P0082
UniversalIntake Valve Control Circuit Low (Bank 2)
The engine computer has detected a low electrical signal in the intake valve control circuit for Bank 2. The intake valve control system manages intake valve operation, and its electrical circuit is monitored by the computer. A low signal can result from a wiring or connection problem, an actuator fault, or a control-system issue. This code identifies a detected condition, not proof that a particular part has failed.
⚠️ Before You Begin (Safety First)
If the engine runs very roughly, stalls, loses significant power, or is difficult to control, stop driving when safe and arrange a diagnosis. If there are no serious drivability problems, seek diagnosis soon and avoid demanding driving until the cause is known. Do not probe electrical circuits without vehicle-specific service information.
Common Symptoms
- The check-engine light may be on because the computer detected a circuit condition.
- There may be no noticeable change in how the vehicle runs.
- Rough running or an unstable idle may occur if intake valve operation is affected.
- Reduced power or slower response may occur if the system cannot control intake valve operation as intended.
- Fuel economy or emissions may worsen if engine operation is affected.
Common Causes
- Damaged wiring or a short to ground in the Bank 2 intake valve control circuit may pull the signal low.
- A loose, corroded or damaged connector may interfere with the circuit.
- The intake valve control actuator or solenoid may have an internal electrical fault.
- A problem in the circuit's power supply, ground or control path may cause the detected low signal.
- A fault in the engine computer's control circuitry is possible, but should be considered only after the circuit and actuator are checked.
Diagnostic Steps
- Record the code and any related codes before clearing anything; related codes can help show whether the issue affects a broader circuit or system.
- With the vehicle parked safely and the engine off, look for visibly damaged wiring or a loose, corroded or damaged connector in the intake valve control wiring, if it is safely accessible.
- Check the vehicle's owner information for any recent symptoms or warning messages, and note whether the engine runs roughly, stalls or loses power.
- Avoid replacing the actuator based on this code alone. Bank identification and circuit tests depend on the specific engine, so use model-specific service information or have a technician test the circuit.
When to Call a Professional
Use vehicle-specific service information to identify the Bank 2 circuit and its test procedure. A technician can inspect scan data and related codes, then check the connector, wiring, circuit signals, actuator and computer control as appropriate. Confirm the cause before replacing parts; exact tests depend on the model, year and engine.

Commonly Asked Questions
Does P0082 prove the intake valve control actuator is bad?
No. It indicates a low signal detected in the Bank 2 intake valve control circuit. Wiring, connectors, the circuit's power or control path, and the actuator itself may need to be checked.
What does Bank 2 mean for this code?
Bank 2 identifies the engine bank associated with the detected circuit condition. Its location depends on the engine, so consult vehicle-specific service information rather than guessing.
Can I keep driving with P0082?
The effect varies. If the engine runs normally, arrange diagnosis soon and avoid demanding driving. If it stalls, runs very roughly or loses significant power, stop driving when safe and seek assistance.
Could the code appear even if the engine seems normal?
Yes. A monitored circuit condition may be detected before an obvious change in performance, and some vehicles may show no noticeable symptoms.
