Keep the starter locked out until the shifter is in Park or Neutral with the Standard Ignition Neutral Safety Switch NS-674, a Tundra switch built as a direct-fit replacement for the 2007-2019 Toyota Tundra and the 2008-2019 Toyota Sequoia. This electrically operated switch is intended to replace a damaged original unit and help return the vehicle's neutral safety function to normal operation.
The neutral safety switch signals the starting circuit based on the shifter's position, allowing the engine to crank only in Park or Neutral. Signs this part may need replacing include no crank in Park, an engine that starts only in Neutral, or intermittent no-start conditions. Diagnose the starting circuit before replacing, since a weak battery, starter or wiring fault can cause similar symptoms.
Fitment: 2007-2019 Toyota Tundra; 2008-2019 Toyota Sequoia. See the Buyer's Guide tab for engine-specific details.
Interchange: CSW571 · SW8594 · NS7076 · 845400C010
