What do I need to do to fix my 2005 trailblazer. its reading a code po128

Change the coolant temperature sensor. If the code is still there, change the thermostat, it might be stuck open causing the engine to run cooler than it should.

The temperature display on the rear view mirror shows OC

The temperature display on the rear view mirror my 2002 Trailblazer LT is either way incorrect - like obviously too high or too low - but mostly just shows "OC" all the time. Is this an expensive fix? Is this an easy fix that I could do myself? What do I need to replace and how

I have a code of p106 barometric pressure sensor

This is where a DUI guy can get into unnecessary expenses.There are causes of this code that are independent of the sensor. There has to be correct voltage going to the sensor. As well, the sensor also has to have a good path to ground. The sensor could be sending an accurate value to the computer.Low manifold vacuum can set this code too. If there is a vacuum hose running to the sensor it could be kinked,cracked or plugged with sludge or carbon.The sensor only sends what it senses and these will give false codes.
