What does P0073 code mean?
Ambient Air Temperature Sensor Circuit High input
P0073 is a diagnostic trouble code (DTC) for “Ambient Air Temperature Sensor Circuit High input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
When to set the ambient air temperature code p0073?
Code P0073 may be set if the PCM perceives a problem with your vehicle’s ambient air temperature (AAT) sensor or the sensor’s circuit. To function properly, the CCM relies on various sensors that keep track of various factors that affect cabin climate.
What does DTC code p0073 stand for?
Diagnostic trouble code (DTC) P0073 stands for “Ambient Air Temperature Sensor Circuit High.” It indicates that there might be a problem with your vehicle’s ambient air temperature (AAT) sensor or the sensor’s circuit. Automatic climate control systems have made it easier for users to select the right temperature for their vehicle’s cabin.
What causes the p0073 trouble code to be stored in the PCM?
There are several things that could cause the P0073 trouble code to be stored by the Power Control Module (PCM): The ambient air temperature sensor has malfunctioned The wiring has shorted or broken There is corrosion in the electric circuitry or connector A break or short in the ambient air temperature harness Debris that is covering the sensor
What causes a p0073 problem on an AAT sensor?
Potential causes of a P0073 trouble code may include: Short to voltage in the signal circuit to the AAT sensor A good starting point is always to check for technical service bulletins (TSB) for your particular vehicle. Your issue may be a known issue with a known fix put out by the manufacturer and can save you time and money during diagnosis.
