DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input): Description
When the shift lever is in the N or P position: 1) the Park/Neutral Position (PNP) switch turns ON, and 2) ECM terminal NSW is grounded to the body ground via the starter relay and voltage becomes 0V. When the shift lever is in the D, 2, L or R position: 1) the PNP switch turns OFF, and 2) ECM terminal NSW receives current and becomes the voltage of the ECM internal power source.
If the shift lever is moved from the N position to the D position, this signal is used for air-fuel ratio correction and for idle speed control (estimated control).
