Which one, some have 2, one is TPS other is MAF.
post a photo with finger pointing?
TPS: (guess 1)
that is the first step in the FSM book made.....

on all cars. "disconnect the battery before replacing electrical parts."

the only danger here, is losing radio codes, and NAV on new cars.
some cars need to do a relearn steps. (FSM covers all this get one)? (alldata.com or at toyota or used off ebay>)

on many cars the TPS, its called, needs to be calibrated.
why hot read the FSM and follow the simple steps.
no engine stated so I can NOT be specific.
you dont know whats under the hood and you are fixing it>?

94 camry. V30 model.
ill try my dice. I roll and land on.
6 camry, and 2 engines, and i guess USA>
https://parts.olathetoyota.com/toyotaoemparts.html
i guess DX and 2.2Liter.

1994 is big time transition year, so...... need all that.
up to 8 engines used world wide, but not in USA. we had 2.
one is a V6, got that?

ill post FSM qoutes to prove my case (not like changing a light bulb)
1MZ-FE

  1. Loosen the sensor screws. Apply vacuum to the throttle opener, if equipped.
  2. Insert a 0.021 inch (0.054mm) feeler gauge between the throttle stop screw and lever.
  3. Connect an ohmmeter to terminals IDL and E2 of the sensor.
  4. Gradually turn the sensor clockwise until the ohmmeter deflects and then tighten the screws.
  5. Using a 0.014 inch (0.035mm) feeler gauge between the throttle stop and lever, verify with an ohmmeter that there is continuity.
  6. Using a 0.030 inch (0.070mm) feeler gauge between the throttle stop screw and lever, verify with an ohmmeter that there is not continuity.


5S-FE? got that?

The TPS set wrong will cause the following problems.
1: Cruise failure.
2: EFI IDLE controls dead.
3: automatic transmission, shifting issues.
and more.


FIRST DISCOVER ENGINE TRUE NAME ,
then ask questions about it. like 1MZ-FE.
or??

alldata.com shows 6 engines.
and i can tell you they are not the same. not at all.
all diffr. EFI too.

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.

L300 Saturn 2003 trying to replace my throtter sensor. Can't figure out where to start from. Have no idea where's it located.


Your vehicle has electronic throttle control an the Throttle position sensor's are internal to the throttle body assembly ! Your vehicle has two throttle position sensors .
Throttle Body Assembly
The throttle assembly contains the following components:
?€¢ The throttle blade ?€¢ The throttle actuator motor ?€¢ The throttle position (TP) sensor 1 and 2 You have to replace the Throttle Body Assembly !
Disconnect the negative battery cable. Remove the inlet hose assembly from the throttle body. Disconnect the throttle body electrical connection. Disconnect the hose clamps from the plenum-to-runner connector using theJ 43914 .
Remove the intake plenum bolts. Remove the EGR passage bolt. Rotate the plenum up and remove the throttle body coolant hoses, EVAP hose, and vacuum line from the throttle body.
Remove the throttle body nuts. Remove the throttle body.

Throttle position switch. how much for the part? is it easy to repllace?


This sensor sends the ECU an output signal which corresponds to the opening of the throttle valve. Using this output signal, the ECU precisely controls the air/fuel ratio during acceleration, deceleration and idling. The TP sensor and the throttle switch are combined as part of an assembly. The switch signal turns ON only when the throttle is opened to the idle position or at Wide Open Throttle (WOT) acceleration.

REMOVAL & INSTALLATION

Fig. 5: Lift off the throttle position sensor
  1. Disconnect the negative battery cable.
  2. Disconnect the throttle sensor electrical harness.
  3. Place a matchmark on the throttle position sensor and throttle body mounting surface, so that during installation, the sensor can be properly aligned.
  4. Remove the 2 screws securing the throttle sensor to the throttle body assembly.
  5. Remove the throttle sensor by pulling it in the axial direction of the throttle shaft.
  6. Remove the throttle sensor O-ring and discard.
To install:
  1. Using a new throttle O-ring, install the throttle sensor, aligning the matchmarks. Install and hand-tighten the retainer screw.
  2. Connect the throttle sensor electrical harness.
  3. Connect the negative battery cable.

2004 Toyota Camry keeps dying while driving but it starts right back up. Replaced fuel pump and air filter but it's still doing it. Someone said it may be the catallytic converter? Does that sound right?


You may have problem with your cooling system. Follow these simple steps to try to rectify the problem:

1. Write down the code of your radio.
2. Allow the engine to cool down. Disconnect the battery negative terminal.
3. Locate the ECT-engine coolant temperature sensor. It is located to the right of the engine head-cover, by the metal hook. The number two sensor with black wire connector. You will see the large coolant hose connecting to its body. That's the ECT.
4. Depress and pull out the wire plug.
5. Use a deep socket with wrench to remove the sensor.
6. Replace the ECT, reconnect the plug wire and the battery negative terminal.
7. Crank up the car again and test drive.

On a 04 camry with 2.4 ltr engine, can I replace just the throttle position sensor or do i have to replace the entire throttle body? The engine code said faulty throttle body.


I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.

My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.

The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!

Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.

So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!
