Had some extra time so I checked my TPS voltage. With the meter hooked as described I got nothing. When I reversed the leads I got -.92. Is there something I'm missing? If I get -.92 one way when I reverse the other way I should read .92 correct?
Thanks

i think its suppose to be .98 - .99

 

I agree. I'm maxxed out on adjustment. The question is why am I reading a negative .92 when I reverse the leads.

If you swap the leads around, you will get a negative reading.
On your first try, you probably weren't making a good connection. Try it again.
Also, make sure the voltmeter you are using is set up properly. If the leads are removable, it may have the red lead in the negative and the black in the positive.
Before you jump to conclusions, take a deep breath and start again, checking everything (inc the meter) over.

 

Deep breath taken and I still get the same readings. Open circuit reading it properly and reversing the leads give me a -.92. On the meter all is hooked up properly.(red to red etc). If I get a -.92 one way if I reverse the leads should I get +.92?

What's the range on the meter set on?

 

Sounds like either you aren't making a good connection the one way, or your meter may be bad.

 

See if the fuse in the meter is blown...this has happened to me a few times.

 

Meter is an automatic digital fluke. If it reads one way should it not read the other? It has to have a good connection on both regardless of which way you read in order to get a reading at all. Maybe my TPS is bad. I'm pretty good with electrical troubleshooting (aircraft mech) but who knows how these things are wired. I don't have a schematic.

If the meter is reading one way and not the other it is not the TPS or the truck, it is the meter. The laws of physics dictate that if you have negative voltage one way you are going to have positive voltage the other way. Are you sure you don't have the meter set on a transistor or diode check or something other than DC Volts?

 

Meter is a fluke fully automatic. only has an on/off switch. I put the meter on the battery posts and read positive voltage one way and negative the other. Kinda rules out the meter being faulty.

Does your meter read - and + voltage across the battery? If not it's likely a meter or connection problem.
