Details of the Dodge p0073 OBD Code
Dodge fault code P0073 relates to ambient air temperature sensor high input.
Dodge OBD code P0073 means Ambient Air Temperature Sensor Circuit High.
This code is triggered by the Engine Control Module (ECM) when it detects a high voltage signal from the ambient air temperature sensor.
The ambient air temperature sensor is responsible for providing the ECM with information about the temperature of the air entering the engine.
When the sensor sends a signal that is higher than expected, the ECM sets code P0073 to indicate a circuit high condition.
Mechanic’s Tech Notes
Detailed information on Dodge fault code P0073, which relates to ambient air temperature sensor circuit high input.
To diagnose and fix OBDII code P0073 on a Dodge, start by checking the power and ground to the Transmission Control Module (TCM) using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) network with a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of corrosion, bending, or breakage.
This thorough inspection can help identify and resolve issues related to the TCM and its circuitry.
