What It Helps Address

• Incorrect cabin temperature readings
• HVAC systems that cycle air improperly
• Climate control performance issues tied to sensor input
• Fault codes related to interior temperature sensing
• Uneven or unstable cabin temperature regulation

Installation Notes and Tips

Verify connector shape, terminal style, and mounting location before installation. This sensor uses a single square female connector with two male pin terminals, and it does not include a mounting bracket or wiring harness. Confirm the vehicle’s original sensor configuration matches the AX527 before replacement.
