WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tundra, 2002 Toyota Tacoma, 2002 Toyota Sienna, 2002 Toyota Sequoia, and 2002 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
  1. Using NEW lock plate, install PNP switch on transaxle. Install and tighten PNP switch retaining nut and PNP switch retaining bolts to specification. See TORQUE SPECIFICATIONS . Bend over tab on lock plate against PNP switching retaining nut.
  2. Reinstall control lever, washer and nut on PNP switch. Tighten nut for control lever to specification. See TORQUE SPECIFICATIONS . Reconnect shift cable on control lever. Check that engine starts only with shift lever in Park and Neutral. If PNP switch adjustment is required, go to next step.
  3. Ensure parking brake is applied. Place shift lever in Neutral. Loosen PNP switch retaining bolts.
  4. Rotate PNP switch so neutral base line aligns with the groove. See Fig 2 and Fig 3 . Tighten PNP switch retaining bolts to specification. See TORQUE SPECIFICATIONS .
  5. Ensure continuity exists between specified terminals on PNP switch in relation to shift lever position. See PARK/NEUTRAL POSITION SWITCH under ENGINE SENSORS & SWITCHES in SYSTEM & COMPONENT TESTING - V6 & V8 article. Reinstall electrical connector.
