1991 Toyota Camry running rich after cleaning the throttle body and replaced the throttle positioning sensor. Checked for vacumm leaks but cant find any

SOURCE: 1993 Toyota Camry IAC cleaning

1) remove the black intake hose from the throttle body
2) get a can of throttle body/intake cleaner
3) be VERY careful if you decide to use the straw included with the can of cleaner, it can detach and go inside of your intake manifold.
4) spray inside and use a rag to remove junk from throttle plate(front and back side), hold the straw on the cleaner can and spray into the hole just ahead of the throttle plate, let soak for 10 minutes or so
5) reattach intake hose and start engine - you may get black smoke/rough idle for a minute as junk exits the engine

fuel pump is working but when accelerating it doesnt pump enough fuel up to the engine then it will fall on its face if it is a electric pump you may have to drop the tank if it is inside and replace it if it is on the engine replace it thats what is exactly wrong with it

SOURCE: My 2001 Toyota Camry will not accelerate. The

i would not just go buy a tps on a guess
first check to see if you can bring the throttle up by hand at the motor where the throttle cable connects to the throttle body it may be a cable that broke

Testimonial: "Yes it does move and appears to be ok."

SOURCE: on a 04 camry with 2.4 ltr engine, can I replace

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!!

SOURCE: need to know location of throttle position sensor

Not 100% sure on your exact car but nissan TPS usually are on the opposite side of the TB from the butterfly return spring.
