In a 2006 Lexus GS300, the camshaft position sensor is typically located beneath the AC compressor on the engine block. Its role is to track the camshaft's position as it rotates. This data is then relayed to the Engine Control Unit (ECU), enabling it to make precise adjustments for air, fuel, and spark timing to ensure proper combustion in the cylinder. If this sensor malfunctions, you may experience a rough-running engine with inefficient combustion. A common indicator of a failing sensor is the illumination of the check engine light on your dashboard. To diagnose the issue, you can utilize an OBD II scan tool to retrieve error codes and pinpoint the problem with the sensor.
