P0083
UniversalIntake Valve Control Circuit High (Bank 2)
Medium SeverityThis code indicates that the engine's computer (PCM) has detected a high voltage condition in the circuit for the Intake Valve Control system on engine bank 2. This typically means the variable valve timing (VVT) or variable valve lift (VVL) system for the intake valves on that bank is not functioning correctly, which can impact engine performance and fuel efficiency.
⚠️ Before You Begin (Safety First)
Always ensure the vehicle is parked on a level surface with the parking brake engaged before performing any work. Allow the engine to cool down to prevent burns. Always disconnect the battery before working on electrical components to avoid electrical shock or damage to the vehicle's systems.
Common Symptoms
- Check Engine Light illuminated
- Rough idle
- Reduced engine performance
- Decreased fuel economy
- Engine hesitation or misfires
Common Causes
- Faulty Intake Valve Control Solenoid (VVT/VVL solenoid)
- Open or short in the solenoid wiring harness
- Poor electrical connection at the solenoid
- Faulty Engine Control Module (ECM) or Powertrain Control Module (PCM)
- Damaged intake valve control actuator
Frequently reported on: General/Universal, Honda CR-V (2007-2011), Toyota Camry (2002-2006), Nissan Altima (2007-2012)
Diagnostic Steps
- Retrieve and confirm the P0083 code using an OBD-II scanner.
- Visually inspect the wiring harness and connectors for the Intake Valve Control Solenoid on Bank 2. Look for signs of damage, fraying, or loose connections.
- Disconnect the battery. Check the electrical connector for corrosion or bent pins and clean or repair as necessary.
- If comfortable, use a multimeter to check for continuity and proper voltage at the solenoid connector (refer to vehicle-specific repair manual for exact specifications). A 'High' circuit fault often points to an open circuit or a short to voltage.
- Clear the code and test drive the vehicle to see if the code returns.
👨🔧 When to Call a Professional
If basic diagnostic steps like checking connections and inspecting wiring do not resolve the P0083 code, or if you lack specialized electrical diagnostic tools like a multimeter, it is best to consult a professional mechanic. Advanced diagnostics are often required to pinpoint electrical circuit issues or internal component failures.
Commonly Asked Questions
What does 'Bank 2' mean for P0083?
Bank 2 refers to the side of the engine that does not contain cylinder #1. On V-type or Boxer engines, it's typically the opposite bank from Bank 1. On inline engines, this code usually refers to a specific intake valve group if applicable.
Can I drive with a P0083 code?
While you might be able to drive, it's not recommended for extended periods. The issue with the intake valve control can lead to reduced engine performance, decreased fuel economy, and potentially cause further engine damage over time if not addressed.
Is the Intake Valve Control Solenoid expensive to replace?
The cost of an Intake Valve Control Solenoid (VVT/VVL solenoid) can vary widely by vehicle make and model, typically ranging from $50 to $200 for the part itself, plus labor if professionally installed.
How can I test the Intake Valve Control Solenoid?
Testing the solenoid usually involves checking its electrical resistance with a multimeter and applying a small amount of voltage to ensure it actuates correctly. Refer to your specific vehicle's service manual for detailed testing procedures and specifications.
Could a P0083 code be caused by low oil levels?
Yes, in some variable valve timing (VVT) systems, the solenoids rely on engine oil pressure to operate. Low or dirty engine oil can sometimes impact the functionality of these solenoids, leading to a P0083 code. Always ensure your engine oil is at the correct level and clean.
