Product Overview
WAI engineers this starter to meet the electrical demands of today’s vehicles with a new-unit construction rather than remanufactured components. The 17806N is built around DENSO-style fitment and the specified 12V, 1.0 kW configuration, making it a practical replacement for Toyota Echo and Toyota Yaris models that use the listed starter setup. This part cross-references BBB Industries 17805 and Quality-Built 17806 for the same application.
Common Starting Issues It Can Address
- Slow or weak engine cranking
- No-crank condition when the battery and cables test good
- Intermittent starter engagement
- Grinding or inconsistent starter drive operation

Installation Notes and Tips
Verify the vehicle’s original starter specifications before installation, including 12V system voltage, clockwise rotation, 9-tooth drive count, flange mount, and DENSO family match. Confirm the application notes for 2003-2005 Toyota Echo and 2012 Toyota Yaris, since those listings reference Denso 0.8 kW units supplied as Denso 1.0 kW replacements. Inspect battery condition, cable integrity, and charging-system output during replacement to help avoid repeat starting complaints.
