Read thru all the threads on the TPS having a little bit of trouble still. The wiring harness got pulled out and I m attempting to reattach. The wires coming from the ECU side are brown, black and green. Which is the ground, the reference voltage and signal input? I m measuring voltages on the ECU side but they don’t seem right. Voltage output that is high (10 to 11 volts) on the black and green wire and O volts on brown. Hopefully not a short in there somewhere. Second what is the pin out on the TPS itself? TPS on the throttle body itself top pin to bottom pin? Is it reference voltage on top pin, ground on center pin signal output on the bottom pin? Finishing up a lot of work on the van so I m down to the TPS and timing. Assuming I probably need to replace the TPS regardless.

Thank you
