• Tools Required: Multimeter, socket set.
• Steps:
  1. Locate the throttle position sensor on the throttle body.
  2. Disconnect the electrical connector.
  3. Use a multimeter to check the sensor's resistance according to the service manual specifications.

4. Test and Replace Fuel Pump (if necessary)

• Tools Required: Fuel pressure gauge, socket set.
• Steps:
  1. Locate the fuel pump access point (usually under the rear seat or trunk).
  2. Connect the fuel pressure gauge to the fuel line.
  3. Turn the ignition on without starting the engine and check the pressure reading.
  4. If the pressure is below specifications, replace the fuel pump.
  5. Reassemble the fuel pump assembly and reconnect the battery.
