P0082 – Intake Valve Control Solenoid Circuit Low (Bank 1)

Description

The P0082 trouble code indicates that the Engine Control Module (ECM) has detected a low voltage condition in the intake valve control solenoid circuit on Bank 1. The intake VVT solenoid controls oil flow to the variable valve timing system, which adjusts intake valve timing to improve engine performance, fuel economy, and emissions.

Common Causes

• Faulty intake VVT control solenoid.
• Short circuit to ground in the wiring.
• Damaged or corroded connector.
• Open or damaged electrical circuit.
• Low or dirty engine oil.
• Faulty ECM (rare).

Symptoms

• Check Engine Light ON.
• Loss of engine power.
• Rough idle.
• Poor acceleration.
• Higher fuel consumption.

Estimated Repair Cost

Repair costs usually range from $30 - $300, depending on whether the problem requires wiring repair, connector replacement, or a new intake VVT solenoid.

Severity

Moderate. The vehicle may still operate, but ignoring the problem can affect engine performance and variable valve timing operation.

Recommended Fix

Check the intake VVT solenoid, inspect wiring and connectors, test power and ground circuits, repair any electrical faults, replace the solenoid if faulty, clear the trouble code, and verify the repair.
