Detailed Description

Standard Ignition AX344 is built for vehicles that use a bumper-mounted ambient air temperature sensor to monitor outside temperature. This sensor supports HVAC system logic and temperature display functions by sending ambient air data to the vehicle control system. It is a direct-fit style replacement for select Honda and Acura applications, including Honda Accord, Civic, Odyssey, Fit, Crosstour, HR-V, Pilot, and Acura MDX, RLX, TLX, RDX, and ILX. This part cross-references Dorman OE Solutions 902-037 for the same application.

Use AX344 when replacing a damaged or inaccurate outside temperature sensor on a Honda Civic, Honda Accord, or Acura MDX equipped with the matching bumper-mounted connector style. The Standard Ignition AX344 part number is also referenced in interchange listings for service lookup and catalog matching.

Common Issues This Sensor Can Address

• Incorrect outside air temperature readings on the dash display
• HVAC behavior affected by a failed ambient temperature input
• Temperature readings that fluctuate after sensor damage at the bumper
• Diagnostic trouble related to ambient air temperature signal loss
• Broken connector or corrosion at the original sensor location

Installation Notes and Tips

Install at the bumper-mounted sensor location and verify the connector style before replacement. Inspect the harness connector, terminals, and surrounding mounting area for damage or corrosion before plugging in the new sensor. Confirm fitment by year, make, and model for the exact application, especially on Honda HR-V, Honda Pilot, and Acura TLX vehicles.
