First time in 17 years and it finally came on. Checked codes with buddys scan tool and it set codes 51& 52 , having to do with the TPS ( more or less). Bought new TPS at Autozone, appears to be a genuine Toyota part in a Wells box nonethe less. However after installing it and resetting idle speed its still throwing the light at me. What is the proper way to set this thing, I know on my Turbo Buick it is set at .42 at idle, but it only has 3 wires, the Toy has 4, which one should I be tapping into and what is its setting? TIA !!
