As we know The Jeep Liberty is equipped with the OBD 2 system which stand for second version of on-board diagnostics because it was manufactured after 1996. This newer car diagnostic system standardized the location of the data link connector (also short for DLC) and the diagnostic trouble codes (also short for DTCs). This simplified the process of diagnosing faulty sensors or modules in the car that communicate to the car's computer system. When a faulty DTC is detected in the Jeep Liberty's computerized system, it will activate the Check Engine Light (also known as the malfunction indicator light which short for MIL), showing an engine code has occurred.
Youll Need Pocket scanner and Owner's manual for pocket scanner for this job.
Open the driver's side door of your Jeep Liberty car and find out the diagnostic link connector (short for DLC) under the instrument panel. It is generally located to the right of the steering wheel on the Jeep Liberty.
Insert the pocket scanner into the DLC and then turn the ignition key to the accessory position. This action will power all the electrical controls on without launching the engine. The scanner will obtain its power from the battery in the Jeep Liberty and turned on automatic.
Read the onscreen menu of the scanner. While there are a lot of types and designs of pocket OBD scanners, in general they are fairly universal in terms of operation. Most will feature some items on the menu that you can scroll between and press an enter key to activate the function. If you're having trouble operating yours, you can look up the scanner owner's manual.
Select "Erase" option and similar item. On some models, there may even be an "Erase" button. Simply press the button if that is the case on your pocket scanner.
Wait until the onscreen menu has displayed "Command Sent" or has defaulted back to the main menu. Launch the engine to the Liberty to confirm if the "Check Engine Light" is out. If so, the engine codes are erased. If not, further diagnosis is required; you may ask a mechanic for help if it is out of your ability. If you have any query, please do not hesitate to contact me.

It means somebody didn't know how to use their code reader at Autozone. The first 2 codes you listed are not valid OBD II codes for your vehicle. P0118 is Coolant Temp Sensor (ECT) voltage too high. It usually sets when the coolant temp sensor is unplugged or a wire to it is broken or shorted to voltage but it can also set if the sensor is bad. Hope this helps and good luck!
