In the 2006 Cadillac DTS, the throttle position sensor is situated on the side of the throttle body, which is easily found by tracing the air intake hose to the engine. This sensor plays a crucial role in the fuel delivery system as it keeps track of how wide the throttle valve is open, determining the air flow into the engine. Alongside factors like temperature, MAF readings, and engine RPMs, the throttle position sensor helps to establish the ideal air/fuel mixture for efficient combustion. If the sensor malfunctions, it can lead to issues such as the valve staying closed or open, resulting in starting problems or decreased performance. Warning signs that it needs replacement include rough idling, starting difficulties, stalling, and reduced acceleration. The average cost for parts and labor for replacing the sensor ranges from $160 to $220.
