The P2072 trouble code indicates indicates an issue with the throttle actuator control system due to ice blockage.
P2072 Throttle Actuator Control System – Ice Blockage
Code symptoms P2072.
1. Reduced engine power or lack of throttle response.
2. Engine stalling or hesitation during acceleration.
3. Check Engine Light (CEL) or Malfunction Indicator Lamp (MIL) illumination.
4. Rough idling or fluctuating idle speed.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.

1. Accumulation of ice or frost around the throttle actuator assembly, typically in cold weather conditions.
2. Moisture ingress into the throttle actuator assembly leading to ice formation.
3. Malfunctioning throttle actuator motor or position sensor.
4. Wiring harness or connector issues affecting the throttle actuator control circuit.
Code Solutions P2072.
1. Thoroughly inspect the throttle actuator assembly for any signs of ice or frost buildup. Clear any ice blockage using a suitable de-icing agent or warm air.
2. Ensure proper sealing and insulation around the throttle actuator to prevent moisture ingress. Replace any damaged seals or gaskets.
3. Test the throttle actuator motor and position sensor for proper operation. Replace faulty components as necessary.
4. Check the wiring harness and connectors associated with the throttle actuator control circuit for any damage or corrosion. Repair or replace damaged components.
