TPS setting

[300freekzx]

How do you set the TPS when you place it back on the Throttle Body? I took it off my plenum when I cleaned the plenum and placed back but I do not think it is in spec. Please advise.

To check the throttle sensor (tps):Start the car.1) Disconnect the grey bottom harness connector2) Holding the grey connector from the sensor with the plastic connecting piece facing to the right, check the resistance between the middle terminal and the bottom terminal at the following accelerator conditions;Completely released - resistance should be approx. 1k OhmPartially depressed - resistance should be between 1k Ohm and 9 k OhmsFully depressed - resistance should be approx. 9k OhmsTo test the adjustment: Loosen the two bolts that hold the black portion of the tps to the throttle chamber. Set your multimeter to measure Volts and insert your leads from your multimeter into the harness while it's connected, where the black and white wires enter. You may need to stick a smaller wire (paper clip, misc. copper wire, etc.) into this area if your leads are too thick to be inserted themselves. Then while the car is idling, watch the voltage display and adjust the TPS by slightly rotating/moving the TPS unit up or down.

You want to get the voltage to read between .4V and .5V, with most people setting it at about .45V. When you get it to the proper voltage, simply tighten the bolts. Then unplug the grey connector for about 5 sec then plug back in. This will lower the idle to the proper level.

If you can't get the voltage to read between .4 and .5V you may need a new tps.

Hope this helps.

Add that after the TPS voltage is adjusted the ignition needs to be in the position just before start (all dash lights on) then unplug the gray connector for a few seconds then replug then turn off ignition then can start. Also use dielectric grease in the connector (and others as well) to prevent future corrosion issues.

As far as adjusting the voltage you need to do it with the gray connector plugged in and back probe the connector at the black and white wires. Use a digital voltmeter to set the 0.45 v.

Dumb Question but what V setting should it be set on? I have many on mine please help.

Depends on the labeling of your meter. Mine has a 2 volt scale so I use that. Some meters will lable the 2 volt scale as 2000m, m for millivolts. 1000m = 1 volt.
