Connector has a release clip on it. Part itself is held on by two torx screws. Keep the new part straight and make sure it engages the throttle shaft when replacing it. There is no adjustment.

The governor pressure sensor is the most likley cause however an inspection of fluid or debris in trans pan would be a good idea to make sure there's nothing excessive in it. Attached is a list of possible causes however the senor would be the most common.

POSSIBLE CAUSES

  • Powertrain control module
  • 5 volt supply circuit open
  • Check transmission fluid level and condition
  • GOV press sensor signal circuit shorted to voltage
  • GOV press sensor signal circuit shorted to sensor ground
  • GOV press sensor signal circuit shorted to ground
  • GOV pressure sensor signal circuit open
  • Sensor ground circuit open
  • GOV press sensor signal circuit shorted to voltage inside transmission
  • 5 volt supply circuit open inside transmission
  • Intermittent governor pressure solenoid
  • Internal transmission problem
  • Oil burnt or oil pan has excessive debris
  • Other transmission DTC'S
  • GOV press sensor signal circuit shorted to sensor ground inside transmission
  • Valve body
  • GOV press sensor signal circuit shorted to ground inside transmission
  • GOV press sensor signal circuit open inside transmission
  • GOV press sensor ground circuit open inside transmission
  • Governor pressure sensor (high)

94 Jeep Cherokee TPS - back feed


You are still getting high or low voltage at tps? What is the voltage and do you have a unstable idle? Put you + lead on terminal 3 and - lead on terminal 1 turn ignition on and check voltage to be at approximately 5 volts. You can also back probe with it connected at center wire and ground probe to a good ground at engine. Turn ignition on it should read between 0.20 - 0.90 slowly manually open throttle it should rise all the way to 4.5 voltd at full open. If its bad change tps if no 5.0 volts from pcm on first test check connections at pcm. The center tps connector supply wire comes from pin 22 and connection 3 ( which is 5 volt supply ) comes from pin 6. You should be able to back probe pin 6 turn ignition on and have 5 volts. If not 5 v brain has problem.

How to replace the TPS.


no engine option stated, and is key fact to know here.
eg:
The 5.7L V8 engine does not use a separate Throttle Position Sensor (TPS) on the throttle body.

remove old TPS, and bolt on new.
its like 2 or 3 screws. no big deal.
but needs to be calibrated per fsm.
ill take a wild guess, 3.7L
3.7L Engine and 4.7.
  1. Remove air resonator tube at throttle body.
  2. Disconnect TPS electrical connector.
  3. Remove two TPS mounting screws.
  4. Remove TPS.
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 retaining screws.
  2. Tighten screws to 60 inch lbs. (7 Nm) torque.
  3. Connect TPS electrical connector to TPS.
  4. Manually operate throttle (by hand) to check for any TPS binding before starting engine.
  5. Install air cleaner tube to throttle body.
some TPS need calibration
to see what yours needs, read the FSM
or at alldata.com
or here. I think all engines here, are TPS PCM autocalibrated.

its 2 places.
The FSM (a book by that name from Jeep, by year,model)
and Alldata.com
Just the connector, the schematics dont show all pins and names.
only by function, say you have bad TPS input and you got TPS page
and see pins and colors on PCM.
the connector is in the book.
at the end of chapter 8w, page 80 are all connectors and page one is the index there. listing page 8w-28,29,30 for the 3 PCM conn.
see them here, in WIRING.
PDF page 178.
there.
see it?

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.
