P002F: Camshaft Profile Control Circuit High Bank 2
The P002F code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the camshaft profile control circuit for Bank 2. This circuit controls the variable valve timing (VVT) solenoid or camshaft phaser actuator, which adjusts camshaft timing for optimal performance. A high voltage reading suggests a short to power, faulty solenoid, or wiring issue, potentially causing improper camshaft timing and reduced engine performance.
1. Most Common Causes
- Faulty camshaft profile control solenoid (VVT solenoid) on Bank 2
- Short to power in the wiring or connector of the solenoid circuit
- Corroded or damaged electrical connector
- Engine control module (ECM) failure (rare)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Reduced engine power and fuel economy
- Failed emissions test
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data. Clear code and test drive to see if it returns.
Step 2: Visually inspect the Bank 2 camshaft profile control solenoid wiring and connector for damage, corrosion, or shorts.
Step 3: Use a multimeter to check the solenoid resistance (typically 6-12 ohms) and compare to specs. Test for voltage at the connector with key on (should be battery voltage).
Step 4: If wiring and solenoid are okay, test the ECM output by commanding the solenoid on/off with a scan tool and monitoring voltage.
4. 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 components.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on whether the solenoid or wiring needs replacement. Diagnostic fees may add $50-$100.
