Detailed Description

Standard Ignition AX266 is an ambient air temperature sensor used by the HVAC system to read outside air temperature and send that information to the vehicle’s climate controls. On Volvo S40 and Volvo V40 models from 2000 through 2004, this sensor supports accurate temperature reporting for automatic climate functions and dashboard temperature display logic. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Use AX266 when servicing a failed ambient temperature sensor on a Volvo S40 or Volvo V40. The plug-in female connector, 2 blade terminals, and push-on attachment method make it a direct-fit style replacement for the listed vehicles. Standard Ignition AX266 is also referenced by interchange numbers 308103750, SU13312, TS57393, and WT5702.

What It Helps Fix

• Incorrect outside air temperature readings
• HVAC display showing implausible ambient temperature values
• Climate control behavior affected by a faulty temperature input
• Temperature sensor warning or sensor-related HVAC faults
• Loss of accurate ambient air data on Volvo S40 and V40 models

Installation Notes and Tips

Verify connector style, terminal layout, and mounting location before installation. Compare the original sensor to Standard Ignition AX266 to confirm the push-on attachment and plug-in female connector match the vehicle harness. For best results, inspect the connector for corrosion or damaged terminals before installing the replacement sensor.

Quality Assurance

Standard Ignition supplies replacement electrical and HVAC components for service applications, and AX266 is built to match the listed fitment for 2000-2004 Volvo S40 and 2000-2004 Volvo V40.
