Code Definition

P0080 — Exhaust Valve Control Solenoid Circuit High (Bank 1)

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

About P0080

P0080 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 P0080 is stored, the module has detected a signal or supply voltage higher than the expected operating range; and 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 P0080 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 P0080 code indicates a high voltage condition in the control circuit of the exhaust valve control solenoid for Bank 1. This solenoid is part of the variable valve timing (VVT) system in the engine, controlling the timing of the exhaust valves. The Engine Control Module (ECM) sets this code when it detects a voltage in the solenoid circuit that is higher than expected. A high voltage situation can affect the operation of the VVT system, impacting engine performance, emissions, and fuel efficiency.
