Experiencing the Obd2 P0073 error code in your vehicle? This code signals a problem with your car’s ambient air temperature sensor circuit, often leading to inaccurate temperature readings and potentially disabling features like remote start. If you’re noticing your temperature display is incorrect or simply not working, and your check engine light is on with a P0073 code, you might be dealing with a faulty sensor.
The ambient air temperature sensor, crucial for systems that rely on outside temperature readings, is often located in the front of the vehicle, typically in front of the radiator. For models like Chrysler and Dodge vans, including presumably the one mentioned in the original post, this sensor is attached to a vertical support beam near the radiator. Accessing this sensor for replacement often requires removing the front fascia of your vehicle. While it might be tempting to try and reach it by just removing the top radiator support cover, professional service manuals usually recommend front fascia removal to ensure proper access and replacement.
The Original Equipment Manufacturer (OEM) part for the ambient air temperature sensor is Mopar part number 5149265AB. This same sensor is also used in older models like the Dodge Caravan and Chrysler Town & Country (2008+), which can be helpful when sourcing a replacement part.
In conclusion, if you’re facing a P0073 code, suspect a malfunctioning ambient air temperature sensor. Be prepared to remove the front fascia of your vehicle to access and replace it. Using the correct Mopar part number 5149265AB will ensure compatibility and restore proper temperature readings and functionality to your vehicle’s systems.
