I am replacing the TPS Sensor on my 1990 4Runner. The dealer has told me three different part numbers, 89452-12040, 89452-14050, or 89452-28010. I hear this from every place I call. If anyone knows the correct one I would appreciate the response. My 4Runner Info; First eight of the VIN# JT3VN39W, was manufactured in 07-1989, and has a EFI 3.0 liter engine.
