P001E: Camshaft Profile Control Circuit Low Bank 2
The P001E code indicates that the powertrain control module (PCM) has detected a low voltage condition in the camshaft profile control circuit for Bank 2. This circuit controls the variable valve timing (VVT) solenoid, which adjusts camshaft timing for optimal performance. A low voltage reading suggests a short to ground, open circuit, or faulty component in the system, potentially affecting engine timing and performance.
01. Most Common Causes
- Faulty camshaft profile control solenoid (VVT solenoid) on Bank 2
- 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
- Possible engine stalling
03. 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 the Bank 2 camshaft profile control solenoid for damage or corrosion.
Step 3: Test the solenoid resistance with a multimeter; compare to manufacturer specs.
Step 4: Check for voltage and ground at the solenoid connector with the engine running.
Step 5: If wiring and solenoid are okay, test the PCM output circuit for continuity and shorts.

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 or engine.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on the cause. Replacing a VVT solenoid is usually $50-$100, plus diagnostic time.
