Скачать или смотреть How To Fix P0073 Code - Ambient Air Temperature Sensor Circuit High - How To Test And Fix

If you are seeing code P0073 on your scanner and your car's outside temperature display is reading incorrectly, this video walks you through the diagnosis and repair process effectively. This trouble code indicates a high input in the ambient air temperature sensor circuit, which often causes your air conditioning to stop blowing cold air because the system thinks it is freezing outside. I explain exactly where to find the AAT sensor, which is usually located in front of the radiator, and how to inspect the wiring connector for common issues like corrosion or melted plastic. You will learn how to use a multimeter to measure resistance across the sensor pins to determine if the sensor itself is dead. I also cover testing the wiring harness with a jumper wire to rule out a broken circuit leading back to the PCM. Whether you are driving a Ford, BMW, or Chrysler, follow these steps to fix the electrical fault and get your AC working again.
