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.

Locate the IP to body harness connector, which may be located in and around the left hand kick panel area or inside the IP. Check to see if there is a water leak into the area and repair as necessary.

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.

'Engine power reduced' comes up along with check engine light. Replaced throttle body the other day but it happen again! Anyone know what is going on and what could be causing this?


check engine lights notify problems in 2 areas . firstly the engine and also the transmission.As you state a problem in the transmission it is possible that is the area of concern. A service dealer will be able to tell you exactly what the sensor fault is for that code.

Reduced Engine Power and then died


If it does it again go to a auto parts stor and ask them to put the scan tool on it and get the codes pulled. Write them down and post them on here. You may be able to get codes now. It probably stored the codes in the cars computer.

Cvt light on indicating over heating. Stops car lets it cool down and then completes his trip. Dealer could not identify problem or diagnose the problem.


I do not know why your local Mitsubishi dealer cannot figure this one out. What you are describing is a known problem for which Mitsubishi has published a Technical Service Bulletin (TSB).

The problem is caused by incorrect transmission fluid levels and there is an updated dipstick included in the fix.
MITSUBISHI TSB REFERENCE NUMBER: TSB-10-23-005

You may also want to talk to your son about heeding warnings from your vehicle's onboard computer system. When the CVT transmission begins to overheat, the CVT light will come on, a warning chime will sound, and the words "SLOW DOWN" will be displayed in the Muti-informational Display. This will occur LONG before the vehicle goes into "REDUCED POWER" mode. If he would slow down as he is being told to, the warnings will extinguish themselves as soon as the transmission fluid temperature drops to a safe level (which it will, if he slows down).

REDUCED POWER MODE is like an angry parent...."OK, you don't want to slow down like I told you to do, and you are going to destroy my transmission by ignoring my warnings, so I am shutting you down!!! You won't slow down, so I am slowing you down! Now, if you do not want this to continue, then you better start listening to me!"

Similar things will happen if you choose to ignore engine control or Brake/Traction Control warnings. The old days of ignoring warning lamps and running around with your dash lit up like a Christmas tree are over. There is a new sheriff in town called REDUCED POWER MODE.

I have a 2003 Envoy- GMC. Why does the reduce engine speed light come on


you need to scan you vehicles ECM, there is a trouble code stored there. depending on where you live most parts stores( such as a shucks/orielleys) will have a scan tool they will let you use if the vehicle is in thier parking lot. this should diagnose the issue, provided the battery hasnt been disconnected since then.

I have a 2003 Chevy trailblazer,when I accelarate my service engine soon light came then the reduce engine light comes on; suddenly my truck slows down. Shut the engine down, start it back, the lights go...


Get the engine codes pulled. Once you have them it will help track down the issue. Not really much you can do otherwise unless you want to throw money at it.

LIGHT COMES ON SAYS REDUCE ENGINE POWER THEN TRUCK SLOWS DOWN SO I TURN OFF THE TRUCK TURNIT BACK ON THEN TRUCK RUNS NORMAL WHATS GOING ON


I'm pretty sure the computer is calling for the 'limp home' mode and if it is, some potentially damaging circumstance is causing it. The chain auto parts stores will scan your computer free and this will give you a code (or more than one) revealing generally what the problem is.
Give the nearest one a call to confirm that they still do that free.

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
