SOURCE: Doesn't stay running

Their is a few ways to test the throttle position sensor. One way is to hook up a scaner and go to the data menu. Their will be a place in the menu that will say tps % and tps v. You want to watch the one with the v. The v stands for volts from the t.p.s. Basicly the t.p.s. is a variable resistor. The further you depress the the throttle the more or less volts you get from the t.p.s. The voltage should gradualy go up as you slowly depress the pedal. If the voltage jumps around then the t.p.s. is bad. Another way is to get a volt meter and remove the connector to sensor, touch the contacts on the sensor with the sensor still hooked up and have a friend depress the pedal slowly.

You can find the tps on the opposite side of the cable on the throttle.

Please contact me if you have any more questions or comments.

Thanks, Charlie

SOURCE: tests for throttle position sensor

Hi
You can test the sensor with an ohm meter . Unplug the conecter from the sensor . There are three connecter pins . The top being one and the bottom three.

With the meter leads accross terminals 1 and 2 and the pedal at idle position the meter should read 20 ohms .
At wide open position it should read 6000 ohms .

Then put leads accross terminals 2 and 3 .
At idle position meter shouls read 0
at wide open should read 4600 ohm,

Well the TPS would probably not keep it from starting, just not accelerating.
You would check the sensor with a meter for resistance.

SOURCE: throttle body

Check the connections, you probably have an issue there. maybe a bent or broken pin. Also, why did you replace it in the first place - did you already have a problem?

Testimonial: "Well my wife took it in and had the check engine light tested because when on the freeway the car would jerk constantly then the test read that the throttle body sensor was faulty so I switched it out then all of a sudden the idol would fluctuate on its own"

Po 122 problem light on had changed sensor problem not fixed trans not shifting right horrible jurks when it shifts.


P0122 is TPS signal low, which could mean you have a bad TPS, or a fault in the wiring or connector. I suspect a bad Throttle Position Sensor.

Wat does the throttle position sensor do


throttle position sensor its a sensor that reads where the throttle pedal are to give the car "brain" the information about how much gas+air mixture need to be used.

Throttle position sensor


You should test it before replacing, just to make sure there isn't another problem you are missing. The computer only knows something isn't right.
I would do the testing before removal, as the tps is integrated with the throttle actuation motor. Remove the connector from the sensor and use an ohmmeter to check the sensor. Inspect the connector and pins carefully for damage. Also inspect the wires carefully. If visual inspection looks good, move on to testing. The sensor circuit includes three pins in the connector--pins B, D, and H in the lower left of the diagram below. Remove the rubber air pipe from the throttle so you can open the throttle by hand. Then connect your ohmmeter to pins H and D. Then slowly open the throttle by hand. The resistance between the pins should change continuously and linearly as you open the throttle by hand. If that test is good, move the ohmmeter probes to pins B and D and run the same test. If the sensor fails these tests, replace the whole integrated throttle control assembly. If it passes, the problem is probably with the connector or wiring.


The link below includes the procedure to remove the sensor.

My Hyundai Santa Fe 2004 doesn't shift down from overdrive when driving at 70 mph. Recently replaced the crankshaft sensor and timing belt. It is an automatic and the other gears seem to shift alright....


You might try testing the tps. It may have a dead spot at the high end of the throttle opening. Make sure the resistance continues to change as you open the throttle all the way.

Throttle Position Sensor

Operation The throttle position sensor is a rotating type variable resistor that rotates with the throttle body-s throttle shaft to sense the throttle valve angle. As the throttle shaft rotates, the throttle angle of the sensor changes and the ECM/PCM detects the throttle valve opening based on the TPS output voltage.
Removal & Installation
  1. Disconnect the negative battery cable.
  2. Disconnect the sensor connector.
  3. Remove the sensor retaining screws. Remove the sensor from its mounting.
To install:
  1. Installation is the reverse of the removal procedure.
Testing 2.4L Engine
  1. Disconnect the sensor connector.
  2. Measure the resistance between terminal 1 (sensor ground) and terminal 2 (sensor power).
  3. Specification should be 3.5-6.5 kohm.
  4. Connect and analog ohmmeter between terminal 1 (sensor ground) and terminal 3 (sensor output).
  5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
  6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.
2.7L Engine
  1. Disconnect the sensor connector.
  2. Measure the resistance between terminal 2 (sensor ground) and terminal 1 (sensor power).
  3. Specification should be 3.5-6.5 kohm.
  4. Connect and analog ohmmeter between terminal 2 (sensor ground) and terminal 3 (sensor output).
  5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
  6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.
  1. Disconnect the sensor connector.
  2. Measure the resistance between terminal 2 (sensor ground) and terminal 1 (sensor power).
  3. Specification should be 1.6-2.4 kohm.
  4. Connect and analog ohmmeter between terminal 2 (sensor ground) and terminal 3 (sensor output).
  5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
  6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.
3.5L Engine
  1. Disconnect the sensor connector.
  2. Measure the resistance between terminal 3 (sensor ground) and terminal 1 (sensor power).
  3. Specification should be 3.5-6.5 kohm.
  4. Connect and analog ohmmeter between terminal 3 (sensor ground) and terminal 2 (sensor output).
  5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
  6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.
