Hey guys 99 dakota 4wd. i am trying to locate the excelerator sensor I can't seem to find it my book. Does anyone know where it is.

 

You can't find it because there is no such thing.

There is a Speed Sensor which tells your PCM how fast your going and translates it to MPH for your speedometer.
There is also a Throttle Position Sensor that tells your PCM what position the throttle plate is in.

What is the problem your experiencing?

 

when i am going up hills i step on gas and it seems like there is no power. I take my foot of the gas pedal then back on and it fine for while.

i have replace the throttle position sensor cause i thought that was it. strange thing is it never done all winter seems like once the warm weather came that's when it start.

 

If it helps I have a 98 and had a similar problem a while back. Of course there are many possibilities but in my case it was the crankshaft position sensor which is back on the bell housing on passenger side. Have to remove inner fender well. Should eventually get a "check engine" light.

 

It come on then go's off after the truck sits for while. i kinda had a feeling it was that. but i have to checkthe check engine light and see what code it is.
