Adm Msg - 2004 Grand Prix with DTC P0455 Fuel Tank Pressure Sensor

When a technician is diagnosing DTC P0455 and a Fuel tank Pressure sensor replacement is suggested by the strategy-based diagnostics, dealers are advised to order Fuel Tank Pressure Sensor P/N 16238399 instead of P/N 09377680.

Fuel Tank Pressure Sensor P/N 09377680 has proved to be unreliable and it is likely to fail again shortly after installation.

Production change to use P/N 16238399 is scheduled for mid-April.

For your reference, a TAC PI is in process and parts are available in stock at GMSPO.
