Dirty Throttle Body
A dirty throttle body often causes the Acura Code P2176. The throttle body is the component responsible for controlling the air flow entering the engine. When the throttle body gets dirty, the airflow is obstructed, and your engine may be unable to idle properly. You need to clean the throttle body with a suitable cleaner to resolve this issue.
Poor Connections or Loose Terminals at the Throttle Body and PCM
If the terminals at the throttle body and the PCM are loose or not connected properly, this can also cause the Acura Code P2176. To resolve this issue, you need to replace or reconnect the terminals.
“Open” Circuit between the Throttle Body and PCM
An “open” circuit between the throttle body and the PCM can also trigger the Acura Code P2176. To resolve this issue, you must check the throttle body wiring and ensure all the connections are properly connected and secure.
Faulty Throttle Body
If the throttle body is faulty, this can also be the source of the Acura Code P2176. You need to replace the throttle body with a new one to resolve this issue.
