from the service manual (1998): HO2S Ckt Low Voltage Bank 2 Sensor 2

I believe this is the passenger side aft of the cat.

The PCM sets this code:
the vehicle runs out of fuel
HO2S wire: Sensor pigtail maybe in contact with the exhaust manifold or exhaust system
The wire may be broken
intermittent ground in signal wire between connector and sensor
Lean injectors
Fuel contamination
Low fuel pressure
Exhaust leak near the HO2Scan cause a lean condition. Vacuum or crankcase leaks can cause a lean condition.


So, I guess you have a little bit of diagnostics to do. Others may have more relevent information for you.

Is there a way to test my fuel pressure?

Fuel pressure guage can be connected directly to the schrader(sp?) valve on the front of the fuel rail.
