Installing throttle positioning sensor

I need to know what to take off to get to the two screws holding in the TPS. It seems to be impossible to get to the back screw. I see two bolts for the pedal assembly, but wanted your advice first. Thanks

    look u do what ever it takes to get to the screw, most likely that means removing the throttle valve assembly, that is what I do.

There are specialty tools that make removal a little easier, flex shafts. angle drive drivers...etc.
Not sure why you need to replace the TPS on the 3.2, but if it's for a trouble code repair this is rarely the problem.
Good luck...i hope this helps.

Where's the idle screw on a 2002 Cadillac Deville


No screw - fully computer controlled. Also, there is no idle control sensor - just a throttle position sensor (TPS) and an idle air control (IAC) motor. If you are replacing the IAC, clean the throttle body ports VERY carefully using a recommended solvent.

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.

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:

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

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.

Additionally, its possible that you are interesting in some section about this repair manual: Jeep Grand Cherokee 1993-1998 (ZJ Series).

Hope this helps; just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment. Thank you for using FixYa.

1990 lincoln continental throttle stuck wide open


make sure nothing is caught holding the plate open,disconnect the throttle cable from the throttle valve at the intake.if the throttle closes then i would say you have a problem with the cable itself and will need to be replaced.make sure there is nothing caught at the gas pedal that is holding open.if the throttle stays open then you may have a problem with the throttle shaft(dirt build up),bent shaft,damaged throttle plate,loose plate(has screws holding plate in position)on the shaft.it could also be a bad tps sensor(throttle position sensor)that is damaged internally and needs replacing,as it is fasten to the opposite of the throttle shaft from the cable.if you remove the screws(note position of sensor and screws on sensor)and remove the tps and the throttle is not stuck then this is probably the problem and needs replacing.

How do I replace my throttle position sensor on a 2003 bonneville ssei


Hi, The tps is located on the side of the throttle body. Disconnect the wiring connector and then the two mounting screws. You may need to wiggle the tps a little to free it from the throttle body. Installing is just the reverse and there is no adjustment for these. Good Luck

Need to know where the throttle body positon sensor is located?


The tps is usually on the side of the throttle body, some have a black plastic casing, just 2 screws hold on. Don't mistake it for the iac (idle air control) valve.
