Mazda 3 Fuel Vapor Leak Detection Pump

1 item

A fuel vapor leak detection pump helps the evaporative emissions system check for leaks. Depending on the vehicle's design, it participates in a test that monitors the sealed vapor system rather than supplying fuel to the engine.

Fuel Vapor Leak Detection Pumps

A fuel vapor leak detection pump helps the evaporative emissions system check for leaks. Depending on the vehicle's design, it participates in a test that monitors the sealed vapor system rather than supplying fuel to the engine.

A-Premium offers replacement detection pumps for selected vehicles. The pump must match the emission-system design, electrical connection and hose ports.

Choosing An EVAP Leak Detection Pump

Compare the electrical connector, port positions, mounting and application notes with the original component. Two pumps can have the same number of ports and still use different electrical connections.

An EVAP fault code can indicate a leak in a hose, connection or other part of the vapor system. Diagnose the actual fault before replacing the pump.

Frequently Asked Questions (FAQ)

Does the leak detection pump deliver fuel to the engine?

Its role is emissions-system monitoring, not engine fuel delivery. A fuel supply pump moves fuel through the fuel system; the leak detection pump is part of the vapor-system test.

Does a leak detection pump always create a vacuum in the EVAP system?

Test methods vary by design. Audi describes a vacuum-driven diaphragm pump on certain Q7 vehicles that pressurizes the EVAP system and monitors pressure loss; vacuum driving the pump is different from the pressure used in that test.

Is the filter included with the pump?

Package contents depend on the part. Three listed A-Premium examples specify that a filter is not included, so check the required filter and connections for the selected application.

Can a two-terminal pump replace a three-terminal pump?

The connector and circuit need to match the vehicle. The collection contains both two-blade and three-blade designs, which should be selected by application rather than substituted by appearance.

Does a small EVAP leak code prove the pump is faulty?

The code identifies a detected leak, not necessarily its exact location. Audi notes that its small-leak code can arise from a leak in the vapor system or at the detection pump; follow the vehicle's diagnostic procedure.
