Transmission Range Sensor (Shift Switch) Inspection and Adjustment
Inspection
1. Disconnect transmission range sensor connector (1).
2. Check that continuity exists at terminals shown in the following figure by moving selector lever.
Adjustment
1. Shift manual shift lever (1) to "N" range.
2. Connect ohmmeter between 7 and 9 terminals of disconnected transmission range sensor connector (3).
3. Turn transmission range sensor (2) gradually to find position where ohmmeter reading indicates continuity. Then fix transmission range sensor (2) at that position by tightening bolts to specified torque.
Tightening torque
Transmission range sensor bolts (a): 25 Nm (2.5 kgf-cm, 18.0 ft. lbs.)
4. Connect transmission range sensor connector (3).
5. Check that engine starts in "N" and "P" ranges but it doesn't start in "D", "2", "L" or "R" range. Also, check that back-up lamp turn ON in "R" range.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
