Detailed Description

Standard Ignition AX231 is an ambient air temperature sensor used to report outside air temperature data to the vehicle’s HVAC and related control systems. For INFINITI G37 models from 2008 through 2013, this sensor supports accurate temperature feedback so the system can display ambient conditions and manage climate-control logic. The AX231 is a direct-fit style replacement with a female connector, two male blade terminals, and a plug-in connection layout.

This part cross-references Nissan OE number 27710JL00A for the same application. If you are replacing a failed ambient temperature sensor on an INFINITI G37, AX231 provides the correct connector style and mounting approach for service work on the original location.

Common Problems This Part May Solve

• Incorrect outside temperature readings on the dash display
• HVAC temperature feedback errors
• Intermittent ambient air sensor signal loss
• Faulty sensor response after impact or road debris exposure
• Replacement need after connector or terminal wear

Installation Notes and Tips

Verify connector shape, terminal style, and mounting style before installation. The sensor uses a push-on attachment method and does not include a wiring harness or mounting bracket, so reuse the original vehicle hardware and connector routing where applicable. Confirm the replacement location on the vehicle before service and inspect the connector for corrosion or damaged terminals.

Quality Assurance

Standard Ignition supplies replacement electrical and sensor components for service applications, and AX231 is listed with OE cross-reference support for the same vehicle use case. Confirm fitment against the vehicle’s year, make, and model before ordering.
