Engine management lights on with reading engine fault, reduced power
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

HI...
THis problem is caused for
Lost of correlation between ACELERATOR PEDAL POSITION
AND THROTTLE ACTUATOR MOTOR.
Because your car has no acelerator cable.
The morer probable is the Trhottle actuator motor come damaged. 90%. 10% the accelerator pedal position.
If you turn of the car it will work OK> for a few time.
But the Service engine soon. will stay on.
Yuo can go to at ANy ADVANCE AUTOPART, AUTOZONE or NAPA AUTOPART. They make a diagnostic free.
If not. I recomend get the car scanned for see exactly why the light come on. and make the right repair procedure.
OK>> I hope this help on your question...
Thank you for use fixya.

SOURCE: SES light then Reduced engine power light, loss of engine power
Hi It me Mohammad Siddiq my dear. First of all it will be wise of use to take your vehicle to a dealership or any other fully equipped w/shop. They can better tell you what the fault your vehicle has. But at the same time if your friend has the same model vehicle so you can exchange some parts with that vegicle, e.g., Mass Air Flow or TPS (Throttle Position Sensor) and can check your vehicle. These parts do not need to be programmed with scan tool. Just Simply replace these parts and switch on the ignition and wait for 01 minute, then switch off for 30 seconds and then start the engine. Now road test your vehicle, if no SES light or reduced power then there was fault with the part/s replaced. So Return those parts and now you must replace these parts with new or used ones. Anything else I may be contacted on my yahoo id [email protected]. Thanks. I am an auto technician and working in a GM dealership in Saudi Arabia. I am from Pakistan.
