Looks like most CV axles from from China are from one of these manufacturers.

Heri - Yuhuan, China

Wohn - Ningbo, China

The ones Pep Boys sells are branded 'Heri' axles...makes sense according to that first link

Alright, so I’m starting to have problems with the Electric Throttle Control System in my 04. Can anyone point me to a thread dealing with these? This is what happened. About a week ago, I had the throttle body out and apart because the motor on the back of the throttle body quit and threw a code. Can’t remember the number, but it said along the lines of, throttle motor clutch circuit fault. The symptoms were a check engine light, and the throttle would not respond until accelerator pedal was pressed 3/4ish of the way down when the accelerator pedal position sensor actually physically actuates the throttle body. I checked for continuity on the pins to the motor with it installed on the truck. The clutch circuit did not have continuity, so I removed the throttle body, removed the motor and took it apart. Everything looks perfect. I put it back together and test for continuity and it has it. Nothing smells burnt, nothing looks burnt. I put power to it with alligator clips and both the clutch and the motor work. Reassemble, reinstall throttle body, clear code, go back to normal operation but with an uneasy feeling about it in the back of my mind. A week of daily driving later, I’m driving into town on a secondary road and go to shift from 3rd to 4th and the thing red lines as soon as I push in the clutch. I turn the ignition off, check to make sure my floor mat didn’t get stuck, turn the key back on before the engine reaches 0 rpm and races back towards redline. I turn the key off, come to a stop, make sure that the rpms are at zero before I turn the key back on, pop the hood, and run out to see what the hell. The pedal positions sensor, (throttle body pulley) is in the throttle closed position, but I can hear the clutch in the motor clicking (sounds like a high amperage solenoid clicking). Turn the key off, turn the key back on, fire it up expecting it to race to red line, but it starts after 5 or so turns (a lot of turns for it) and idles with a check engine light. Throttle won’t respond to pedal input until physical engagement of accelerator position sensor and throttle body valve are made. I drive it home this way (you know how hard it is to drive a manual when your throttle doesn’t respond until it’s almost on the floor?) grab the scanner read the code p2138 accelerator position sensor circuit fault, jiggle the wires to the entire system, clear the code, fire it up and she runs like nothing happens. Put 70-80 miles on it this evening everything from in town driving to mountain secondary road driving to highway driving at 75 and nothing. I plan on pulling the plugs apart tomorrow and cleaning them out with lectra clean, putting dye electric grease on them and seeing what happens. Any one have any constructive input? Don’t really want to just throw parts at it, because the parts are pretty expensive.

Talk to @mechanicjon

I didn’t read through your post entirely, but if it’s the TPS then you’re SOL. Toyota doesn’t sell it separately from the throttle body, and you can’t buy it by itself from anyone else.

The throttle pedal position sensor is separate from the TPS. Did you have the APPS off the throttle body?

I did take the apps off of the throttle body when I had it apart trying to diagnose the issue the first time.

The Aisan at the bottom of the page looks like the 04 - 4-wire. Though this shows out of stock. If somebody can find one.
