No throttle response

Hi,
I wanted to see if any of you had this problem. My 02 tundra has no throttle response.
Back story, I gave it gas hard one day and it just kind of gave out and I had no throttle response. So I took it off and cleaned it, put it back and nothing. So I'm on a budget so I got one from the junkyard, for now. Well it gave me a TPS code. Bought the TPS and now I'm getting different codes, depending on what position I put the TPS, and still no throttle response. I have the 22030-50142 throttle body. Any help would be greatly appreciated.

 

You took what off and cleaned it and then replaced it?

 

Cable or fly by wire on the first gen?

 

My guess is that you have the same issue I had, being the Acclerator pedal position sensor (APPS). Basically, the early first gens are drive by wire until about halfway down in pedal travel, then are fully mechanical. This went bad in my truck and caused irratic throttle actuation and random loss of power, as well as dead throttle response.

The problem is, Toyota doesn’t sell the part separate from the throttle body, so your options are to 1: but a new throttle body from Toyota, 2: get a junkyard throttle body, or 3, buy and aftermarket sensor, which is still almost $300.

I chose to buy the new sensor. Got it on rock auto, and it’s been solid in the 1500 miles or so that I’ve put in the truck since then.

 

I never knew about the wire to mechanical throttle change over. Always assumed it was wire full time as the wire on the throttle body suggests so.

 

Nope. If you press your pedal all the way down with the truck off you’ll feel the point where the cable kicks in. I’m not sure if it actually changes over when you’re driving, or if it’s completely drive by wire unless something breaks.

 

Hey! This Thread is pretty old so I doubt you’ll see this and reply, but is there any way I could get the link to the part or the name/number of it?
