How to check and replace the Neutral Safety Switch on the Ford Crown Victoria?

For 1988 through 1991 models and 1992 models with AOD transmission, to check the operation of the neutral start switch, apply the parking brake and attempt to start the engine in each position of the selector lever; the engine should only start in Park and Neutral. If it starts in any other position, adjust the shift linkage and retest. If the engine still starts in any position other than Park or Neutral, replace the switch. To replace the switch, disconnect the cable from the negative battery terminal, place the shift lever in Low, and apply the parking brake. Raise the vehicle and secure it on jackstands, then unplug the electrical connector from the neutral start switch. Carefully remove the switch and O-ring, install the new switch and O-ring, and tighten it. Reinstall the electrical connector and reconnect the negative battery cable. Verify that the engine starts only when in Park or Neutral. For 1992 models with AODE transmission and all 1993 and later models, note that the AODE and 4R70W transmissions do not have a neutral switch; this function is incorporated into an information sensor known as the Manual Lever Position (MLP) sensor or, for 1995 and later models, the Transmission Range (TR) sensor. For adjustment details, consult the relevant information.

Ford Crown Victoria Neutral Safety Switch

The Ford Crown Victoria Neutral Safety Switch makes sure that the engine will only start when the ignition circuit makes contact. This only occurs when the transmission lever is placed into park or neutral. Thus, it won't allow the engine to crank if the car is in drive or reverse. The Neutral Safety Switch acts as an electrical gate that is mounted on the shift linkage. Once the shifter is in position (for example, in park or neutral), it sends the go signal to the starter relay. While the shifter mechanism is in gear, it will prevent that power from going to the starter relay. After the feature was introduced, all Crown Victorias built after the feature arrived use the same simple park neutral inhibition strategy. As such, the driver experiences a predictable mix of behavior, regardless of trim. Ford's only modifications to the Neutral Safety Switch were plug shapes and bracket locations, all to accommodate wire changes with each year's model. In actuality, the core design is the same from year to year, which drivers have confirmed on drivers' own. As a result, compatibility cross year is common, barring a little check of the pins. The Crown Victoria police interceptor versions also have this protection, using the same Neutral Safety Switch logic. With its mechanical simplicity, Ford makes sure the usually no start condition caused by a failed Neutral Safety Switch is a sought-after quality by Ford owners of the Crown Victoria.
