Code P0452 on a 1998 Buick LeSabre indicates a fault with the fuel tank pressure sensor. This sensor measures the pressure inside the fuel tank and helps monitor the evaporative emissions system. The issue may be due to a faulty sensor, damaged wiring, or issues with the fuel tank itself. It is recommended to have the sensor and its wiring inspected and tested to determine the exact cause of the problem.
