Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.

Tools Required:

OBD-II scanner
Socket set
Screwdriver set
Multimeter

2. Inspect and Repair Throttle Cable

Sub-steps:
1. Locate the throttle cable connected to the gas pedal and throttle body.
2. Inspect the cable for fraying or disconnection.
3. If damaged, replace with a new throttle cable.
4. Adjust the cable tension as specified in the vehicle's service manual.

3. Check Accelerator Pedal Assembly

Sub-steps:
1. Remove any covers to access the accelerator pedal assembly.
2. Inspect the pivot points and linkage for obstructions or damage.
3. Lubricate moving parts if necessary, or replace the assembly if faulty.

4. Test and Replace Throttle Position Sensor

Sub-steps:
1. Disconnect the electrical connector from the TPS.
2. Use a multimeter to measure the resistance across the sensor terminals.
3. Compare readings to specifications in the service manual.
4. If out of specification, remove the old TPS and install a new one.

5. Inspect and Clean Electronic Throttle Body (if equipped)

Sub-steps:
1. Remove the electronic throttle body from the intake manifold.
2. Clean the throttle plate and bore using throttle body cleaner.
3. Reinstall the throttle body and reconnect electrical connections.
