Camshaft Profile Control Circuit Low Bank 1
The P002B code indicates that the powertrain control module (PCM) has detected a low voltage condition in the camshaft profile control circuit for bank 1. This circuit controls the variable valve timing (VVT) solenoid, which adjusts camshaft timing for optimal performance and emissions. A low voltage signal suggests a wiring issue, faulty solenoid, or PCM problem, potentially leading to poor engine performance and increased emissions.
01. Most Common Causes
- Faulty camshaft profile control solenoid (VVT solenoid)
- Open or shorted wiring in the control circuit
- Poor electrical connection at the solenoid or PCM
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Reduced engine power and fuel economy
- Failed emissions test
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect wiring and connectors for damage or corrosion.
Step 3: Test the camshaft profile control solenoid resistance and voltage supply.
Step 4: Check for continuity and shorts in the circuit between PCM and solenoid.
Step 5: If all else is fine, suspect a faulty PCM and perform further diagnostics.

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, reduced fuel economy, and potential damage to the catalytic converter.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, depending on the root cause. Replacing a solenoid may cost $100-$200 including parts and labor.
