P0083: Intake Valve Control Solenoid Circuit High (Bank 2)
The P0083 code indicates that the Powertrain Control Module (PCM) has detected a high 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 high voltage signal suggests a short to power, open circuit, or faulty solenoid, potentially causing drivability issues.
01. Most Common Causes
- Faulty intake valve control solenoid (Bank 2)
- Short to power in the solenoid circuit wiring
- Open or high resistance in the solenoid circuit
- Corroded or damaged connector at the solenoid
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine hesitation
- Reduced fuel economy
- Poor acceleration or loss of power
- Engine may stall or run erratically
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm P0083 and check for other codes.
Step 2: Visually inspect the intake valve control solenoid connector and wiring for damage, corrosion, or shorts.
Step 3: Measure the resistance of the solenoid (typically 6-12 ohms) and compare to specs.
Step 4: Check for voltage at the solenoid connector with key on; should be battery voltage on one pin.
Step 5: If wiring and solenoid are okay, test the PCM output signal; replace PCM if necessary.

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, increased emissions, and potential damage to the VVT system. Short trips to a repair shop are okay.
How much does it cost to fix?▼
The cost typically ranges from $150 to $400, including parts (solenoid $50-$150) and labor (1-2 hours at $100-$150/hour).
