P0013: Camshaft Position Actuator Circuit (Bank 1)
The P0013 code indicates a malfunction in the electrical circuit of the camshaft position actuator solenoid (also known as Variable Valve Timing solenoid) on Bank 1. This solenoid controls oil flow to the camshaft phaser to adjust valve timing. The Powertrain Control Module (PCM) detects an open, short, or excessive resistance in the circuit. Common causes include a faulty solenoid, wiring issues, low engine oil, or a clogged oil control valve.
01. Most Common Causes
- Faulty camshaft position actuator solenoid
- Open or shorted wiring in the actuator circuit
- Low or dirty engine oil
- Clogged oil control valve or passages
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Reduced engine power or poor acceleration
- Decreased fuel economy
- Engine may stall or hesitate
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect wiring and connector for damage, corrosion, or loose pins.
Step 3: Test the actuator solenoid resistance with a multimeter (typically 6-12 ohms).
Step 4: Check engine oil level and condition; replace if dirty or low.
Step 5: Clear code and test drive; if code returns, replace the solenoid.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause poor engine performance, increased emissions, and potential damage to the camshaft phaser or timing chain.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for a DIY solenoid replacement, or $200 to $400 at a shop including labor.
