Hi i have a 02 v6 bird and today i cranked it up to let her warm up and after the normal 15 minute warm up time i got in it to go to work, and had no power, also the "REDUCED ENG PWR" was on. it has done this once before about a month ago and after leaving the car all day it ran fine with no problem again till this am.
i guess there a problem since it has this light which seems to not be on the v8s
any insite would be awesome! thanks & emails are ok

A bad fuel pedal sensor will cause the system to go into "limp mode" . It might also be called a throttle control valve.

would it be extremely intermitant?
Those things don't exist. That was a troll GW

I fixed my dads 2003 Trailblazer by replacing the Throttle Control Valve. His "Reduced Power Light" is no more and vehicle runs great. His problem was intermitent. Thats it! say what you will.
ugh do u think a gremlin/troll woulda happened twice??? same senario two months apart...
luckly enough i had an extra car to drive those days, cause it wasnt driveable...its just sooo frustrating to know that it just may happen some time, no warning or cause...
That's not what it's called.
I got this from work: "Throttle Actuator Control (TAC) System Description
The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions: ? Accelerator pedal position sensing ? Throttle positioning to meet driver and engine demands ? Throttle position sensing ? Internal diagnostics ? Cruise control functions ? Manage TAC electrical power consumption
The TAC system components include the following: ? The accelerator pedal position (APP) sensors ? The throttle body assembly ? The throttle actuator control module ? The powertrain control module (PCM) "
No "fuel pedal sensor" no "throttle control valve" GW
Throttle by wire is scary as hell. GW

actually Geoff...there is a throttle control valve and a fuel peddal sensor (throttle postion sensor) in the TAC system. The valve is located on the side of the throttle body and the postion sensor is located inside the vehicle at the accelerator pedal. Sounds to me Jess that the postion sensor got water/muck into it like a lot of them have been getting. I have had to replace 6 of them on diesels (same system idea is used..no throttle cable)..and had the same L.O.P. light.
If you think an APP (not "fuel pedal" which is a ridiculous fake name) and a TPS are the same thing then you are totally lost. Use "actually" all you want, you are still wrong. GW

oh well..guess my working on diesels the last 15 yrs where none of them have a throttle cable (they run the TAC system) makes me wrong. Just wonder what book you read to get the understanding of the system. Good luck to you Jess
GENERAL MOTORS Service Manuals. Who cares what deisels call their parts??? This is a PONTIAC group.
Thanks, but I don't need luck, I have the proper info. GW
