LB7: Throttle Position Sensor Bad?

[WisconsinHick1]

I have had a few odd spikes and drops in my TPS graph while building boost for a sled pull. I have not heard too much about TPS going bad but I could imagine they do because it is an electronic.

What's the part number for them I would like to get one before it quites working on me.

Looooooong ago when my dad put one of the first PPE duramaximizers on his truck (now mine), he toasted a TPS sensor. dunno if it had anything to do with that or just a bad TPS but never had an issue since. So i could believe it going bad.

Check the wiring for your lockup box?

No lock up box on my truck just a tapshifter.

Your truck doesn't have a TPS, it uses an APPS. Basically the same thing, but for 01-05 trucks it has 3 TPS sensors inside it(06-10 is 2 sides). You need to log all 3 APPS outputs and look for variations in them. Also don't rule out poor connections. You have the plug at the APPS(throttle pedal), and that is part of about a 2' long harness that goes up to a firewall mounted connector under the hood close to the master cylinder IIRC.
