2003 Chevy Trailblazer engine power lose light come on


Hi Steve , your vehicle has electronic throttle control . I don't know if you are aware of this. The gas pedal have position sensors an a wiring connector with 4-6 wires .these wires are connected to the engine computer . an there is a electric motor on the throttle body assembly , the computer opens an closes the throttle . You probably have codes stored in the engine computer .
Reduced Engine Power Mode When the PCM detects a condition with the TAC system the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.

?€¢
Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.

?€¢
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.

?€¢
Forced idle mode--The control module will perform the following actions:

-
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.

-
Ignore accelerator pedal input.

?€¢
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.

The reduce engine power light has came on I have a 2002 Chevy Trailblazer, what does this mean?


A lot of times it's a filthy or sticking throttle body. With this situation, the computer will throw the reduced engine power light as kind of a safe mode. A lot of times, you won't be able to go past a certain speed too. With the battery disconnected, clean your throttle body with throttle body cleaner. Must be shiny. When finished, drive around for 20 minutes or so, so your computer can re-learn the correct settings of a newly cleaned throttlebody. When driving for 20 min, make sure all accessories are off.

The 'check engine' light and the 'reduce power engine' light came on on my 2002 chevy trailblazer what could this mean?


A sensor failed. A code will be stored. You need to get the code in order to proceed. With over 200 possible codes its anyones guess what happened.

2002 reduced engine power light


You have some kind of ECU problem. You will need to hook to the diagnostic port to find the problem. Your vehicle has gone into limp mode. This enables the vehicle to run, but at a diminished level until you can seek help for the problem. Do not continue to drive it this way as you may cause damage to the engine depending on the nature of the problem.
