What is the purpose of the Park/Neutral position switch and how can it be checked and adjusted on Toyota 4Runner,Toyota T100 and Toyota Tacoma?

The Neutral Safety Switch prevents the engine from starting in any gear other than Park or Neutral. To check the switch, raise the vehicle and unplug the electrical connector. Test the continuity across the indicated terminals using an ohmmeter. If the switch doesn't operate correctly, try adjusting it and retest. If it still fails, replace it. To adjust the switch, place the Automatic Transmission Shift Levers in Neutral, loosen the retaining bolt, align the groove and neutral basic line, and tighten the bolt. For replacement, follow specific steps for your vehicle model, which may include removing the exhaust pipe and heat shield or detaching oil cooler pipes. Unplug the electrical connector, remove the lock washer and nut, and then remove the retaining bolt to take out the switch. Installation is the reverse of removal, ensuring proper adjustment and continuity testing.

Toyota 4Runner Neutral Safety Switch Parts Questions & Answers

Switch Assy, Neutral Start
84540-30270
Q: What is the purpose of the Park/Neutral position switch and how can it be checked and adjusted on Toyota 4Runner,Toyota T100 and Toyota Tacoma?
A: The Neutral Safety Switch prevents the engine from starting in any gear other than Park or Neutral. To check the switch, raise the vehicle and unplug the electrical connector. Test the continuity across the indicated terminals using an ohmmeter. If the switch doesn't operate correctly, try adjusting it and retest. If it still fails, replace it. To adjust the switch, place the Automatic Transmission Shift Levers in Neutral, loosen the retaining bolt, align the groove and neutral basic line, and tighten the bolt. For replacement, follow specific steps for your vehicle model, which may include removing the exhaust pipe and heat shield or detaching oil cooler pipes. Unplug the electrical connector, remove the lock washer and nut, and then remove the retaining bolt to take out the switch. Installation is the reverse of removal, ensuring proper adjustment and continuity testing.
