Just got a note from GM about a posslible defect in the fuel tank pressure sensor for these model years.

This is a safety recall and not a TSB.

The dealer will either replace the fuel tank pressure sensor and/or the whole fuel tank and charcoal cannister.

If you own one of these vehicles, and haven't been notified yet, give your dealer a call for more details.

Any more info on this? Models affected?

Have late 2003 SSEi and have heard nothing from GM.

Here you ALL go!
Product Safety - Fuel Tank Pressure Sensor #03038 - (10/10/2003)
03038 -- Fuel Tank Pressure Sensor
2002-2003 Cadillac DeVille, Seville

Equipped with V8 (4.6L) Engine (LD8/L37)

2002-2003 Oldsmobile Aurora

Equipped with V8 (4.0L) Engine (L47)

2002-2003 Pontiac Bonneville SSEi

Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2002-2003 model year Cadillac DeVille and Seville vehicles equipped with a V8 (4.6L) engine (LD8/L37), Oldsmobile Aurora vehicles equipped with a V8 (4.0L) engine (L47), and Pontiac Bonneville SSEi vehicles. The fuel tank pressure sensors in these vehicles are unusually susceptible to malfunctions. If the sensor malfunctions, excessive vacuum can be applied to the fuel tank 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 fuel odor from the fuel tank area, inaccurate fuel gauge readings, and poor driveability. If there is an ignition source present, a fire could occur.

Correction
Dealers are to replace the fuel tank pressure sensor, and if required, the fuel tank assembly and evaporative emission canister.

Vehicles Involved
Involved are certain 2002-2003 model year Cadillac DeVille and Seville vehicles equipped with a V8 (4.6L) engine (LD8/L37), Oldsmobile Aurora vehicles equipped with a V8 (4.0L) engine (L47), and Pontiac Bonneville SSEi vehicles built within these VIN breakpoints:

October, 2003
Dear General Motors Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Federal regulation requires that any vehicle lessor receiving this recall notice must forward a copy of this notice to the lessee within ten days.

Reason For This Recall
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2002-2003 model year Cadillac DeVille and Seville vehicles equipped with a 4.6L V8 engine, Oldsmobile Aurora vehicles equipped with a 4.0L V8 engine, and Pontiac Bonneville SSEi vehicles. The fuel tank pressure sensors in these vehicles are unusually susceptible to malfunctions. If the sensor malfunctions, excessive vacuum can be applied to the fuel tank 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 fuel odor from the fuel tank area, inaccurate fuel gauge readings, and poor driveability. If there is an ignition source present, a fire could occur.

What Will Be Done

one of the cars im thinking about getting the vin number is 34155557 so is that car part of the recall? if i reading it right it is, so what should i do if i decide to buy this car, ill tell ya this board is so helpful in finding info on these cars for sure

Point it out to the dealer. Make it part of the sales agreement that any and all recall and TSB work is done before you take ownership. The recall stuff will be easy, you may have to haggle over the TSB stuff.

OK, looks like we lucked out. 03 SSEI VIN 34178678 so apparently they fixed it online sometime past middle of model year run.

Makes me curious about production runs. Looks like 58k in 02 (if it starts at beginning of year), 78k+ in 03. Do you know if that'* all SSEi'* or includes all Bonnevilles? Food for thought anyway.

How does one get a list of the TSB'* (Tech service bulletin?) for a specific model year? Might be interesting.

Thanks for you're efforts and information

Ned K

I get them from GM myself....I work for a Pontiac Dealership in the Parts Department.
I've got access to all of GM'* database for Service Information (TSB'*, Campains, Hot Tips) too.
Here will give you a list of all the particular TSB'* for any vehicle, but you'll still need someone to actually access the GM Database to read that TSB though.
