P002D: Camshaft Profile Control Circuit/Open Bank 2
Code P002D indicates a problem in the camshaft profile control circuit for Bank 2, typically on engines with variable valve timing (VVT) or cylinder deactivation. The Powertrain Control Module (PCM) detects an open or short circuit in the solenoid or wiring that controls the camshaft profile switching. This can lead to improper valve timing, reduced engine performance, and increased emissions.
1. Most Common Causes
- Internal open circuit in the Bank 2 camshaft profile actuator solenoid 'B'
- Damaged, cut, or disconnected wiring between the ECM and the actuator solenoid
- Corroded, loose, or damaged pins in the solenoid connector
- Excessive circuit resistance due to poor splices or terminals
- Internal ECM failure in the solenoid driver circuit (less common)
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: Scan for codes and record freeze frame data.
Step 2: Visually inspect the camshaft profile control solenoid and wiring for damage or corrosion.
Step 3: Test the solenoid resistance with a multimeter (compare to specs).
Step 4: Check for voltage and ground at the solenoid connector with the engine running.
Step 5: If wiring and solenoid are OK, test the PCM output circuit.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause engine performance issues and potential damage to the camshaft or timing components.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, depending on whether the solenoid or wiring needs replacement.
