Code P0705 Saturn Description

The P0705 diagnostic trouble code (DTC) for Saturn vehicles indicates a Transmission Range Sensor Circuit Malfunction. This means that there is an issue with the transmission range sensor, also known as the neutral safety switch. The transmission range sensor is responsible for detecting the gear position of the vehicle and sending this information to the engine control module (ECM). If the ECM detects a malfunction in the transmission range sensor circuit, it can cause a variety of problems with the vehicle's transmission and overall performance.
