• Brass sensor material with plastic housing construction
• Rectangular female connector with pin terminal design
• Clip-on mounting style for OE-style placement
• Wiring harness not included
• Operating range: -40 to 257 degrees
• Length: 1.77 in.

OE-Style Temperature Signal Replacement

This ambient air temperature sensor is engineered for direct replacement use on vehicles that rely on an accurate outside temperature reading for HVAC control and instrument cluster display. The Dorman 902-029 is a practical replacement for Chrysler 300, Dodge Charger, Jeep Grand Cherokee, and other listed applications where the original sensor has failed or drifted out of range. This part cross-references Gates AX75 and HOLSTEIN 2ACT0138 for the same application.

What This Sensor Helps Address

• Incorrect outside temperature readings on the dash
• Blank, erratic, or delayed ambient temperature display
• HVAC behavior affected by a faulty ambient air sensor signal
• Sensor damage from age, road debris, or weather exposure
• Connector or terminal wear at the original sensor location

Installation Notes

Verify connector shape, terminal type, and mounting style before installation. The Dorman 902-029 uses a female rectangular connector with a single terminal and clip-on mounting, so the original sensor location and harness condition should be checked before replacement. Confirm the vehicle application against the fitment list for Chrysler, Dodge, Jeep, and Ram models before ordering.
