P0080 Exhaust Valve Control Solenoid Circuit High Bank 1

P0080 points to a high exhaust valve control solenoid circuit on bank 1. The exhaust VVT circuit is open, shorted to voltage, or above expected range.

Code details

Generic OBD-II · P0

System: Fuel / Air
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace the camshaft actuator before isolating the high solenoid circuit fault.

Symptoms of P0080

Check-engine light on, sometimes with rough or uneven running.
Hesitation, surging, or a noticeable change in fuel economy.
Occasionally hard starting or a smell of unburnt fuel.

Common causes of P0080

A failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor).
Intake or vacuum leaks, or an exhaust leak near an upstream sensor.
Wiring, connector, or fuel-delivery problems that skew the reading.

Useful checks before replacing parts

Check solenoid signal voltage, feed supply, ground path, open circuits, short-to-voltage faults, connector fit, and solenoid resistance.
Inspect wiring near exhaust heat, oil-soaked connectors, terminal tension, shared VVT feeds, and recent timing or valve-cover service.
Compare high circuit events with commanded cam timing, actual exhaust cam angle, and related VVT or correlation codes.
