manuals with trouble charts to follow

You need a professional scan tool, almost always ,to get not
just Generic but Enhanced codes

You have to road test to gather & look a all Data

You have to review the data & come up with your component
testing strategy, just to find a problem,anything,correct it &
continue on

Code 155 is for a problem with the heater circuit in the O2 sensor for bank two. Bank two is on the side with cylinder number two.
Usually the sensor is faulty, but the heater circuit would need to be checked to be sure. The sensor has a built-in heater to get it hot quickly after starting the engine.

P0128:
P0128 OBD-II Trouble Code
Technical DescriptionCoolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)

What does that mean?This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125

In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.

CausesA code P0128 may mean that one or more of the following has happened:

Low engine coolant level .
Leaking or stuck open thermostat .
Faulty cooling fan (running too much) .
Faulty coolant temperature (ECT) sensor.
Faulty intake air temperature (IAT) sensor .Here's a link on replacing your thermostat.

Check engine light comes on and off, these are indication that there is some error code stored in your vehicles ECM. The engine module computer needs to be scanned. These will give the code and as per the error code the further problem can be detected and confirmed. The engine light indicator blinks or remains steady on dash when engine computer noticed any problem with any engine electrically operated components.

For more help, I suggest you to refer the help links provided below. These will let you know more about which areas to look, check, when there is engine light coming up on dash panel.

Thanks.

The P0014 code refers to one of your camshaft position sensors being out of time with the other. Does not mean its bad but it could be. The P0128 code refers to your engine running cooler than it should. Your coolant thermostat may be stuck open not letting the engine warm up to it's proper temp. Now you did not say which engine you have in the TrailBlazer. There are 2 different engine used in the year model. Please repost with that info.

Sounds like the thermostat may be stuck open or has anyone put a colder thermostat in the car,because once it starts to get cold it will throw a SES with a colder then stock thermostat.

Code PO128; coolant temp below thermostat regulating temp. Replace the thermostat and that should address your issue.

Thank you for using fixya and good uck

This has to do with the secondary air pump system, this system is used at cold start-up and involves three components; air pump, solenoid valve and a relay. Many times the valve becomes stuck or clogged, the relay has also been known to fail.

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 secondary air injection comes from an electric air pump (replaces the old eng. driven smog pump), it seldom runs, but when the car is 1st started you should hear if for about one minute, kinda sounds like a muffled hair dryer. The most common issue is the hoses get knocked off, 2nd is the electric motor failing.
