This part replaces multiple OEM numbers including 5019881AA, 4796563, and 5174039AA.

Each sensor is designed and tested to match original specifications, using premium materials and high-quality pin terminals for longer life. Installation is pretty straightforward if you're handy, but as with any AC work, you'll need to properly evacuate and recharge the system. The build quality feels solid and reliable.
