I have a 2003, and the fuses are located on the drivers "end" of the dash. Open drivers door and you should see removable panel.
That would be the drivers side of the engine.
Trouble code P0174 means:System too lean (Bank 2)
From what i read, the bank one sensor is on the driver's side of the exhaust manifold. Bank one refers to the first cylinder.
stand up face to face in front of the engine ,your left side is Bank 1 (firewall) and the right side is Bank 2 (radiator side)
behind the block under distributer
Setting in the seat, Bank 2 is the right side of the engine.
it is the rear sensor bank 1 (the one after the converter)
That would be the drivers side of the engine.
The 1999 Chevrolet Tahoe exhaust diagram, for bank 2, can be obtained from most Chevrolet dealerships. The diagram can also be found in the owners manual.
Sensor 2 is the one after the catalytic converter. Located strait down under intake.
Is this bank 2 sensor 1 or sensor 2?
One could locate their bank routing number by simply calling, or going into your bank and asking for it. They will tell you. Alternatively, you could probably find it in your documents at home.
