If your lucky, your car is still under warranty. If your warranty is over, you can go to Auto Zone and have the car scanned for the DTC codes.

SOURCE: need to know what the "reduced engine power' MIL

this is one of two things, first theres a problem with the engine , the way it runs its loosing power or if the wheels spin and the computer picks it up then it will reduce the power to avoid wheels from slippping, this is like when driving in the snow, now if the check engine light is coming on with this message then you have a problem and the first thing to do would be to have the codes pulled and see what codes are stored. what happens is the computer sees a problem and turns on the light and stores a code for that problem. for example there may be a code that reads po300 multiple misfires. this code would mean the computer has seen the motor misfiring and with some testing the problem can be found. there are many auot part stores that will scxan the computer for free and give you a read out with the code. if you get the codes i can help you further, have a good day.

The car says engine power reduce how can I reset that it's a 2004 Cadillac cts 3.6


Engine power reduced means it has a problem with the electronic throttle control system . You can't reset it , has DTC"S- diagnostic trouble codes stored in the computer . Something is worn , a position sensor in the gas pedal assembly or throttle position sensor on the throttle body . Your best bet , take it to a qualified repair shop ! or the dealer .

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.

I have bmw 318 08 reg problem is indicating engine fault. Loss of power can u solve this problem.


Hi Anon
To find out what the problem is, you will have to get the code read as this will indicate what the fault is, when the engine management light comes on it could be 1000's of different things, so each error has its own code, you will have to take it to a garage or dealership to enable them to connect a diagnostics reader to your vehicle, reduced power is telling you , you can only drive it slowly as there is a fault and it is not 100% sure what the fault is ( car computers are not intelligent they just know something is wrong ) so it is saying reduce your speed until the fault is fixed. hope that halps

My 2004 pontiac grand prix gtp has twice now thrown reduced engine power across my dash and acts like it cant get any gas and comes to a stop. Does anyone know what this might be the first time I figured...


Have the fault codes read as a reduce power message means that something is wrong either in the engine or the gear box. check oil and coolant levels and treat the message seriously as it is intending to stop costly damage

Neither the Throttle Body or the APP (Gas Pedel -that never fails)

Who diagnosed & replaced all that?

Do you have cylinder misfires (bad coils)?

What codes were there when whatever happened
first started?

What does engine power reduced mean? hhr 2006


It reduces power to protect from engine damage. I have had this happen twice because I accidentally hit the back of the gas peddle up when I was in cruise control. It will reset once you drive in reverse. If that does not resolve the problem you might have to take it in for service.
