Question about Buick LaCrosse

Reduced engine power

My 2006 will turn over for a very short while, will chug and lights will flicker. After that "Reduced Engine Power" is displayed along with the check engine and no TC lights and the engine will shut down. After the engine quits all lights will be fully powered. What do you think is wrong?

    I guess the only problem is moving it because it's entirely immobile at this point.

SOURCE: 2006 Chevy Impala reduced engine power

best bet is to stop in at a Pep Boys, Autozone, or similar big autoparts seller, and ask for free trouble code scan, which should pinpoint area causing problem. If not obvious by codes, what is necessary to repair the problem code, get back to us with those codes and we will be glad to assist you further. Better this way, takes away the guess work, and saves you money, as well as getting it right the first time.

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 siddiq_pathan@yahoo.com. Thanks. I am an auto technician and working in a GM dealership in Saudi Arabia. I am from Pakistan.

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

Engine power reduced displayed


sounds like the camshaft sensor or the crankshaft sensor, either way I think your car is being recalled for a faulty ignition switch which could turn off by itself.

Coolant message,n reduced engine power light is on, wont start


Your battery is too weak to turn the starter. The starter takes much more power than the lights or anything else.
