Reduce engine power light comes on 2005 buick lacross


The check engine light n or reduced power light comes on when the on-board computer detects a fault in engine driveability or performance, transmission control system or transmission, or the emissions system, and a fault code is set and stored in the computer. Faults that can set the check engine light can range from a vaccuum leak, engine mis-fire, low engine compression, faulty sensor such as O2 sensor or other engine sensor, hydraulic pressure loss in transmission, transmission shift solenoid, open/short in wiring harness, emission evaporative system leak, or one of over a hundred different reasons. The only way to know what set a fault code and turned the check engine light on is to have a diagnostic scanner hooked up to the on-board computer and read it for stored diagnostic fault codes. Many auto parts stores will do this service for free- (like auto zone)check with you local parts stores. If none in your area do, then you will have to take it to a shop and pay to have the computer read for stored fault codes. Without knowing the fault codes numbers, it would be irresponsible to guess as to the cause as there are hundreds of possible causes.

My engine light came on it said engine power reduced check esc transmission off


What is the year make and model of the vehicle? If the "check engine" light is on that means the vehicle is trying to tell you that there is a problem and the codes need to be scanned. If you can safely drive it to an auto zone or advanced auto they will scan the codes for you for free. You should get a fault code(s) that starts with a P then four numbers, ex. p0601. These codes will basically tell you what could be wrong in the car. I personally recommend that once they scan the codes, have them clear the codes then scan it again to see which codes, if any, come back. The more info from you, on something like this, the better.

If you take it to AutoZone or Advanced Auto Parts and they can run a free diagnostics on it. They will get a code which you can look up and find out what is causing your check engine light. Once it is fixed your check engine light will stop coming on.

Hope this helps.

Check engine light came on and reduced power light. Car would not idle or run smoothly. turned it off and waited. started up and ran for 10 miles. Then same thing.


Thanks for choosing FixYa and welcome. There are many things that can cause your check engine light to come on. When it does come on, this means the computer has detected a problem with the vehicle. Every car has this system. Anytime it is on, you can usually get a code number off the computer scan. The hookup is under the dash in most cars. You can buy a cheap one for around 50 dollars at most auto part stores. If you do buy one, you may need to find what each code means. If you don't own one or you can't get to one, you can take it to Autozone or Advanced Auto Parts to get your vehicle scanned. Most places do not charge for the scan. Autozone and Advanced Auto Parts do not charge when your check engine light is on. They will be able to scan it for you and give you the codes. They will let you know what it says and what parts you will need as well. if you ask. If your check engine light is flashing, this means there may be internal engine failure. If this is your case, get it scanned as soon as possible. The longer you go with the light on, the greater the chance you have to make the problem worse. Some of the newer vehicles has this system already built in. You will need to know sequence though, to make the code appear

Car keeps stalling out along with reduced power and check engine


you did not id what year/make/model but it sounds a lot like a typical failure of the MAP

however, depending on your year/make/model the code could also be a sign of an power concern to your PCM, (powertrain control module) aka computer

P1239


i have gone on the internet and looked up the code
however there was 3 2 different meanings to this one code
you need to check all oil levels as it is a warning for oil pressure as well as the throttle body
check the transmission motor oil power steering etc
if these are all fine then there is some trouble with the throttle body this is what i would pin it to.
it should be OK to drive home just be very careful keep it slow and try to stick to one speed
if it is the throttle body you will need a new one any way
if you have cruse control use it as it will keep the motor steady
avoid any harsh breaking or execrating as this makes tension KEEP IT STEADY DRIVE SLOW ABD YOU SHOULD BE ABLE TO GET HOME DON'T GO OVER 80KPH SO ABOUT 71MHP.
don't overtake don't apply power and dont use the aircon if you can help it as this all adds presure to the throttle body
if the throttle body breaks it will not damage your motor as i said you need to get it fixed any way so you cna take the chance
the worst that will happen is you will not make it home and your car wont run till a new throttle body is put on
we have a 2005 holden rodeo at work same as isuzu and we have had this problem it was the throttle body it is ine thing that is commen with in these cars
hope this helps
good luck getting home safley
