Ambient Air Temperature Sensor for Hyundai Sonata

Standard Ignition AX653 is an ambient air temperature sensor for select Hyundai Sonata applications. It uses a 2-terminal, plug-in oval connector with a female connector and male blade terminals, plus a bolt-on mounting style and included bracket for a secure fit in the grille area on the 2017 Sonata and in 2018-2019 Sonata applications.

Key Features

  • Ambient air temperature sensor for HVAC-related temperature input
  • Fits 2018-2019 Hyundai Sonata and 2017 Hyundai Sonata, in grille
  • Standard Ignition AX653 replacement part number
  • 2-terminal design with one oval plug-in connector

Detailed Description

Standard Ignition AX653 is built for vehicles that rely on an exterior ambient temperature reading to support climate control display and HVAC system operation. This ambient air temperature sensor uses a single oval connector, one port, and a bolt-on mounting design to match the original-style installation on the Hyundai Sonata. It is a direct-fit option for 2018-2019 Hyundai Sonata models and 2017 Hyundai Sonata models with grille-mounted placement. This part number, AX653, is also a useful reference when cross-checking replacement needs against OE-style listings.

This part cross-references 97280C2AA0 and ATSA546 for the same application.

What It Helps Resolve

  • Incorrect outside temperature display on the dash
  • Temperature readings that fluctuate or read inconsistently
  • HVAC control issues tied to ambient air input
  • Sensor damage from grille-area exposure
  • Replacement needs after connector or terminal wear

Installation Notes and Tips

Verify the connector shape, terminal count, and grille-mounted location before installation. Standard Ignition AX653 uses a plug-in oval connector with male blade terminals and a bolt-on mounting style, so the replacement should match the vehicle’s original sensor interface. Confirm fitment for your Hyundai Sonata by year and position before ordering.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and sensor components. AX653 is built to meet the application requirements for the listed Hyundai Sonata fitments and to support consistent ambient temperature signal input.
