Airtex 1S7413 Neutral Safety Switch Transmission Range Sensor

The Airtex 1S7413 is a direct-fit replacement neutral safety switch, also known as a transmission range sensor or inhibitor switch, designed to restore proper starting and backup lamp operation on compatible automatic transmission vehicles.

The neutral safety switch is a critical safety component that prevents the engine from starting unless the transmission is in Park or Neutral. It also controls the backup (reverse) lights and, on many applications, communicates gear position to the vehicle's powertrain control module (PCM).

• Direct OEM replacement — matches original fit, form, and function
• Prevents engine start in any gear other than Park or Neutral
• Controls backup lamp circuit activation in Reverse
