Detailed Description

Standard Ignition AX143 is built for vehicles that rely on an in-cabin temperature signal to help the HVAC control system regulate blower output and air delivery. This cabin air temperature sensor uses a single rectangular female connector, male blade terminals, and a bolt-on mounting style to match the original service layout on supported vehicles. It is listed for 2004-2008 Acura TL and 2003-2005 Honda Civic applications, making it a focused replacement for common climate-control repairs on these platforms. The AX143 part number is also useful when cross-referencing OE-style replacements for the same application.

What It Helps Address

• Incorrect cabin temperature readings sent to the HVAC control system
• Unstable or inconsistent automatic climate control behavior
• HVAC systems that do not respond properly to interior temperature changes
• Fault codes related to cabin temperature sensor performance
• Poor temperature regulation in Acura TL and Honda Civic HVAC systems

Installation Notes and Tips

Verify connector shape, terminal style, and mounting location before installation. This sensor uses a plug-in rectangular connector and bolt-on attachment method, so the original sensor location and electrical connection should be inspected for corrosion, damage, or looseness before fitting the replacement.
