FAQ

This valve is compatible with a wide range of Mazda models, including the 626 (1993–2002), 929 (1992–1995), Millenia (1995–2002), MPV (1992–1998), MX-6 (1993–1997), Protege (1995–2003), Protege5 (2002–2003), and RX-8 (2004–2011).
This part replaces OEM number KL01-18-741. It also cross-references with part numbers 911-707, K5T49090, K5T49091, K5T49093, K5T49096, K5T49099, K5T19090, VS55, EVS189, and 226874.
Common signs of a faulty solenoid include an illuminated Check Engine Light (often associated with P0400 or similar EGR flow codes), rough engine idling, decreased fuel economy, or engine pinging/knocking during acceleration due to improper exhaust gas recirculation.
Before replacing the solenoid, inspect the vacuum lines connected to the valve for cracks, dry rot, or disconnections. A vacuum leak in the surrounding hoses can mimic a failed solenoid. Additionally, ensure the electrical connector is clean and free of corrosion.
The installation is generally straightforward and can typically be completed in 15 to 30 minutes. You will primarily need basic hand tools, such as a screwdriver or a small socket set, to remove the mounting bracket and disconnect the vacuum hoses and electrical plug. Be sure to note the orientation of the vacuum lines before removal to ensure the new unit is connected correctly.
