Fault code P0013 – a step-by-step guide to diagnosing and fixing it

Error code P0013 is displayed and the check engine light is on - what does this mean?

DTC P0013 is recognized by the OBD system when there is a problem with the camshaft position control on the exhaust side (bank 1). This error code indicates that the engine control unit has detected a malfunction in the camshaft phasing system, which is responsible for optimum valve timing.

What causes can this error code have?

• Defective camshaft phaser on the exhaust side
• Blocked or defective solenoid valve for the camshaft phasing unit
• Low engine oil pressure or incorrect engine oil
• Damaged wiring to the camshaft phasing system
• Defective camshaft sensor
• Blocked oil ducts in the camshaft phasing system
• Faulty timing chain or timing belt
• Defective engine control unit

What symptoms occur in parallel with fault code P0013?

• Loss of engine power: Noticeable reduction in engine power, especially at higher engine speeds
• Uneven idling: The engine runs unevenly at idle speed
• Increased fuel consumption: Significantly higher consumption due to inefficient combustion
• Starting problems: Difficult cold starts or prolonged cranking
• Metallic noises: Rattling or rattling noises from the engine compartment
• Check engine light: Permanent activation of the check engine light

How can the problem with error code P0013 be rectified?

• Repairing error code P0013 requires a systematic approach to identify the exact cause.
• Change the engine oil: Complete oil change with manufacturer-specific engine oil of the correct viscosity, as incorrect or contaminated oil is often the cause
• Replace camshaft phasing valve: Replace the defective solenoid valve for the camshaft adjustment, which is responsible for hydraulic control
• Check wiring and plugs: Check and repair damaged cables and clean corroded plug connections to the adjustment system
• Replace camshaft phasing unit: Complete replacement of the mechanical adjustment system in the event of irreparable damage to the adjuster itself
• Check oil pressure system: Diagnosis and repair of oil pump or clogged oil filter to ensure adequate system pressure
• Replace timing chain/timing belt: Replace worn drive elements that may affect the camshaft position
