WTF? throtle switch?
« on: Jan 10, 2005, 11:58PM »
I was looking through my engine, in preporation to change over a wiring loom and i discovered the engine has an electronic throtle switch... but only on the old loom not on the new.
Is it only Auto's that have these switches? and can i leave it unplugged for my manual without any consequences? (there is no plug for it on my manual loom)

I think you mean the tps (throttle position sensor/switch)

There are 2 types on nissans. Usually a small black box on the side of the throttle body with 2 3-pin plugs on it. One is a switch to tell it then its at full throttle or idle, and the other is a constantly variable resistor, to tell the ecu how much accelerator is being used.

If your new loom does not have it and your running the de ecu, then dont worry about it :)

Yeah i got the plug for one of them, but not the other.  I was just interested in why one engine would have it and the other wouldnt?  ??? but if it doesnt make too much difference then we are set  :)

If the new ecu and loom only has one plug then dont worry. I would say that it is probably the variable plug so it can use it for load sensing.

personal experience i have had the TPS disconnected for a few months on a manual, i think it leads to worse economy
