How to Remove Ambient Air Temp Sensor 06-12 Nissan Altima

Difficulty: Intermediate · About 45 min · Nissan Altima

Replace the ambient temperature sensor on a Nissan Altima by carefully removing the bumper cover and restoring all clips and fasteners.

Steps

1. Remove the front bumper cover

   Release the upper push pins, wheel-well fasteners, and lower splash-shield screws. Free the cover edges from the fenders, then lift the cover away without forcing its tabs.

2. Release the sensor

   Disconnect the sensor electrical plug and unclip its holder from the bumper support. Inspect the connector for damage before removing the sensor assembly.

3. Fit and connect the sensor

   Clip the replacement sensor into its original holder and reconnect the harness until its lock engages. Route the wire clear of sharp edges and moving components.

4. Reinstall the bumper cover

   Align the cover tabs at both fenders and press them into place. Refit the lower screws, splash-shield clips, wheel-well bolts, and upper retainers, then check the outside temperature display.

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