Fault code P0336 – a step-by-step guide to diagnosing and fixing it

Error code P0336 is displayed and the check engine light is on - what does this mean?

The OBD/EOBD system detects an error in the crankshaft sensor signal, which is saved as DTC P0336 "Crankshaft Position Sensor A Circuit Range/Performance". This trouble code indicates problems with the crankshaft sensor or its circuit, as a result of which the engine control unit cannot correctly determine the exact position of the crankshaft.

What can cause this error code?

• Defective crankshaft sensor
• Damaged or corroded sensor cable
• Loose or dirty plug connections
• Defective sensor wheel on the crankshaft
• Incorrect sensor installation or alignment
• Dirt or metal chips on the sensor
• Defective engine control unit inputs
• Excessive air gap between sensor and sensor wheel

What symptoms occur in parallel with error code P0336?

• Starting problems: The vehicle is difficult or impossible to start because the ignition cannot be cycled correctly. Engine running unevenly: The engine runs unevenly, jerks or misfires while driving. Loss of power: Noticeable reduction in engine power and poor acceleration. Stalling: The engine stalls while driving or idling. Misfiring: Irregular ignition leads to noticeable vibrations and poor engine running.

How can the problem of error code P0336 be rectified?

• The repair requires a systematic diagnosis of the crankshaft sensor components.
• Replace the crankshaft sensor completely and align it properly, maintaining the correct air gap to the sensor wheel
• Check sensor cable and plug connections for damage, clean or replace completely if corroded
• Check the sensor wheel on the crankshaft for damage or missing teeth and replace if necessary
• Adjust the air gap between the sensor and sensor wheel to the manufacturer's specifications using a feeler gauge
• Check engine control unit for defective inputs and repair or replace if necessary
• Thoroughly clean the sensor and sensor wheel area to remove metal chips and dirt
