P0010 — “A Camshaft Position Actuator Circuit/Open (Bank 1)”.

—

🚗 Meaning of P0010

This code indicates a problem in the VVT (Variable Valve Timing) system — specifically with the intake (Camshaft ‘A’) actuator circuit on Bank 1 (the side of the engine with Cylinder 1).

The ECM (Engine Control Module) has detected that the electrical circuit controlling the camshaft actuator is open (broken or disconnected).

—

⚙️ Common Causes

1. Faulty VVT solenoid / Oil control valve (OCV)

2. Damaged wiring or loose connector at the solenoid

3. Low or dirty engine oil

4. Short/open in harness between ECM and VVT solenoid

5. ECM failure (rare)

—

🔍 Diagnostic Steps

1. Check engine oil level & condition

Low or dirty oil can prevent proper actuator function.

Change oil and filter if dirty or overdue.

2. Inspect VVT solenoid (OCV)

Unplug and visually check for corrosion, oil intrusion, or damage.

Measure resistance (usually 6–12 ohms) using a multimeter.

Apply 12V directly to solenoid — it should click if working.

3. Check wiring harness

Look for broken wires, loose pins, or damaged insulation.

Test for power supply and ground at solenoid connector.

4. Scan live data (if scanner supports it)

Check camshaft advance angle and VVT solenoid command.

If solenoid is commanded but camshaft doesn’t move → mechanical or actuator issue.

5. Clear the code and test drive

After repairs, clear code and run engine.

See if P0010 returns.

—

🧰 Typical Repairs

Replace VVT solenoid (most common fix)

Repair/replace damaged wiring or connector

Change engine oil & filter

In rare cases, replace ECM
