- Locate the transmission linkage and visually inspect for damage or disconnection.
- Adjust the linkage as necessary to ensure proper engagement of the transmission.
- Tighten any loose bolts and ensure the linkage moves freely without obstruction.
Tools Required:
- Wrench set
- Screwdrivers

4. Replace Throttle Position Sensor (if faulty)

Sub-steps:
- Disconnect the electrical connector from the TPS.
- Remove the mounting screws and take out the faulty sensor.
- Install the new TPS and secure it with screws.
- Reconnect the electrical connector and ensure a snug fit.
Parts Required:
- Throttle Position Sensor

5. Reconnect Battery and Test

Sub-steps:
- Reconnect the battery terminals.
