Intake Valve Control Solenoid Circuit Low (Bank 2)
The P0082 code indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the intake valve control solenoid circuit for Bank 2. This solenoid is part of the variable valve timing (VVT) system, which adjusts intake valve timing to optimize engine performance and emissions. A low circuit condition typically means the voltage signal from the solenoid is below the expected range, often due to a short to ground, faulty solenoid, or wiring issues. Bank 2 refers to the side of the engine opposite cylinder #1.
1. Most Common Causes
- Faulty intake valve control solenoid (Bank 2)
- Short to ground in the solenoid circuit
- Open or damaged wiring/connector
- Corroded or loose electrical connections
- Failed PCM (rare)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Reduced engine power and fuel economy
- Failed emissions test
3. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P0082 is present. Check for additional codes.
Step 2: Visually inspect the wiring and connector for Bank 2 intake valve control solenoid for damage, corrosion, or loose connections.
Step 3: Use a multimeter to test the solenoid resistance (typically 6-12 ohms). Compare to manufacturer specs.
Step 4: Check for voltage at the solenoid connector with the engine running (should be battery voltage). If low, trace circuit for shorts or opens.
Step 5: If wiring and solenoid are good, test the PCM output signal. Replace PCM if necessary.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause reduced engine performance, poor fuel economy, and potential damage to the VVT system. Have it diagnosed promptly.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts and labor. The solenoid itself costs $50-$150, and labor adds $100-$250 depending on vehicle accessibility.
