My truck has not been herself after a HG replacement last year. Like a Land Cruiser should, it still fires up each time, and plugs along like champ. I know how this engine feels when its happy, and it is not there yet.
I wanted to check the TPS sensor, since I am not certain if it was checked after the reinstall. I have the pages of the FSM printed off, and had my voltage meter and feeler gauge. I do not understand the results I am getting. When I put the leads together they read 0, unattached to anything they read ~380 ohms.
The reading between IDL-E2 @ 0.77mm is 430ohms which technically is less than 2.3kO, but the reading really doesn't change no matter where I move the throttle to. On the same terminals moving between no gap and fully open the readings only change from ~380-480ohms and only over a small range of the throttle moving. There are times when I move the clips/leads between the terminals and the meter doesn't change at all; which is strange since that makes me think there is nothing happening inside the TPS.
Basically changing between terminals and opening/closing the throttle really doesn't change much on the meter.
So, am I just messing this up? Can my TPS be this bad and I wouldn't really know? I get a crappy but consistent 10 mpgs, my truck is slow but I wouldn't necessarily say it sputters/hesitates/stalls. Usually the idle is pretty good, drops down to 600 rpms on occasion but is usually at the 650 mark and smooth. I just don't understand electrical properties enough to know if what I am doing is wrong or possible with a bad sensor. A little knowledge/wisdom would be greatly appreciated.
