Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Transmission Fluid

Remove the transmission fluid dipstick and check the fluid level.
If the fluid is low or dirty, drain the old fluid using a drain pan.
Replace with the manufacturer's recommended transmission fluid.
Reinsert the dipstick and ensure it is properly seated.

3. Clean or Replace Throttle Body

Remove the air intake hose from the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
If damaged, replace the throttle body with a new unit, ensuring all gaskets are replaced.
Reattach the air intake hose securely.

4. Test and Replace Accelerator Pedal Position Sensor

Locate the accelerator pedal position sensor under the dashboard.
Disconnect the electrical connector and test the sensor using a multimeter for resistance values specified in the service manual.
If out of specification, replace the sensor with a new one and reconnect.

5. Fuel System Check

Use a fuel pressure gauge to check the fuel pump pressure at the fuel rail.
If pressure is low, inspect and replace the fuel filter or fuel pump as necessary.
Ensure all fuel lines are secure and not leaking.
