Standard Ignition Neutral Safety Switch P/N:NS-644
Standard Motor Products
Standard Ignition NS-158 neutral safety switch for the 1998-2004 Honda Odyssey and other vehicles is an electrically operated switch that restores the neutral safety function. It is a direct-fit replacement for damaged OE units.
If the switch has failed, the engine may not crank in Park or Neutral, or it may crank while the transmission is in gear. A weak battery, a faulty starter relay or worn shift linkage can be behind those signs too, so find the cause before buying. The vehicle takes one switch.
It fits the 1998-2004 Honda Odyssey and the 2003-2004 Honda Pilot, and it is a neutral safety switch for the 1998-2002 Honda Accord and other Honda and Acura models. It is made to OE spec for fit, form and function. If your car is not named here, look for it in the Vehicles it fits section.
