The code is low circuit or voltage to throttle position sensor I changed the TPS I checked the voltage to it clean the throttle body and the egr valve took off the upper intake manifold I also replaced that and the gasket.. I changed the map and maf sensors I change the PCV valve and check the fuses to the ECM.. also because I was having a random misfire I did all of that and change the spark plugs coil packs and wires.. I thought the sluggishness was due to this but it had nothing to do with it..my symptoms are pretty much you can't drive the car it doesn't go anywhere hardly gets up to 30 miles an hour apparently when this code triggers it puts the car in fail safe mode I'm wondering does anyone know is there a sensor on the accelerator pedal ?? Or does anyone have any suggestions for me any kind of help would be appreciated again it's a 2001 Grand Prix GT sedan
That signal voltage going low is the only thing that causes that code.
Excellent thank you for your input !! I do have a cheap $35 scan tool I got on Amazon.. I'll see if I can pull up the live data on it see if it gives me the voltage otherwise I'll just use my multimeter like you said.. quick ollow-up question before I get into this tomorrow... Do you know if the 2001 GT has that feature where it will go into "failsafe mode" or "limp mode" when an important component or sensor goes down or isn't receiving the proper voltage ?? I've researched it a little and I haven't found any litature that says this particular model has that feature as a safety mechanism.. but the symptoms that its displaying seem to line up with that theory.. either way I'm going to do exactly what you recommended and hopefully that will send me in the right direction and allow me to finally fix this issue once and for all cuz the car's been sidelined out of commission for a couple weeks now ..what a headache.. although I'm grateful it isn't something much more serious like I originally suspected..again thank you for your input and suggestions !!
