Code C0165 Saturn Description

The C0165 diagnostic trouble code (DTC) for Saturn vehicles indicates a problem with the Antilock Brake System (ABS) and Traction Control System (TCS) Brake Switch/Sensor Circuit being open. This means that there is an issue with the circuit that controls the brake switch or sensor, which is crucial for the proper functioning of the ABS and TCS systems. The ABS system prevents the wheels from locking up during braking, improving vehicle control and stability, while the TCS system helps prevent wheel spin during acceleration on slippery surfaces.
