Difficulty: Intermediate · About 60 min · Hyundai Elantra

Replace the transmission output-speed sensor on a 2000–2007 Hyundai Elantra, moving the air collector and wheel-well shield to access the sensor.

Steps

1. Remove the air collector

   Remove the air-collector mounting bolts, lift the duct clear, and unplug the output-speed sensor connector. Keep the open intake path free of debris.

2. Raise the vehicle and remove the wheel

   Loosen the wheel nuts, raise and support the vehicle securely, then remove the wheel and hubcap to access the inner splash shield.

3. Remove the wheel-well shield and sensor

   Release the splash-shield bolts and move the panel aside. Remove the sensor retaining bolt and lift the old sensor straight out of its bore.

4. Install the replacement sensor

   Apply a light film of the specified silicone paste to the sensor seal. Seat the new sensor squarely, secure its bolt to specification, and reinstall the splash shield.

5. Reconnect and reassemble

   Refit the wheel and torque its lug nuts to specification in a star pattern. Reconnect the sensor plug, reinstall the air collector, and confirm its duct is secure.

6. Check transmission operation

   Start the vehicle and check for warning lights or stored speed-sensor codes. Verify the speedometer and shifting behavior during a cautious test drive.

Check your vehicle’s repair manual for exact specifications and fit.
