code p0128 refers to coolant thermostat--coolant below thermostat regulating temperature==causes mechanical fault. ( thermostat stuck open --replace it) If you are experiencing cold weather then there is a problem with the ecm settings as the ecm should be compensating for the cold ambient temperature and setting the fuel mixture to richer than normal ( same as using a choke). Check the fault codes again and check for a coolant sensor fault.

04 chevy trailblazer code po172?


System running rich. Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). Bank 1 is the side of the engine that has cylinder #1.

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.

Chevy trailblazer check engine light


P0128 is coolant operating temperature operating too low. This can be contributed to the Thermostat stuck open or faulty electronic radiator fan clutch. This is common, I had the same issue and replaced the thermostat and fan clutch and had the clutch re-programmed (required) at the dealer. As for the P0410, check the air pump fuse, if blown it will set this code on. Also check the air pump hoses for water and cracks. Hopefully this helps!!

I need the location for a coolant sensor on a 04 chevy silverado truck


You didnt say what size of engine you had, but in 5.3L the coolant temp sensor is located on the driver's side of the engine, just in front of the exhaust manifold. If you have a different engine, just leave a comment on here and i will update the location.

At what mileage should the coolant be changed in a 04 Chevy TrBl?


Renew the coolant every 24,000 miles or 2 years which ever comes first.
If your battery is in good condition, there is no need to change it.
