HABU pilot guy –
Amazon said this did not fit my 85 4Runner. They were wrong. It works just great. Put it on along with the hex screws and set adjustment. Truck runs great. Smooth idle no hesitation and fuel economy went up. I should have replaced tps long ago.

I bought this for my 1985 Toyota 4runner. Mine was running poorly and I had advanced the distributor because it wasn’t advancing far enough to give enough power during acceleration. My truck had a cheap Taiwanese TPS on it that was sticking around 20′-40′.. it was wasted. I put this on in under 30 minutes and now the truck runs like a champ. Highly recommended. Don’t buy cheap Chinese knock offs, go with the quality OEM part.

Is good

I got confused by which TPS I needed, but this one seems to work. Not a big deal to tune, but I did need to remove the throttle body to install. I highly recommend replacing the Philips head screws with socket heads. I wasn’t going to, but then scrounged for some when I realized the annoyance if I had to re-tune.
