2003 Toyota Sequoia Parts Questions & Experts Answers

• Q: How to service and repair the Neutral Safety Switch on 2003 Toyota Sequoia?

  A: The transmission oil cooler pipe needs to be disconnected at the beginning of any repair work on the Transmission Position Switch/Sensor. Unplugging the connector is the first step before prying loose the lock washer and progressively taking out the switch and its nut and bolt one after another. The service requires a new Park/Neutral Position Switch and bolt installation following a torque of 13 Nm (130 kgf-cm, 9 ft. lbs.) then the application of a new lock plate and nut with proper 3.9 Nm (40 kgf-cm, 35 inch lbs.) torque and claw bending on the lock plate to maintain nut security. Check the engine operation through the connector by ensuring it starts only during N or P shift lever positions; redo the adjustment if needed. The maintenance continues with pipeline reattachment followed by ATF filling then checking the fluid level and executing a test drive of the vehicle.
