Code Definition

P0081 — Intake Valve Control Solenoid Circuit (Bank 2)

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0081

P0081 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0081 is stored, the module has detected a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0081 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0081 code indicates a malfunction in the control circuit of the intake valve control solenoid for Bank 2. This solenoid is a component of the engine's variable valve timing (VVT) system, which adjusts the timing and operation of the intake valves. The Engine Control Module (ECM) sets this code when it identifies an issue within the electrical circuit that controls the solenoid. Problems in this circuit can lead to suboptimal engine performance, affecting efficiency and emissions.
