tps sensor

[minytrker]

I have a 99 camaro with typical bolt ons and a cam. On the street the car works fine 99.99% of the time. The two times I took it to the track on the launch the car will flag the tps sensor and then the car nose dives down. I have put three tps sensor's in, did the tps reset, check the volts, check the range of the tps, everything is always perfect. Every now and then, like 2 or 3 times in the last 2 months it will flag the tps when you start the car. The weirdest thing is how it will work on the street, but at the track it wont. I am open for any idea's.

Thinking Out Loud (TOL):
when launching, the g-force is probably moving the wires and/or harness around, intermittently exposing a break or short or something, something that will drive you nuts.

I think your right, yesterday when we had the scan tool hooked up I shook the harness trying to see if the voltage would change, it never did. But since then I have now made 18 passes.
