Your Trailblazer's ECM has detected an issue with your engine's performance and has reduced the power till the issue has been addressed. Auto Zone can scan your Trailblazer for the DTC codes and can give you the recommendation for you to address the issue causing your engine to reduce the power. There are just to many things that can cause the engine to reduce the power, so the best bet is to have it scanned and Auto Zone scan free of charge. Good luck and hope this helps.

Did you plug it in to a computer scanner? It will tell you a code and the dealer can tell you what it means or you can try to get a hanes manual at your local parts store and that lists almost all the codes.

Check engine light came on then reduce engine power


When this light comes on it means the computer control module has detected a fault in the system, it has reduced power to avoid any damage to the engine or transmission. You must now have the computer scanned for fault codes, this is done through the diagnostic connector under the dash see photo below.

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

I have a 2003 Cadillac CTS. It continues to go into reduced power mode. How do I correct that.


Are you getting a ENGINE POWER REDUCED message ? Is the check engine light on ?
Reduced Engine Power Mode
Throttle Actuator Control (TAC) System
electronic throttle control .
When the ECM detects a condition with the TAC system the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Limited torque


?€¢
Limited range of throttle movement


?€¢
Engine OFF


Your going to need to take this to a ASE certified repair shop or the dealer , you probably don't have the diagnostic tools to trouble shoot this problem.
