smoke then it goes away can you help me and it is automatic thank you


  11. i have a nissan sunny FB15 and its showing P0335 fault. i replaced the crankshaft position sensor but engine fails to start whilst the sensor is coonected. once i disconnect the crank-sensor it will start but will not give enough power when driving. Engine may stall anytime. As of now if i replace the CKS from another car which is moving, it will not start until i disconnect the sensor harness.

    A proffessional tried to check the wiring but he said it was fine. Am now thinking faulty ECM.

    Can Anyone help +263772716030

  12. My PO335 says, most likely solution is: replace flywheel. Is this right?

  13. 2009 Dodge journey 2.4 liter. P0335 has been showing for months, no matter what we replace. Started with crankshaft position sensor, cylinder 1, spark plugs. Thought the problem was fixed and then it started running bad again, took it back and still showed P0335. So far, we have changed reluctor wheel, timing chain, crankshaft position sensor, spark plugs, cylinder, coil, battery….problem still persists. Now it will not start at all, almost like a dead battery…? It’s our only vehicle and we have a little one and jobs, any advice would be welcome.

  14. I have a 6.2 LS swap crank sensor code p0335 takes 5 times cranking to start, tach not working Replaced crank sensor still have code and still same symptoms. I have 5 volts on pin a good ground on b and some reason 5 volts on signal wire. Any ideas? Thanks!

  15. 2.4 RT . Crankshaft sensor error and random misfire.

    Issue was resolved with a new sensor and new plugs

  16. p0035 is a turbocharger code. you may have gotten that one wrong. the others are related to either an o2 sensor, or a bad catalytic converter

  17. Replaced Cam Position Sensor, Crankshaft Position Sensor, and the wiring loom connected to the cam sensor.
    After 2 days of driving with no issues, am getting p0335, although there is no detectable problems when starting or driving.
    Any ideas?
