How to replace a throttle position sensor on a 2000 ford contour

Hey DonAld, these are not hard to replace..( I do not know which engine you makes a difference!! ).. take a PICTURE of where the current TPS os positioned and located... the radial (adjustment) location IS critical!!..
here is a link to Autozone, ...O'Reilly's, and Advance Auto should have one too..

Why would throttle position sensor need to be replaced multiple times?

Sounds like the Voltage to the TPS is to high, burning them out to soon, unfortunately the only thing I can think of is a FULL COMPUTER DIAGNOSTIC !!

High idle on 86 Ford Bronco II (2.9L). Have replaced IAC, TPS and ECT. Also checked all vacuum lines. No fix. Need help.

I have heard of coolant sensors staying cold and keeping idle high but not a particular model.

1995 Ford Thunderbird, 4.6L. Fuel is pouring into the engine. All spark plugs show black soot. Checked Fuel Pressure and the regulator seems to be working. Exhaust smells like raw gasoline and raw fuel...

Hi, the primary sensor inputs used by the computer to establish the appropriate injector pulse width are the MAF snesor and the TPS. I recommend you test these sensors according to procedure pasted below and repair as indicated by test results. Please let me know if you have any questions, and thanks for using FixYa.

MAF Sensor Tests, 1995-96 4.6L Engines


Fig. Fig. 3: The mass air flow (MAF) sensor connector-1995-96 4.6L and 1996 3.8L engines

  1. With engine running, use DVOM to verify there is at least 10.5 volts between terminals A and B of the MAF sensor connector. This indicates the power input to the sensor is okay.
  2. With engine running, use DVOM to measure voltage between MAF sensor connector terminals C and D. If the reading is about 0.34-1.96 volts at idle, the sensor is okay.

TPS TESTING (Note, this procedure calls for a breakout box, but the same test can be accomplished by probing the back of the TPS connector at the brown/white and grey/white wires)

  1. Disconnect the negative battery cable.
  2. Remove the PCM and connect a breakout box to the PCM and harness.
  3. Probe terminals 89 and 90 with an ohmmeter.
  4. Slowly rotate the throttle shaft and monitor the ohmmeter for a continuous change in resistance. Any sudden changes in resistance indicates an open or substrate sensor.
  5. Reconnect the negative battery cable.
  6. Turn the ignition switch ON and using a voltmeter, measure the voltage between terminals 89 and 90 of the breakout box. The specification is 0.8 volts on the 2.3L, 3.8L and 5.0L engines or 0.9 volts on the 4.6L engine.
  7. If the voltage is outside the standard value or if it does not change smoothly, inspect the circuit wiring and/or replace the throttle position sensor.

I need to locate the throttle position sensor in a 1998 ford taurus

The location of TPS is to the left air filter / intake duct which attaches to the throttle body.You will see a small rectangular black box ON the throttle body with a couple of wires coming out of it. That is throttle position sensor (TPS). -------This will help.thanks.Helpmech.

I have a 07 gmc sierra on machine it said tps/ pedal position sensor A. Any info

This is indicating that the TPS Sensor is either out of calibration or defective however it sends dc low voltage to the computer like at idle it is reading its lowest value and when you tag the pedal(WOT wide open throttle) pedal to the will read its highest just to let the computer know if you are idling, driving slow or really stepping on it, these various TPS readings gives the computer the proper information to allow the different sensors such as the O2 sensor etc. and the injectors how to behalve through electronic voltage signals all the while keeping your vehicles engine running at its top performance for efficientcy and for clean exhaust emmisions.
The shop scanners are the best to use when replacing or resetting the TPS as with the proper testing for any other electronic sensors on your vehicle, these scanners are a bit too expensive for any one to be owning working on their vehicles, it just doesn't seem to be cost effective.
I think you would be better served letting a certified tech take care of this matter for you.
Hopes this helps

Reset throttle position sensor on 87 ford ranger

Ok in the Haynes Repair Manual it say that the TPS sensor is non adjustable on a ranger. Now if you have an adjustable one you have a TPS block that you use to set this sensor. The best bet is to line up the slot in the TPS with the blade on the throttle shart.
