P1706 · HondaTCM A/T Gear Position Switch Circuit Open

P1706 on Honda vehicles means the transmission control module (TCM) has detected an open circuit in the automatic transmission (A/T) gear position switch circuit. The TCM monitors the switch's signal and sees no valid voltage return, so it cannot confirm which gear the shifter is in and sets this code.
