This bulletin is being revised to add VIN breakpoint information for the 2000 Chevrolet Cavalier and the 2000 Pontiac Sunfire as well as to clarify the
applications for the fuel sender-to-tank 0-ring. Please discard Corporate Bulletin Number 01-06-04-007 (Section 06 - Engine/Propulsion System).
Important:
This bulletin only applies to vehicles built after the above VIN breakpoints shown. The early 2000 Chevrolet Cavalier and Pontiac Sunfire models
were equipped with metal gas tanks. The bulletin and seal listed below are only applicable to vehicles equipped with plastic gas tanks.
Important:
All year 2000 Oldsmobile Alero and Pontiac Grand Am models were built with plastic gas tanks and are covered by this bulletin.
Condition
Some owners may comment that the Service Engine Soon Indicator lamp has come on. When the vehicle's stored code is read with the scan tool, DTC
P0442 is found. This code indicates that the evaporative emission system has found a loss of fuel vapor.
Cause
The 0-ring seal between the fuel tank and the fuel sending unit may have become rolled or pinched during installation.
Correction
Important:
DTC P0442 may be set by any point of system fuel vapor loss. This includes a loose gas cap. Be sure to identify any possible simple points of system
vapor loss before replacing the fuel tank 0-ring.
Replace the sender-to-tank 0-ring with revised seal, P/N 22626099, using the procedure found in the Service Manual. Refer to Replacement of the Fuel
Sender Assembly in the Engine Controls sub-section which includes the procedure to replace the sender-to-tank seal.
