ŚredniCamshaft Position Actuator (Intake) – Park Position, Bank 1. The engine control module has detected that the variable valve timing (VVT/VCT) actuator on the intake camshaft in bank 1 is not returning correctly to the neutral (park) position.
OBD-II (EN): Intake Camshaft Position Actuator Parking Position Bank 1
Code P2955 indicates that the variable valve timing (VVT) actuator on the intake camshaft is not returning to the park position – most often due to contaminated engine oil or a faulty OCV solenoid. Ignoring the fault can lead to accelerated timing system wear or engine damage. Prompt diagnosis at an authorized service center or a mechanic with a suitable diagnostic scanner is recommended.
Symptoms
Check Engine Light (MIL) on; difficult engine starting, especially when cold; rough engine idle; noticeable decrease in power and torque; worsened fuel consumption; possible knocking or metallic noise from the cylinder head area during cold start; in extreme cases, timing misalignment causing jerking during acceleration.
Possible causes
• Contaminated or aged engine oil blocking the VVT actuator hydraulic passages • Faulty or stuck variable valve timing control solenoid (OCV/CVVT solenoid) • Worn or damaged intake camshaft actuator (timing phaser) – mechanical seizure in a non-park position • Low oil pressure (worn oil pump, clogged oil filter) preventing proper VVT hydraulic system operation • Fault in the wiring harness or connector at the solenoid (short, open circuit, oxidized contacts)

The code alone is not enough. To find the cause, you need to read live data, check freeze frame conditions, and compare with vehicle behavior. Book a diagnostic session.
