You need to give us more information...

That is like asking why a puppy shits on the floor... there could be a number of reasons.

A P0170 Fuel Trim Malfunction is thrown when the ECU fuel compensation value goes out of range high or low. Listed causes are MAF failure, Injector failure, bad fuel pressure, vacuum leaks, O2 sensor failure, Engine Coolant Temp sensor failure, Exhaust leaks.

Simply, it means that the ECU thinks your getting too much or too little fuel and can't adjust anymore for the difference by using it's fuel trims.
