P0080

Exhaust Valve Control Solenoid Circuit High Bank 1

Fuel & air metering Generic OBD-II High

What it means

P0080 means the engine computer detected an abnormally high voltage in the bank 1 exhaust valve control solenoid circuit — typically a short to voltage, an open, or a failed solenoid. This solenoid operates a variable exhaust/valve control feature, so the fault is electrical and usually affects performance rather than stopping the engine.

High

Can I keep driving? Usually drivable — the engine runs, though you may notice reduced performance or rougher running on engines that rely on the exhaust valve control.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Short to voltage or open in the exhaust valve control solenoid circuit
  2. Failed exhaust valve control solenoid
  3. Damaged, loose, or corroded connector at the solenoid
  4. Chafed or pinched wiring pulling the signal high
  5. Faulty engine control module (ECM) — rare

How to diagnose & fix

Work through it in order

  1. Read freeze-frame data and note any companion valve-control codes.
  2. Inspect the exhaust valve control solenoid connector and wiring for a short to voltage or damage.
  3. Measure the solenoid resistance and check its control and ground circuits against spec.
  4. Repair shorted or chafed wiring and clean corroded terminals.
  5. Replace the solenoid if it fails testing; consider the ECM last. Clear and re-test.

FAQ

Quick answers

Is it safe to drive with P0080?+
Usually yes for short trips. The engine still runs, but performance may suffer on engines that use exhaust valve control, so repair it soon.
Can I just clear P0080?+
A circuit-high fault is electrical, so clearing it is temporary — it returns until the wiring, connector, or solenoid is fixed.
