I recommend you test the tps according to procedure below. Especially step 8. Suspect you will see drop outs in the voltage, which indicate sensor is worn out.
Operation

The Throttle Position Sensor (TPS) is mounted to the side of the throttle body and connects to the throttle blade shaft. The TPS is a variable resistor that provides the PCM with an input signal (voltage). The signal represents throttle blade position. As the position of the throttle blade changes, the resistance of the TPS changes.
The PCM supplies about 5 volts of DC current to the TPS. The TPS output voltage (input signal to the PCM) represents throttle blade position. The TPS output voltage to the PCM varies from about 0.5 volt at idle to a maximum of 4.0 volts at wide open throttle. The PCM uses the TPS input, and other sensor input, to determine current engine operating conditions. The PCM also adjusts fuel injector pulse width and ignition timing based on these inputs.
Testing

In order to perform a complete test of the TPS and related circuits, you must use a DRB or equivalent scan tool, and follow the manufacturers directions. To check the Throttle Position Sensor (TPS) only, proceed with the following tests.
  1. Visually check the connector, making sure it is attached properly and that all of the terminals are straight, tight and free of corrosion.
  2. The TPS can be tested using a digital ohmmeter. The center terminal of the sensor supplies the output voltage. The outer terminal with the violet/white wire is the 5-volt supply terminal and the black/light blue wire is the sensor ground terminal.
  3. Connect the DVOM between the center terminal and sensor ground.
  4. With the ignition key to the ON position and the engine OFF, check the output voltage at the center terminal wire of the connector.
  5. Check the output voltage at idle and at Wide Open Throttle (WOT):
  6. For 1996 vehicles at idle, the TPS output voltage should be greater than 0.35 volt (0.4 volt for the 2.4L engine). At WOT, the output voltage should be less than 4.5 volts (3.8 volts for the 2.4L engine).
  7. For 1997 and later vehicles at idle, the TPS output voltage should be about 0.38-1.20 volts. At WOT, the output voltage should be about 3.1-4.4 volts.
  8. The output voltage should gradually increase as the throttle plate moves slowly from idle to WOT.
  9. If voltage measures outside these values, replace the TPS.
  10. Before replacing the TPS, check for spread terminals and also inspect the PCM connections.

How can i tell if the thottle position sensor is bad without a multi meter and how do you adjust it when reinstalling


What make , model an year vehicle ? An engine size . Most TPS sensors are non adjustable . An you can't tell if it's bad without testing . Suggest you take your vehicle to a qualified repair shop that know how to test an replace a TPS , because i think your just guessing , looking for a magical fix .That's not how we repair automobiles .

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:

Ignition timing advance Fuel injection pulse-width Idle (learned value or minimum TPS) Off-idle (0.06 volt) Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage) Deceleration fuel lean out Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage) A/C WOT cutoff (certain automatic transmissions only)


Removal & Installation

3.7L & 4.0L

  1. Disconnect TPS electrical connector.
  2. Remove TPS mounting screws.
  3. Remove TPS.

To Install:
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.

4.7L
  1. Remove air duct and air resonator box at throttle body.
  2. Disconnect TPS electrical connector.
  3. Remove two TPS mounting bolts (screws).
  4. Remove TPS from throttle body.

To Install:
The throttle shaft end of throttle body slides into a socket in 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 two retaining bolts.
  2. Tighten bolts to 7 Nm (60 inch lbs.) torque.
  3. Manually operate throttle control lever by hand to check for any binding of TPS.
  4. Connect TPS electrical connector to TPS.
  5. Install air duct/air box to throttle body.

Hope this helps

Adjustable throttle position sensor


I'm assuming you have the 3.3l v-6. When I look up the part, it seems to have slotted holes. Therefore, it is designed to be adjusted after installation. If your tps has these slotted bolt holes, adjust it to satisfy the settings in the test procedure below.
  1. Remove air cleaner. Disconnect the TPS harness from the TPS.
  2. Using suitable jumper wires, connect a digital voltmeter J-29125-A or equivalent to the correct TPS terminals A and B.
  3. With the ignition ON and the engine running, The TPS voltage should be 0.3-1.0 volts at base idle to approximately 4.5 volts at wide open throttle.
  4. If the reading on the TPS is out of specification, check the minimum idle speed before replacing the TPS.
  5. If the voltage reading is correct, remove the voltmeter and jumper wires and reconnect the TPS connector to the sensor.
  6. Reinstall the air cleaner.

Getting the following codes from a 1997 Pontiac Grand Am....... PO121 TPS / Pedal Position Sensor A CKT Range / Perf Also, PO341 Camshaft Position Sensor A - Bank 1 CKT Range/Perf. Any thoughts on the


po121 means that there is a problem with the throttle position sensor ( tps). or in the wiring or connector, most likely its the tps that is bad. first remove connection from tps, heres how to test. use an ohms meter and hook a lead to top or bottom terminal of tps. use other probe on center terminal of tps. move throttle plate slowly, if the needle on meter does not move at a smooth pace, then tps is bad. good-luck!!
