P001E: Camshaft Profile Control Circuit Low Bank 2
The P001E code indicates that the engine control module (ECM) 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 to optimize engine performance. A low voltage reading suggests a short to ground, open circuit, or faulty component in the circuit, potentially affecting engine timing and performance.
1. Most Common Causes
- Short to ground in the Bank 2 cam profile control solenoid signal wire
- Open circuit in the solenoid voltage supply (VPWR) or ground circuit
- Bank 2 cam profile control solenoid/actuator (VCT/OCV) with internally shorted coil
- Damaged, corroded, or loose terminals in the actuator connector
- Low engine oil level or pressure (affects hydraulic feedback, though typically sets performance codes)
- Internal PCM/ECM driver failure
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Reduced engine power or poor acceleration
- Decreased fuel economy
3. Step-by-Step Diagnosis
Step 1: Scan for additional codes and freeze frame data to confirm P001E.
Step 2: Visually inspect the wiring and connector for Bank 2 camshaft profile control solenoid for damage, corrosion, or loose connections.
Step 3: Test the solenoid resistance with a multimeter; compare to manufacturer specs (typically 6-12 ohms).
Step 4: Check for voltage and ground at the solenoid connector with the engine running; should see battery voltage and a good ground.
Step 5: If wiring and solenoid are OK, test the ECM output by backprobing the circuit; if no signal, suspect ECM failure.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the engine may run poorly, stall, or cause further damage to the VVT system. Short trips to a repair shop are acceptable.
How much does it cost to fix?▼
Typical repair costs range from $50 to $150 for a DIY solenoid replacement, or $200 to $400 if professional labor is included.
5. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
