Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

- Remove the fuel fill cap.
- Disconnect the vapor line from the EVAP two-way valve (A), and connect a T-fitting (B) from the vacuum gauge and the vacuum pump/gauge, 0-30 in.Hg, to the hose as shown.
- Apply vacuum slowly and continuously while watching the gauge.
The vacuum should stabilize momentarily at 0.8-2.1 kPa (0.2-0.6 in.Hg, 6-16 mmHg).
If the vacuum stabilizes (valve opens) below 0.8 kPa (0.2 in.Hg, 6 mmHg) or above 2.1 kPa (0.6 in.Hg, 16 mmHg), install a new valve, and retest.
- Move the vacuum pump hose from the vacuum fitting to the pressure fitting, and move the vacuum gauge hose from the vacuum side to the pressure side (A) as shown.
- Slowly pressurize the vapor line while watching the gauge. The pressure should stabilize momentarily above 1.0 kPa (0.3 in.Hg, 8 mmHg).
- If the pressure momentarily stabilizes (valve opens) above 1.0 kPa (0.3 in.Hg, 8 mmHg), the valve is OK.
- If the pressure stabilizes below 1.0 kPa (0.3 in.Hg, 8 mmHg), install a new valve, and retest.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
