Adjusting TPS?

[SHODOGG]

How do I adjust the TPS Sensor on my car? I replaced it but at the time, I didn't realize that it needed to be adjusted so it def. needs to be done. How is it done and exactly what tools do I need?

what about it needs to be adjusted? you really shouldn't have to adjust the sensor. if your throttle response is really lagging you may need to adjust your accelerator cable, but the sensor shouldn't really need anything....that is unless i missed some good mod in the 6 months i haven't been on the board....which is possible... shoot us a little more info on your problem and maybe we can help you out.

Backprobe the center wire. It should measure as close to 1.0 VDC as possible without going over at KOEO or at idle.

It is usually necessary to wallow out the mounting screw holes in order to obtain any adjustment range.

This is a popular adjustment/mod from the Mustang crowd. Supposedly, it is should help with throttle tip-in.

I just installed and set the voltage on a TPS on my own car last night. You'll need a voltmeter with the negative probe attached to a chassis ground and the positive probe attached to a paper clip that is inserted into the center of the three electrical wires of the connector.

Leave the mounting screws loose so that the sensor can be moved around the slots in the screw holes. There is sufficient adjustment available so that no modifications need to be done to the sensor. It doesn't take much motion to adjust the output through a range of about .1 volt.

Start the engine and let it idle so that the operating voltage is maintained (higher voltage than the battery with the engine not running). Check the voltage on the meter. You should adjust the sensor's position so that the indicated voltage is approximately .95-.97 volts. When obtained, snug the screws and verify that the output voltage has not changed.

Now reset the idle speed settings by the idle speed reset procedure. I found that the throttle tip-in with the new sensor had corrected the dead spot just off idle that the old sensor had developed. My shifting is smoother as a result.

My local O'Reilly Auto Parts store also provides a lifetime warranty with the $23.99 Borg-Warner EC3019 sensor. I love those lifetime warranties.

so there is a noticeable gain to be had with this or did you guys do it because you had idling problems?

Throttle response is greatly improved (provided that it wasnt near the optimum setting initially)

BTW:

A digital multimeter helps wink

A LOT

I never got my TPS back from having the TB bored by Nook...can any of you guys tell me what size screws those are that go into the TPS? I have a new TPS I bought but no screws.
