Standard Ignition AX66 Cabin Air Temperature Sensor

Cabin Temperature Sensor for Chrysler and Dodge

Standard Ignition AX66 is a cabin air temperature sensor built for HVAC temperature monitoring in select Chrysler, Dodge, and Plymouth vehicles. It uses a bolt-on mounting style, an oval female plug-in connector, and a black housing with an included mounting bracket for a direct service replacement.

Key Features

• Cabin air temperature sensor for HVAC systems
• Bolt-on attachment method with mounting bracket included
• Oval female connector with 1 connector and 2 male blade terminals
• Black sensor housing
• Factory-tested for temperature sensor operation
• Built with tight thermistor response tolerances for measurement accuracy

Product Details

Standard Ignition AX66 is engineered for accurate cabin temperature input to the HVAC control system. The sensor design uses controlled thermistor response values to help maintain proper temperature measurement and consistent part operation. Standard Ignition manufactures and tests these sensors in-house, giving technicians a service replacement that matches the electrical and mounting requirements of the original application. This part cross-references Four Seasons 75966 for the same application.

Installation Notes

Verify connector shape, terminal style, and mounting location before installation. AX66 uses a bolt-on design with a plug-in oval connector, so the replacement should match the original sensor interface and bracket position. Inspect the harness connector and HVAC housing for damage before installing the new sensor.
