P0010 — Camshaft A actuator control circuit/open, bank 1

P0010 identifies the bank 1 camshaft A actuator circuit, normally the intake cam. It indicates an electrical control fault, without proving chain wear or a failed CMP sensor. Confirm component location for the engine.

Affected system: Powertrain

Symptoms

• Check-engine lamp, sometimes without obvious running changes.
• Possible hard starting, uneven idle, hesitation or reduced power.

Possible causes

• Open wire or loose/corroded actuator connection.
• Open solenoid winding; supply or driver fault, subject to testing.

What to check

• Record codes and freeze-frame; distinguish P0010 from position/correlation codes.
• Locate the bank 1 intake actuator A and pins from OEM diagrams.
• With ignition off, inspect pins, oil contamination and harness chafing.
• Test supply, continuity and insulation as instructed with modules isolated; use engine-specific solenoid specifications.
• Run an authorised actuator test and check circuit feedback; verify repair under the original conditions.

Also written as: P0010-00, P001000, PO010 (some scan tools add the fault-type byte, e.g. -00).
