What is the procedure for said task? And what resistances shud i be reading between which terminals.... testing: the TPS is adjustable and you will need a mic to get it adjusted back to where it was (unless your TPS still has the paint dot on it from where they marked it when it was set) Use the below diagram as a guide to set it back to normal. Or you can look up more info here that might help.  Testing the TPS itself: If your car is 95 or older you can test the idle switch in the TPS by connecting TE1 and E1 in your diagnostic service port under the hood. If it is 96 or older you can plug in a scan tool with the function test (or a $20 ebay bluetooth OBD reader and the free Torque app in the Android market) and check the TPS sweep by slowly moving the gas pedal and watching the graph (or number value) raise with the pedal movement. extra info: Toyota TPS sensors are all wired the same, if they are a 4 pin connector. On one end of the 4 pins is a brown wire (ground[e2]), the opposite end of the brown ground wire is the TPS supply (5v[vcc]) the wire next to this is the TPS signal[VTA], and the one beside the brown wire is the idle switch[IDL]. (sorry, I don't remember the pin order, just where they are in reference to the brown wire). In order they are: E2, IDL, VTA, Vcc. Warning: The ecu uses the 0 - 5 volt signal generated between pins 2 and 3 as it opens and closes. DON'T measure the voltage level with the TPS harness connected, or the signals coming off of the ecu. Multimeters can potentially kill an ecu. -------------------- -Jay
