Throttle Body: A component that controls the amount of air entering the engine.
Bank 2: The side of the engine opposite bank 1, typically in V-type engines.
• P0101
• P0171
This means that there's a problem with the air going into the engine on one side. It's like if you were trying to breathe through a straw that was bent or blocked.
The engine control module (ECM) has detected an issue with the air supply to the throttle control system on bank 2 of the engine.
The P1455 code indicates that the throttle control system is receiving an incorrect amount of air supply on bank 2. This can affect the engine's performance and efficiency, as it relies on a precise air-fuel mixture for optimal operation.
