You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

That is the code for fuel system or O2 sensor. Replace the O2 sensor and reset the error code by pulling the ECU fuse for several seconds.

If the error returns, the problem may be in the fuel supply, such as clogged filter.

RE Tim's suggestion to go get a manual: I would suggest a Helm manual. It is about $50+ but worth it.
