The error code 0170 and 0173 are related to Mass Air Flow (MAF) sensor. Check for any vacuum leaks and repair them if found. Else changing the MAF sensor may resolve the issue.

IT MEANS THAT YOUR OIL LEVEL IS VERY LOW AND NEEDS TO BE FILLED. CHECK THE OIL LEVEL WITH THE DIPSTICK IF EQUIPPED. IF NOT, THEN ADD 1 OR 2 QUARTS OF OIL TO SEE IF THE OIL LIGHT GOES OFF. IT MAY TAKE SYNTHETIC OIL SO DON'T PUT CONVENTIONAL OIL IN IT IF YOU SEE A MOBIL 1 SYNTHETIC OIL RECOMMENDATION STICKER UNDER THE HOOD. IF YOU ARE UNSURE THEN BRING IT TO A QUALIFIED TECHNICIAN A.S.A.P.. HOPE THIS HELPS. GOOD LUCK.

A couple of ways to check and see if the computer is ok first:
check engine light must come onwith they in on position
The fuel pump must run for two (2) seconds with the key ON
There must be a 5 volt reference at sensors like map, TPS
Must communicate with scan tool
The ORANGE wires at the computer are you power input wires one has 12V all the time this is your KEEP ALIVE MEMORY
one is 12 with the Key on you MUAT HAVE VOLTAGE AT BOTH
Check the computers Ground most are out under the hood and are brown wires
Try the GM TAP TEST this is a factory authorized test with the computer connected and you verified all of the above SLAP the computer with the open hand firmly not too hard but firm see if anything changes,
Do not disconnect the battery you will erase all the codes!

that appears to be a camshaft position sensor performance code. you can start by checking to see if the sensor is working properly, re-check and make sure that the harness is ok by checking the resistance through the harness if all looks well there make sure the computer has the latest software on it by having it scanned at your local dealer. also you can check the reluctor wheel on the camshaft for damage or debris in the way of the sensor.
hope this helps!

With the key in position 1, hit the odometer reset button on the left on the cluster 3 times in a row. The cluster should beep once. scroll through the multifunction display with the page buttons until the display shows the onboard voltage screen. It will say something like "UB: 12.2 V" scroll threw this menu with with the up/down until you reach the "service menu" page. scroll down to "confirmation" press +, confirm full service with +. Wait till it says service confirmed. cycle the key off and then back on to position 2. Scroll to the normal service menu where it normally says how many days or miles till next service. If the service was reset correctly, it will say "service display not possible" for a few minutes while it recalculates. You must cycle the key off and back on before it will back out of the onboard diagnostic mode. If you dont back out, the esp/abs/bas lights will illuminate when the car is started
