2003 Pontiac Bonneville

On certain Aurora, Bonneville SSEi, Devile and STS vehicles, the fuel tank pressure sensor is unusually susceptible to malfunctions causing excessive vacuum to be applied during self-diagnostic testing. Fuel system components can be damaged and fuel can leak from the vehicle when it is refueled. Possible symptoms of this condition are illumination of the Service Engine Soon light, poor driveability, increase noise from the fuel tank area, and inaccurate fuel gauge readings. If there is an ignition source present, a fire could result. Correction: Dealer will replace the fuel tank pressure sensor.
