Hope this will help...
1. Locate the OBD data link connector (DLC). Refer to your owner’s manual for the specific location.
2. Turn your key to the “ON” position. Do not start the engine.
3. Plug your scan tool into the OBD data link connector. Turn on the scan tool and select the appropriate steps to read the diagnostic trouble code (DTC).
4. Locate the throttle position sensor.
5. Disconnect the electrical connector from the throttle position sensor.
6. Test the resistance of the throttle position sensor (TPS) with a digital multi-meter. If the resistance is out of specifications, the TPS must be replaced.
7. Remove the throttle position sensor.
8. Install the new throttle position sensor. Tighten the mounting screws and attach the electrical connector.
9. Erase the diagnostic trouble code (DTC) with the scan tool using the “delete” or “erase” command. Road test your vehicle to see if the check engine light returns.

Will a TPS begin to fail without throwing a code?

Recommended but optional step 0: purchase a stubby, magnetic JIS (#2 I believe) screwdriver. It's a tight fit back there and a Philips can 'cam out' and strip a stubborn screwhead.
The Vessel brand is usually Made in Japan so you don't have to buy cheap Chinese crap

Can also put a screwdriver bit in a 6.5mm socket (I think that's the size) and turn it using your socket wrench.
To add to the above answer, it can and will fail before throwing a code. I was getting odd spots where the engine would act like cruise control was on but it wasn't at around 70 MPH. It was driving itself for a few seconds. Then the RPM was wildly rising and falling at idle. Then came the stalling. I replaced the TPS at that point and fixed it all.

Tps?
01 SR5 limited V6 240xxx miles
If I’m beating a dead horse, I can’t find it….
My throttle response would die and get nothing going to the floor. Than it would pick back up again and be off and on a few times. Than it stops working all the way to 3/4 pedal to the floor and finally gives some response. The throttle response at that point is slow at 3/4 throttle. If the vehicle is off for an extended period of time it seems to just reset itself. But after driving for about 10-15mins it’s back to using 3/4 throttle and forward to get going.
I assumed it was the TPS but after installing a new one, it was completely as if it was never replaced.
I just installed a used throttle body with and it is complete with sensors. This one at first start was immediately 3/4 throttle gets my RPMS moving. Does the TPS or ECU need to be re programmed?
Again if it’s been discussed please point me to it as I have searched.

01-02 are not drive by wire. They are cable driven. The cruise control is controlled by wire. I think the part number for the Tps is the same as a 2000 4runner which is
89452-35020.
01-02 are drive by wire with a cable as a backup. They have a throttle pedal position sensor and a throttle actuator. Different throttle body so I would not be surprised if it's a different throttle position sensor part number.
EDIT: Poor wording on my part. See post #19 for clarification.

Unfortunately, they are throttle by wire and its throttle position sensor is way different then the earlier years. The cable is there as an emergency safety only.
The throttle bodys are totally different, then the 1996 -2000 and the sensor are as well.
I recall reading somewhere where you can't get the 01 and 02 tps sensor. But that part I could be wrong on. I do know they are nit the same though.

My understanding was that the gas pedal controls the input which then is taken over by the ecm so the cable is connected to the gas pedal.
2001 and 2002 Are NOT Drive By Wire
2001-2002 Throttle Body Design Question
I think this explains it best: https://www.toyota-4runner.org/2706298-post15.html
The throttle cable goes from the pedal to the throttle body, but it does not connect directly to the butterfly valve in the throttle body. Instead the throttle position sensor reads the position at the throttle body and tells the throttle body actuator where to move.

I get it. I am trying to find a thread where one of the members replaced the tps sensor on his 01-02 throttle body. Recalling the difference between the early years 3 pin and 01-02 being 4 pin.
