EVAP Leak Detection Pump Control Circuit Open

Moderate severity

What it means

The control circuit to the EVAP leak-detection pump is open. Without that pump the ECU cannot pressurise the fuel-vapour system to test for leaks.

Is it safe to drive?

Use caution

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
