How to Remove Ambient Temp Sensor 03-07 Honda Accord

Difficulty: Intermediate · About 50 min · Honda Accord

Replace the ambient air temperature sensor on a 2003–2007 Honda Accord after removing the front bumper cover for access to its mounting bracket.

Steps

1. Remove the bumper cover

   Protect the bumper edges with masking tape and remove the upper and lower shrouds by releasing their plastic retainers. Remove the corner screws and grille fasteners, release the clips below the headlights, and pull the cover forward carefully.

2. Disconnect the old sensor

   Support the cover so it does not hang by any wiring. Release the sensor from its bracket and unplug its connector by pressing the locking tab.

3. Install the replacement sensor

   Reconnect the new sensor and slide it onto the bracket until its retainer locks. Route the harness along its original path and keep it clear of moving or hot components.

4. Reinstall the bumper cover

   Align the upper tabs first, then engage the side and headlamp clips. Reinstall the corner fasteners and both shrouds with their retainers, checking for even gaps.

5. Verify the reading

   Switch on the vehicle and confirm the outside-temperature display responds after it updates. Recheck the bumper clips and sensor wiring before driving.

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