Lexus ES350 Neutral Safety Switch

Lexus ES350 Neutral Safety Switch is designed to ensure that the sedan only cranks when the car's transmission lever is in the park or neutral position, an easy to implement measure to prevent any unexpected movement when the driver turns the key or pushes the start button. This Neutral Safety Switch is like an electric gatekeeper, standing in the starter circuit waiting to close the pathway for current to flow to the starter motor until the shift selector is in a safe position. Early Lexus ES350 editions had a simple spring-loaded contact connected directly to the shifter, while later ES350 versions had a sealed sensor that passed position information to the powertrain control module, but either type serves the same function which prohibits starts in the drive or reverse positions. The new approach, which is now applied in many Lexus assemblies, is more durable and faster to communicate electronically, while the older style of contact in first ES350 years is more susceptible to wear or moisture. Regardless of generation, the Neutral Safety Switch is one of the important lines of defense, protecting the engine, transmission, and other traffic around the vehicle from hazards caused by an unintentional launch. Should the Neutral Safety Switch stick, misread gear position, or allow intermittent cranking, drivers will immediately know the inconvenience but the underlying risk is even greater. Prompt attention to a malfunctioning Neutral Safety Switch keeps every Lexus rolling off safely.
