Ambient Air Temperature Sensor for Subaru HVAC

Standard Ignition AX212 is an ambient air temperature sensor for Subaru HVAC systems. It provides the temperature input used by the climate control system to monitor outside air conditions on select Subaru Forester and Subaru Impreza applications.

Key Features

• Ambient air temperature sensor for HVAC temperature monitoring
• Standard Ignition AX212 replacement part number
• 2-terminal design with female connector and male blade terminals
• Plug-in connector with round and rectangular connector shapes
• Black finish with push-on attachment method
• Sensor only; wiring harness not included
• No mounting bracket included

Detailed Description

The Standard Ignition AX212 ambient air temperature sensor is built for Subaru climate control systems that rely on accurate outside temperature input. It uses a 2-terminal, blade-style connection with a female connector and plug-in design for direct replacement service. This part number is commonly searched as AX212 for Subaru Forester and Subaru Impreza HVAC repairs, including 2003-2015 Subaru Forester and 2008-2015 Subaru Impreza applications. This part cross-references SU13299 for the same application.

Use AX212 when the HVAC system needs a replacement ambient temperature sensor that matches the original connector style and mounting interface. The sensor is supplied in black finish and includes the sensor only, which keeps the replacement focused on the failed component.

Common Issues This Part Can Address

• Incorrect outside temperature display
• HVAC system reading ambient temperature inaccurately
• Climate control behavior affected by a failed temperature sensor
• Intermittent temperature signal to the HVAC module
• Replacement need after sensor damage or connector wear

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. AX212 uses a plug-in connection with 2 terminals and no wiring harness, so the existing vehicle harness must be in serviceable condition. Confirm fitment for your Subaru Forester or Subaru Impreza by year before ordering, including 2002 Subaru Forester from 2/1/02.

Quality Assurance

Standard Ignition supplies replacement electrical and HVAC components for service applications, and AX212 is built to match the listed connector and terminal configuration for the confirmed Subaru fitments.
