Where is the vacuum cut valve bypass valve?

Where is the vacuum cut valve bypass valve?

The vacuum cut valve and vacuum cut valve bypass valve are installed in parallel on the EVAP purge line between the fuel tank and the EVAP canister. The vacuum cut valve prevents the intake manifold vacuum from being applied to the fuel tank. The vacuum cut valve bypass valve is a solenoid type valve and generally remains closed.

What does the vacuum cut valve on a Nissan Altima do?

The vacuum cut valve prevents the intake manifold vacuum from being applied to the fuel tank. The vacuum cut valve bypass valve is a solenoid type valve and generally remains closed. It opens only for on board diagnosis. The vacuum cut valve bypass valve responds to signals from the ECM.

Why is the vacuum cut valve not working?

Vacuum cut valve bypass valve does not operate properly. The vacuum cut valve and vacuum cut valve bypass valve are installed in parallel on the EVAP purge line between the fuel tank and the EVAP canister. The vacuum cut valve prevents the intake manifold vacuum from being applied to the fuel tank.

What does a vacuum cut valve on a fuel tank do?

The vacuum cut valve prevents the intake manifold vacuum from being applied to the fuel tank. The vacuum cut valve bypass valve is a solenoid type valve and generally remains closed. It opens only for on board diagnosis.

How does a vacuum cut bypass valve work?

The vacuum cut valve bypass valve is a solenoid type valve and generally remains closed. It opens only for on board diagnosis. The vacuum cut valve bypass valve responds to signals from the Engine Control Module (ECM). When the ECM sends an ON (ground) signal, the valve is opened.

What kind of valve is a vacuum cut?

The vacuum cut valve bypass valve is a solenoid type valve and generally remains closed. It opens only for on board diagnosis. The vacuum cut valve bypass valve responds to signals from the ECM.

What does the vacuum cut valve on a Nissan do?

The vacuum cut valve bypass valve responds to signals from the ECM. When the ECM sends an ON (ground) signal, the valve is opened. The vacuum cut valve is then bypassed to apply intake manifold vacuum to the fuel tank.

When does an EVAP valve need to be replaced?

When there is no signal (no power) the valve should be closed (cant blow through it). When you apply a 12 volt power source and ground the valve should open with a discernible click. If the valve does no perform this way it is bad and needs to be replaced.

What to look for in an EVAP system failure?

A technician will look for loose, missing, or damaged components. We will often wiggle wires and hoses while looking, listening, and even sniffing for changes. We’ll remove the gas cap and look for damage to the gas cap, o-ring, and filler neck. While reinstalling the gas cap we’ll pay close attention to how it fits.
