Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during inspection and repair.

2. Inspect and Clean the MAF Sensor

Locate the MAF sensor, which is typically found between the air filter and the throttle body.
Remove the electrical connector from the MAF sensor.
Use a MAF sensor cleaner to spray the sensor element. Allow to dry completely before reinstallation.

3. Fuel System Inspection

Locate the fuel pump access panel (if applicable) or lift the vehicle to access the fuel tank.
Check the fuel pump operation by turning the ignition key to the ON position (not starting) and listening for the pump's activation sound.
If necessary, replace the fuel filter and inspect the fuel lines for leaks or blockages.

4. Throttle Position Sensor Testing

Locate the TPS on the throttle body.
Disconnect the electrical connector.
Using a multimeter, measure the resistance across the sensor terminals while slowly opening and closing the throttle. Look for a smooth, linear response.
If the TPS is faulty, replace it with a new unit.

5. Reassemble and Reconnect

Reinstall all components and connectors that were removed for inspection.
Reconnect the battery and ensure all electrical connections are secure.
