TPS installation and location

The TPS is on the intake. Here is a picture of it:

1.Disconnect the negative battery cable. 2.Remove the air cleaner outlet pipe. 3.For 2006-07, remove the bolts and position the heated positive crankcase ventilation (PCV) fitting and hoses aside. Remove and discard the O-ring seal. 4.Disconnect the Throttle Position (TP) sensor electrical connector. Warning: Failure to remove the TP sensor screws in the following manner will result in damage to the screws. 5.First, loosen the screws 1-2 full turns using a hand tool, and then use a suitable high speed driver to complete the removal. 6.Remove and discard the 2 screws and the TP sensor. To install: Caution: Do not reuse the TP sensor and screws. A new TP sensor and screws must be installed. Warning: Do not use a high speed driver to install the new screws or damage to the TP sensor can occur. 1.Position the new TP sensor and install the 2 new screws. Make sure that the radial locator tab on the TP sensor is aligned with the radial locator hole on the throttle body. 2.Tighten the sensor screws to 27 inch lbs. (3 Nm). 3.Connect the TP sensor electrical connector. 4.If equipped, install the heated PCV fitting and hoses to original locations, using new O-ring seal. 5.Install the air cleaner outlet pipe. 6.Connect the battery ground cable.

I have two questions. when reinstalling do you have it at an 45 degree and rotate it clockwise or just put it on? The other I have I think this might be the cause of my problem. sometimes the truck will idle around 1000-1500 and other time normal. I have cleaned the MAS and the IAC valve is clean throttle body looks good i have a 2002 Ford Explorer six cylinder. Thanks

Engine Performance problem
2000 Ford Explorer 6 cyl Four Wheel Drive Automatic 97.000 miles

While driving at about 50-60 mph and all the sudden i have to stop pressing the gas pedal because of traffic matter, the rpm drops suddenly from , lets say 2.500 to 1.000 go back a little and then down.By the time that i have to accelerate again it takes like a second to respond like it should.Does the throttle position sensor anything to do with that?Thanks!!!

Yes, the TPS can cause that. Has the check engine light come on? Also, does it do this at an idle? It could also have to do with the idle air control valve or a vacuum leak.

Let me know.

I have a 94 Explorer Sport 4.0L V6 with 230.000 miles, Engine light comes on at freeway speeds, I get derrated power, then it goes away. I bought a code scanner and got a 538 code which is the throttle position sensor. Where is this sensor? Is this something that an above average shade tree mechanic can handle? Thanks!

the throttle position sensor or TPS is located on the throttle body, i would suggest you take it in to have it replaced.

it will usually have to go through a relearn and recalibrate as if it is off by a few thousands of an inch your TPS will not function properly.
