Rb20det Fault Code #43 Tps Error Help!

[Ruffels]

Ok, Ive just put an Rb20det into my S12 Gazelle

and all the wiring is complete... came to start up time the other night and it idles nicely!

however will not rev!

plugged the computer into the consult port and get an Error Code #43 tps (throttle position sensor)

now i have put a forward facing plenum on the rb20det so i had to extend the wires for the tps (both plugs)

theres a plug with 2 wires going into it

and theres a plug with 3 wires going into it, both for the tps

anyways the computer is telling me there is 0 volts registering on the tps, and when i open the throttle it doesnt change.

however i believe i have extended the wires correctly...

so i got out my multimeter .. pulled the plugs off and tested it... the 3 wire plug gave me 5.12V incomming from the loom with ignition on

and the 2 wire plug gave me 11.96V incomming from the loom with ignition on

are these values correct? if so does this mean my tps is stuffed? and why is the computer reading 0 volts when my multimeter is reading 11.96v and 5.12v?

could really do with some help guys... thanks

The 5v is the power feed ot the tps. You need to measure the voltage at the other two wires in the three pin plug, ome should be 0v(earth) and the other should be the signal, 0-5v depending on the throttle position. The 12v is an idle switch.
