Sometimes these codes are correct about the problem and sometimes they aren't, I ould suggest getting a service manual for a 2004 Camry and following the directions in it to find out for sure. Service manuals are helpful and have helped me fix problems before.

    if they have a pull-a-part junk yard in your area might get part reasonable price. Log onto internet to find nearest one, there is one in knoxville, tn. but more are around the united states

  • sherman north Nov 28, 2013

    you will have to remove the part yourself at pull-a-part junk yard

How to replace the throttle body sensor in camry 1994.

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)? ( 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>
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)
  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.

then ask questions about it. like 1MZ-FE.
or?? shows 6 engines.
and i can tell you they are not the same. not at all.
all diffr. EFI too.

04 Dodge Ram 2500 5.9 Cummins Loss of throttle, truck still runs happens intermittenlty Codes P2122 , P2121 and P2509

I do not have Cummins codes so I would consider replacing the injectors or taking it to a Cummins service centre to have it fixed as the parts will not be cheap if not diagnosed correctly

I have a 2004 Dodge Ram 3500 why do codes p0483,0541,0243,2121,2127 keep coming up what do these codes keep coming up

To get the meanings of these codes go to
P2121 - Check with dealer on this code
P2127 - Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage
P0483 - Cooling Fan Rationality Check Malfunction
P0243 - Turbocharger Wategate Solenoid 1
P0541 - Air Intake Heater Circuit Low
If you are located near a National Auto Parts store (AutoZone, Pep Boys, etc.) I would take the truck in and have them run diagnostics.
Let me know if you have any other questions. Thanks.

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!!
