I am told I need to repalce the entire throttle body on my 2005 toyota sienna. They said that the throttle position sensor can't just be replaced becasue of "fly by wire" technology. Is this true?

I would get a second opinion try NAPA or AutoZone and ask for the price of the throttle position sensor because on most cars you can get them without replacing the whole throttle body

Why won't my 2002 Toyota Sienna idle on it's own? I have replaced the Throttle Positioning Sensor already.


Clean the IAC motor and inside the throttle body. This will fix your problem.

Engine light on Toyota sienna 1999 system too lean code 171


On the inlet flex hose coming from the Air Filter to the Throttle Body, there is attached with 2 tiny screws the AIR FLOW METER,or by the side of the Throttle body,remove it carefully and remove the "O" Rings and use a carburator cleaner and clean the inside of it where the Hot-Wire is as the dust picked up by the filter will seat on the Hot wire and cause the false message sent to the ECU and makes car goes very slowly .

Location of throttle position sensor and how to replace it 1997 toyota camry 2.2 4cylinder


Hello

At the point where the air intake hose is connected to the engine is a part called the "throttle body". the TPS is attached to the outside of the throttle body. See picture below.

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!!
