1. Cam Sensor: The cam sensor itself is a relatively inexpensive part, typically costing between $50 to $100. However, the cost may vary depending on the brand and quality of the sensor you choose.
2. Labor: Replacing a cam sensor usually involves removing and replacing some engine components, such as the valve cover. The labor time required for this repair can vary, but it generally takes around 1-2 hours. The labor cost will depend on the hourly rate charged by the repair shop and can range from $50 to $200.
3. Additional Costs: In some cases, additional parts or services may be required, such as engine gaskets or fluids. These additional costs can vary but typically fall within the range of $20 to $50.
So, taking these factors into account, the total cost to fix a cam sensor on a 1999 Buick Century can range approximately between $120 and $350, including both parts and labor. However, it's essential to get a specific estimate from a qualified repair shop, as prices can vary based on your location and the specific circumstances of your vehicle.
