Anyone ever taken readings and set the TPS switch with it still plugged in? Wondering if this would even work.... back probing the green and red wire with the positive lead from voltmeter, the neg lead grounding out on the neg battery terminal. Or... do you have to have the TPS disconnected? Also, if you find the wide band to be out of spec, how are you to adjust it since there is no adjustment screw for it on an S5?

 

Fully warmed up & key to on with car either running or not.

 

You can check the voltage with it plugged in, yes. The specs are in the FSM:



You should still check if the resistance is correct however.

 

And resistance needs to be checked with it unplugged with the key in the on position?

 

If the plug is disconnected then the ignition turned to on would have no affect on the sensor being tested. Say yes. Also, when checking for resistance on a circuit it would "always" be done with the power off! This prevents damage from being done to the components.

 

Why on God's green earth are you all OBSESSED with ohming out a TPS?

The end result of a properly rigged TPS is shown in the pages called CONTROL UNIT. If the narrow range meets the approx 1vdc rigged positon and the full range is APPROX 0.8 vdc.........then get on with your life and do something useful.

The FSM has a procedure for checking to see if the pot in the TPS is worth a bucket of warm spit and you should use one of those old analog or *swing* meters to do that procedure. That procedure is NOT for rigging the TPS. It's to diagnose a TPS to see if it has opens in its wiper/pot. Same thing could be done by looking at a meter set on volts dc and running the throttle thru its full range open/shut.

 

lol ^ your full of rage haha
