A/T Gear Position Switch Short (More Than Two Inputs)

What it means

This is a Honda- and Acura-specific code; the same number can mean something different on other makes. The transmission gear position switch is signaling more than one position at the same time, so the computer cannot tell the real one. It is similar in idea to generic P0705 and can affect shifting and starting.

Models covered: Honda and Acura models with automatic transmission, mainly 1990s–2000s.
