The P0073 diagnostic trouble code (DTC) for Volkswagen vehicles refers to the Ambient Air Temperature Sensor Circuit High Input. This code indicates that the ambient air temperature sensor is providing a higher than expected signal to the engine control module (ECM).

2022年9月26日 · Here’s the definition of P0073 for the Volkswagen Transporter broken down into its two main parts: 1. Ambient Air Temperature (AAT) Sensor. The AAT sensor measures the air temperature outside of the van’s cabin. It converts this signal to a voltage value the Powertrain Control Module (PCM) can read.

2021年7月23日 · DTC P0073 stands for “Ambient Air Temperature Circuit High.” The code is logged once there’s a possible issue with your AAT sensor. Your vehicle’s ambient air temperature sensor measures the temperature of the outside air. Code P0073 usually won’t cause any drivability issues.

2024年5月10日 · The P0073 trouble code specifically denotes an issue with the Ambient Air Temperature sensor circuit’s high input. It indicates that the voltage signal received from the AAT sensor exceeds the expected threshold, deviating from predetermined parameters.
