Error codes P1159 P1161

Anyone have a list of what certain error codes are for? I ran a scan with my OBDII and got error codes P1159 and P1161.
Thanks

Fuel Trim in each bank. (1 & 2) Could be O2 sensors or software related.

Air-fuel metering. Likely some bad hoses in the MAF system (vacuum). Remove plastic engine cover and check two hoses at rear of engine, left of center. They are about 2.5cm in diameter and perhaps, now, a gooey mess of torn rubber. (Mine were, after 105K miles; and as part of a general rebuild of the front-end: alternator, battery, water pump, serpentines, thermostat, O2 sensors, battery and lastly those smelly hoses. If you've a good nose, you'll smell "whispers of gas", when those hoses are in bad shape // X5, 4.4i, 2002)

You can find OBDII codes in any search engine...
