SOURCE: 02 Oldsmobile Bravada check engine/reduced egine pwr light on

There are over 2000 different trouble codes that can store with your check engine light. Probably 30-50 of them (or sequences of them) can trigger limp-mode or safe-drive mode on most vehicles. In your case, I would strongly suspect a problem with the electronic throttle control assembly. For safety, vehicles with electronic throttle frequently limit speed and rpm to very low numbers when a fault is detected to prevent runaway accelerations and high speed collisions. Have it checked by a professional. It may be as simple as a sensor on your accelerator pedal, or the throttle assembly itself could be starting to fail. In either case, it shouldnt be played with unless you have the proper diagnostic equipment (a Tech-2 Scantool) and good repair data.

NOTE: Clearing the code with a generic tool or disconnecting the battery MAY allow the car to reset, and if the problem is intermittant, it may become normally drivable till the next time thr problem occurs. HOWEVER...the technician who fixes the car really should have access to the original failure information stored in the freezeframe snapshot the computer took when it set the code. If you reset the light or disconnect the battery, that info will be erased and make make diagnosis and repair much much more difficult.

If it has been serviced correctly just take it aback and ask them to reset the warnibg light. If they can't then you should chose another garage to service it.

without knowing the trouble code that is set in memory anytime the check engine light comes on there is no way to know the problem or if there is a fix under any type of recall, there are over 200 fault codes poss in this system, have it tested for which code turned the light on.

Got up this morning and started my 2004 olds bravada to see the ''reduced engine power'' light on and the ''service engine soon'' light on! Had just got a full tank of gas from Safeway, so thinking it was...


Is the check engine light on also? Your bravada is in limp mode (it is restricted to 2k rpm to protect the engine from damage, due to a problem), something is going on, so go back to auto zone and have them check for any codes (free service). They can tell you what the codes mean and suggest what you should do. If you have questions, post them here with the code #'s.

Key will not come out. Battery light stays on.


your shifter is not aligned properly this condition indicates that the shifter has placed the transmission in park but just barely it needs like maybe 2 more millimeters of travel.
