DTC P0705: Transaxle Range Switch Circuit: Description

Transaxle range switch determines which gear position has been manually selected. PCM determines this gear selection by detecting a combination of opens and grounds at 4 switch inputs of transaxle range switch. When a switch is open, PCM code input will be high (near ignition voltage). When switch is closed, PCM code input will be low (zero volts). Specific combination of highs and lows (opens and grounds at switch) for 4 code inputs at PCM denote which gear position has been selected. Only one combination is possible for each manual gear selected. DTC sets when PCM code input combination is not valid.
