Description of DTC code P0336

The sensor CKP (Crankshaft Position Sensor by its acronym in English) usually has two cables. One is a signal, while the other is land. This sensor is a permanent magnet generator, which is located in front of a gear wheel on the top of the crankshaft.

When the reluctant wheel passes in front of the Crankshaft Position Sensor (CKP), a DC signal is emitted, which changes according to the engine speed. This DC signal is used by the PCM (Powertrain Control Module) to complete the motor RPM. The reluctant wheel of the crankshaft has a specific amount of teeth, and therefore the Power Train Control Module (PCM) can determine the position of the crankshaft, taking into account the pattern of this sensor. It should be noted that, the CKP sensor is also used in order to check misfiring of the cylinder, through certain measurements of the locations of the teeth of the reluctant wheel in the signal of the CKP sensor.

Basically this code means that the PCM has detected a signal loss from the CKP sensor. This loss can be momentary or total loss.


Symptoms of fault code P0336

  • Check Engine light on.
  • The engine may not start.
  • Misfiring that is intermittent.

Causes of OBD2 P0336

The factors that can lead to the establishment of fault code P0336 OBD2 are:

  • The teeth of the reluctant wheel may be worn.
  • Remains of magnet from the Crankshaft Position Sensor may be blocking the sensor or the reluctant wheel.
  • Cables or connectors related to the Crankshaft Position Sensor may be defective, thus causing a short circuit.
  • CKP sensor Defective.
  • CMP sensor defective.

Possible solutions of the DTC code P0336

You must do the following for the correct repair of diagnostic code P0336:

  • The failure may be intermittent, if that is the case and the engine does not start, you must observe with an endoscope or tachometer, to verify the RPM. If the RPM is not present, make sure there is a signal from the CKP sensor.
  • Check all cables of the Crankshaft Position Sensor (CKP). The problems can be caused by worn wires or that are very close to other components, such as spark plugs. Also check that there are no false connections, repair or change as necessary.
  • You must obtain a specification regarding the resistance of the CKP sensor, then verify if it is present. If not, change the Crankshaft Position Sensor.
  • If the level of resistance is adequate, check that the reluctant wheel has no damage such as broken teeth or the presence of other elements. Similarly, the ring should be just above the crankshaft, repair or change.
