Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
  • Allow the engine to cool if it has been running.
2. Clean the Throttle Body
  • Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
  • Remove the intake duct connected to the throttle body.
  • Spray throttle body cleaner onto a soft cloth and wipe the interior of the throttle body, ensuring to remove carbon deposits.
  • Open the throttle plate manually to clean the backside.
  • Reattach the intake duct securely.
3. Replace the Air Filter (if necessary)
  • Tools Required: Screwdriver set or socket set (depending on air filter housing).
  • Locate the air filter housing and remove the cover.
  • Take out the old air filter and inspect for dirt and blockages.
  • Install a new air filter, ensuring it fits snugly in place.
  • Secure the housing cover back on.
4. Test and Replace the Throttle Position Sensor (if necessary)
  • Tools Required: Multimeter, socket set.
  • Disconnect the electrical connector from the throttle position sensor.
  • Use a multimeter to measure the voltage output of the TPS while moving the throttle.
  • If readings are outside the specified range (refer to your service manual), replace the TPS.
  • Reconnect the electrical connector and ensure it is secure.
