Hi all,
I was trying to reset my TPS because I was getting code 24 [VSS], during slow [25mph] cruising. I had it set at .46, 4.78. However, with the ignition on, engine not running, when I was checking out full throttle readings the reading would suddenly jump down, sometimes as low as 2.5 volts, then back up to 4.7 or so, then down to 3.2 then back up. I removed the boost sensing harness, same problem. I cleaned all the connections, smae problem. I just wanted to make sure that it's not just because the engine wasn't running, and I'm figuring that the TPS has failed. IT's not the original TPS, but is a few years old. Unforttunately I can't find my old one to check that out. Is there any reason that turbolnk would read this way unless the TPS is bad? I was holding the throttle hard to the floor, not moving it in the least, and these jumps occurred. Also, once it dropped to .32 on closed throttle, but only once.
Tahnks, I'm sitting here with the hood up trying to decid what to do.

ok, well I went and bought a new TPS sensor, installed it, and got the same readings. Now that I have a spare TPS, I noticed that there were other strange readings while checking the full throttle TPS setting with the engine not running. The TCC flag would go on and off coincidentally with the drop in TPS voltage, as well as the 3rd gear flag, no rhyme or reason that I could see. I made a full throttle run out on the beltway, and every frame had 4.76 to 4.79 hammer down, no anomalies there. It's probably the oldest laptop that exists, a Bondwell Turbo [sic] running at 3.54 MHZ!, using dos 3.21, didn't have replaceable batteries, so it's plugged in to a little inverter, no hard drive, just 2 floppy drives. Maybe it's just the weenie computer rig I've got.

It also could be your inverter ... some of them are extremely "noisy", since they produce a sawtooth wave for the AC instead of the sinusoidal wave out of the wall socket.
Sometimes that feeds back down through the laptop and affects TurboLink...
