Both do. Most likely you have an electronic throttle. So the TPS is located under the dash, connected to the gas pedal. Have the codes read. If it is either . first I would unplug them and plug them back in. (bad connection) check fuses. And then go after the part. If you're good with an ohm/volt meter, let me know. Then I can go more in depth for what to check. You will need a wiring diagram also.

I have 1995 Chev S10 with a 2.2L. It stubles from stop bad. I have replaced fuel filters and tuned it up,no help.


Test the tps using procedure below.


Throttle Position Sensor (TPS)
The Throttle Position Sensor (TPS) is connected to the throttle shaft on the throttle body. It is a potentiometer with one end connected to 5 volts from the VCM and the other to ground. A third wire is connected to the VCM to measure the voltage from the TPS. As the throttle valve angle is changed (accelerator pedal moved), the output of the TPS also changes. At a closed throttle position, the output of the TPS is low (approximately 0.5 volts). As the throttle valve opens, the output increases so that, at wide-open throttle, the output voltage should be approximately 4.5 volts. By monitoring the output voltage from the TPS, the VCM can determine fuel delivery based on throttle valve angle (driver demand).

TESTING


See Figures 1, 2 and 3

Backprobe with a high impedance voltmeter at TPS ground terminal and 5 volt reference signal terminal.
With the key ON and engine off, the voltmeter reading should be approximately 5.0 volts.
If the voltage is not as specified, either the wiring to the TPS or the VCM may be faulty. Correct any wiring or VCM faults before continuing test.
Backprobe with a high impedance voltmeter at the TP signal terminal and the sensor ground terminal.
With the key ON and engine off and the throttle closed, the TPS voltage should be approximately 0.5-1.2 volts.
Verify that the TPS voltage increases or decreases smoothly as the throttle is opened or closed. Make sure to open and close the throttle very slowly in order to detect any abnormalities in the TPS voltage reading.
If the sensor voltage is not as specified, replace the sensor.

My name Ilsur, I of Tatarstan , I have a jeep Grand cherokee WJ laredo 1999 4.0 error P0123 I replaced TPS but nothing helps, replaced the clockspring does not help, help me please


i had the same car.... what mileage.... 200K?
TPS errors. (its real its a real measured error)
this error is catastrophic, , meaning, not just a tad off,
the FSM covers this in details.
clock spring, the Air bag clock spring? has nothing to do with this.
or do you meant the throttle return spring, (my guess?)
the TPS output pin was discovered to have an illegal high voltage
on the output (you can be sure it idid)
spec:
TP Sensor indicated more than 4.50v for 700 ms.

caused by a bad TPS ground wire, or the output pin cut.
or the TPS internals are cracked in half (bad inside) (i have photos)
its bad TPS or bad wires to it. simple huh?
it will not be a bad ECU. as is on the list; it will not.
The jeep has great cheap TPS to buy ofter market,
on other cars not, and can cost $300 , for them
i connect my potable scope and watch the TPS output while i drive.
and find out if it is really truly bad.... hell the part, costs more than my
scope.!
be happy its not new car with throttle by wire, !!!
or the big V8 , whole new throttle body for $1000

recap. bad TPS, bad wires.

the tps on most cars are calibrated.
if you just thrown on a new TPS and not calibrate it, that is
a big failure.
here are the steps
1 key off
2 remove TPS.
3: put back new.
4:
The TPS is mounted to the throttle body. The throttle shaft end of throttle body slides into a socket in the TPS. The TPS must be installed so that it can be rotated a few degrees. (If sensor will not rotate, install sensor with throttle shaft on other side of socket tangs). The TPS will be under slight tension when rotated.
  1. Install TPS and retaining screws.
  2. Tighten screws to 7 Nm (60 inch lbs.) torque.
  3. Connect TPS electrical connector to TPS.
  4. Manually operate throttle (by hand) to check for any TPS binding before starting engine.

adjust the TPS for
0.26 volts at minimum throttle opening (idle)

worst case:
the FSM says it auto calibates
if the new TPS errors,. set it to 1/4 volt at idle.
reset ECU , all DCTs using scan tool
pull battery for 5min neg. lug (backup radio codes first)
put back lug
start engine, drive 25miles or till CEL comes on (failures)

Stability track


This is a common problem with GM's. The TPS sensor goes bad in the throttle body. Throws out a message to service Stabilitrac. Not SO!!!
The kicker is that the whole throttle body has to be replaced because the TPS sensor is actually part of the throttle body!!! Costs around $250.00 for aftermarket.

Where is the thorttleposition sensor on 2001jeep cherokee


The 3 wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the throttle blade.
The TPS is a 3wire variable resistor that provides the Powertrain Control Module (PCM) with an input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance (output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from .26 volts at minimum throttle opening (idle), to 4.49 volts at wide-open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to assist in performing the following calculations:

Where is the throttle positions sensor located


The Throttle Position Sensor, or TPS is connected to the throttle shaft on the throttle body.

zjlimited_2070.jpg

Fig. 2: Disengage the Throttle Position Sensor (TPS) wiring harness connector

According with the Grand Cherokee Repair Manual, check this removal & installation procedure...
(see Figures 5 and 6)
  1. Remove the air intake tube at the throttle body.
  2. Disengage the TPS wiring connector and remove the two mounting screws.
  3. Carefully remove the TPS from the throttle body.
To install:
  1. The throttle shaft end has a tang that can be fitted into the TPS two different ways. Only one of the installed positions is correct. When correctly positioned, the TPS can be rotated a few degrees. To determine correct positioning, place the TPS onto the throttle body with the throttle shaft tang on one side of the TPS socket. Verify that the TPS can be rotated. If the TPS cannot be rotated, place the TPS on the throttle body with the throttle shaft tang on the other side.
  2. Tighten the two TPS mounting bolts to 60 inch lbs. (7 Nm) and engage the wiring connector.
  3. Manually operate the throttle and check for any binding.
  4. Install the air intake tube.

Where is TPS sensor location on engine of 2003 GMAC Yukon XL denali?


TPS is always on the side of the throttle body, attached to the butterfly/throttle blade. Remove the tube that goes from the air filter housing to the throttle body, it'll be directly across from the blade, usually a squarish box with 2 wires connected to it.

Throttle position sensor


Sounds like you have a vacuum leak somewhere on the engine. If the tps was bad, it would set a code and the check engine light would be on. Also, check your air tube that goes to your throttle body - make sure the hoses are connected tight and the tps is on the throttle body down on the front of your engine where the hose runs down to it. It's not really that hard to get the throttle body off. That would be the best way to change the tps - to take the whole throttle body off and put new gaskets on and tps on it. Hope this helps you out. PHil
