Throttle Body

[cashflow50]

Can this part be bought separately? It’s throwing a P1121 code and reading says change whole throttle body

I already changed the TPS. Did some diagnostics and pulled the plug from the circled part and threw the same code

Why is the cable coming in from the wrong side, is this a Surf?
Edit: nvm the 5vz exists my bad

So can that part be bought alone or gotta buy the whole throttle body?

So was the throttle position sensor tested? {Disconnect the pedal position sensor connector. (b) Using an ohmmeter, measure the resistance between terminals VC and E2. Resistance: 1.2 - 3.2 kΩ at 20°C (68°F)}

Check your parts here (use your VIN for highest accuracy):
Toyota Parts and Accessories - Official Online Store

Not sure of your MY but my '01 has a TPS for about $81 (part no. 8945235020)

If not may find a used one at junk yard, ebay, amazon, ect.

Luck.

That's the electronic throttle that you are unplugging. Unfortunately it's a motorized unit that opens and closes the throttle and the cable is just there as a safety and Toyota sells it as a complete assembly. If it's throwing a code it is most likely needing replacement. Those things are stupid expensive too. I used to sell used ones almost immediately.

I bought a brand new oem TB online. p1121 is what it spat out.

Like I mentioned earlier the TPS didn’t fix the problem.
