TPS wiring?
« on: April 21, 2014, 10:21:43 AM »
I currently have a suspected wiring issue with my TPS. My question is, am I able to run a new signal wire directly from the tps, through the engine bay to the ecu, bypassing the engine loom? Or will this cause another problem?

Cheers!

There is a short in the voltage and signal wiring, which I believe is sending the 5v power straight into the signal wire, showing WOT regardless of throttle position.

so when you test from signal to ground there is +5v with tps not plugged in? signal is center cable on the sepperate plug on a little lead.

unplug the computer and test on ohms across the 3 cables should all be open circuit

just check the throttle stop is not wound out too far will cause you to have less range on the tps. that other plug is like a kick down cable for an auto but electronic from memory. make sure you test and set it with car running as value will change slightly depending on what your battery voltage is running / not running.

Now that that is sorted, and I have no error codes, that must mean the electronics are good for the dyno! Now to check for boost leaks and we should be close!
