Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting any work.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body opening.
Ensure the throttle plate moves freely and is not sticking.
Reattach the air intake duct securely.

3. Inspect and Replace the Air Filter

Locate the air filter housing and remove the cover.
Take out the old air filter and inspect for dirt or blockages.
Replace with a new air filter if necessary, ensuring a snug fit.
Secure the air filter housing cover.

4. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and check fluid level; add fluid if needed.
If fluid is discolored or has a burnt smell, consider a transmission fluid change.
To change fluid, drain the transmission pan, replace the filter, and refill with manufacturer-recommended fluid.

5. Test the Accelerator Pedal Position Sensor

Locate the sensor and disconnect the wiring harness.
Use a multimeter to check for proper voltage and resistance as you press the accelerator pedal.
Replace the sensor if readings are out of specification.
