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, which adjusts camshaft timing to optimize engine performance. A high voltage reading typically points to a short to power, faulty solenoid, or wiring issues.
01. Most Common Causes
- Faulty camshaft profile control solenoid (VVT solenoid)
- Short to power in the control circuit wiring
- Corroded or damaged connector at the solenoid
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine performance and fuel economy
- Rough idle or stalling
- Possible engine misfire
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the VVT solenoid connector and wiring for damage or corrosion.
Step 3: Test the solenoid resistance with a multimeter (specs vary by vehicle).
Step 4: Check for voltage at the solenoid connector with key on; if voltage is above 12V, repair short to power.
Step 5: If wiring and solenoid are good, test PCM output or replace PCM as last resort.

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 and potential damage to the catalytic converter.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on the vehicle and whether the solenoid or wiring needs replacement.
