HAD A PROBLEM WITH ENGINE LIGHT COMING ON, FOR 2001 SE TD 4JX1. WHEN TESTED AT LOCAL DEALER WAS TOLD IT WAS THE T.P.S SWITCH ON THROTTLE BODY.
AND WAS UP FOR WHOLE NEW ASSEMBLY, BIG $$$
BLOODY BUGGERS AT HOLDEN DEALER.

TPS is a Throttle Position Switch, mostly associated with throttle body fuel injected vehicles (petrol). But I am assuming the newish 4JX1 has a TPS due to the computer controlled Fuel injection system it employs. These vehicles are fly-by-wire (no accelerator cable) so they might now refer to a switch actually on the accelerator pedal.
Basically they are variable resister sender that informs the computer of your throttle position for fueling ratio information, be it for the throttle body or the throttle pedal!!
And being an electronic throttle, they tend to be jerky!!
Hope that helps, just glad I have a 4JG2, ahh simplicity!!!
Matt.
