Code P1717 Acura Description

The P1717 Acura code indicates a Transmission Range Switch Circuit Open, which means that there is an issue with the transmission range switch circuit being open when it should be closed. The transmission range switch, also known as the neutral safety switch, is responsible for indicating the gear position of the transmission to the engine control module (ECM). This information is crucial for the ECM to adjust various parameters such as fuel delivery, ignition timing, and shift points. When the circuit is open, the ECM cannot accurately determine the gear position, leading to performance issues and potential safety concerns. If left unaddressed, this issue can result in erratic shifting, poor fuel economy, and even transmission damage.

  • I just had my diagnostic done at Autozone. I will check with my service provider on the cost of replacing the transmission range sensor. As to how the car is riding, I am experiencing a subtle kind of dragging when I'm in automatic but not when I'm in manual/sport mode.
