Hey guys, I'm testing my tps and am getting strange readings. When I back probe the plug I'm getting an initial reading of .4 volts. As I rotate the tps the voltage readings go into mv. If I rotate it all the way I max out at around 60 mv. I get this reading on two different sensors i've tried. Do I have the wrong sensor? I was told at napa that they have two different part numbers for this. One shaped like an "L" and the other one straight. I am at a complete loss and am looking for a second opinion.
