P002C: Camshaft Profile Control Circuit High Bank 1
The P002C code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the camshaft profile control circuit for Bank 1. 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. This can cause improper camshaft timing, leading to reduced engine performance and fuel economy.
1. Most Common Causes
- Faulty camshaft profile control solenoid (VVT solenoid)
- Short to power in the control circuit wiring
- Damaged connector or corroded terminals
- Failed PCM (rare)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Reduced engine power and acceleration
- Poor fuel economy
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for additional codes.
Step 2: Visually inspect the wiring and connector for Bank 1 camshaft profile control solenoid for damage, corrosion, or shorts.
Step 3: Test the solenoid resistance with a multimeter; compare to manufacturer specs (typically 6-12 ohms).
Step 4: Check for voltage at the solenoid connector with key on; should be battery voltage. If high, trace short to power.
Step 5: If wiring and solenoid are okay, test the PCM output; if faulty, replace PCM.
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 performance and potential engine damage. Limp mode may activate, limiting speed.
How much does it cost to fix?▼
Typically $50-$150 for diagnosis and solenoid replacement. PCM replacement can cost $500-$1000.
